From dad00d058bf6f19eb21c02edb1c80ccb6618ec89 Mon Sep 17 00:00:00 2001 From: Ganesh Patil <7030871503ganeshpatil@gmail.com> Date: Tue, 13 Jan 2026 08:43:06 +0530 Subject: [PATCH 01/45] feat(connectors): implement Redshift Sink Connector with S3 staging Implements Issue #2540 - Redshift Sink Connector with S3 staging support. Features: - S3 staging with automatic CSV file upload - Redshift COPY command execution via PostgreSQL wire protocol - IAM role authentication (recommended) or access key credentials - Configurable batch size and compression (gzip, lzop, bzip2, zstd) - Automatic table creation with customizable schema - Retry logic with exponential backoff for transient failures - Automatic cleanup of staged S3 files Configuration options: - connection_string: Redshift cluster connection URL - target_table: Destination table name - iam_role: IAM role ARN for S3 access (recommended) - s3_bucket/s3_region/s3_prefix: S3 staging location - batch_size: Messages per batch (default: 10000) - compression: COPY compression format - delete_staged_files: Auto-cleanup toggle (default: true) - auto_create_table: Create table if missing (default: true) Closes #2540 --- Cargo.lock | 169 +++++++ Cargo.toml | 1 + .../connectors/sinks/redshift_sink/Cargo.toml | 54 ++

Mon Sep 17 00:00:00 2001 From: ryerraguntla Date: Wed, 1 Apr 2026 14:54:45 -0400 Subject: [PATCH 12/45] Initial version merging with iggy master with earlier Redshift S3 effort with latest S3 crate Migrate S3 usage from rust-s3 to s3-tokio and update related dependencies. Top-level Cargo.toml updated (http, lz4_flex, toml) and DEPENDENCIES.md adjusted. redshift_sink/Cargo.toml switched to s3-tokio, made sqlx a workspace dependency and added rustls as a dev-dependency. Code changes: S3Uploader now owns Bucket (removed Box) and tests install the rustls crypto provider. Integration tests were refactored to remove the manual testcontainers setup in favor of the iggy_harness-based test harness. --- Cargo.lock | 143 ++++++++---------- Cargo.toml | 8 +- DEPENDENCIES.md |

Introduce a new core/connectors/influxdb_common crate that provides a version-abstraction layer for InfluxDB (InfluxDB V2 and V3). Adds the InfluxDbAdapter trait, ApiVersion factory, line-protocol escaping helpers, CSV/JSONL response parsers, and concrete V2/V3 adapters plus unit tests and architecture notes. Wire the new crate into the workspace (Cargo.toml/Cargo.lock) and update existing influxdb sink/source connector manifests/sources to depend on it. Also add integration test fixtures and v3-specific integration tests and configs to exercise V3 behavior. --- Cargo.lock | 14 + Cargo.toml | 2 + core/connectors/influxdb_common/Cargo.toml | 39 ++ .../connectors/influxdb_common/src/adapter.rs | 116 ++++++ core/connectors/influxdb_common/src/config.rs | 120 +++++++ core/connectors/influxdb_common/src/lib.rs | 65 ++++ .../influxdb_common/src/protocol.rs | 153 ++++++++ core/connectors/influxdb_common/src/row.rs | 284 +++++++++++++++ core/connectors/influxdb_common/src/v2.rs | 200 +++++++++++ core/connectors/influxdb_common/src/v3.rs | 194 ++++++++++ core/connectors/influxdb_v3_architecture.md | 202 +++++++++++ .../connectors/sinks/influxdb_sink/Cargo.toml | 1 + .../connectors/sinks/influxdb_sink/src/lib.rs | 211 ++++++----- .../connectors/sinks/quickwit_sink/Cargo.toml | 1 + .../sources/influxdb_source/Cargo.toml | 1 + .../sources/influxdb_source/src/lib.rs | 338 ++++++++++++------ .../fixtures/influxdb/container_v3.rs | 246 +++++++++++++ .../tests/connectors/fixtures/influxdb/mod.rs | 5 + .../connectors/fixtures/influxdb/sink_v3.rs | 152 ++++++++ .../connectors/fixtures/influxdb/source_v3.rs | 145 ++++++++ .../tests/connectors/fixtures/mod.rs | 6 +- .../connectors/influxdb/docker-compose.yml | 28 ++ .../connectors/influxdb/influxdb_sink_v3.rs | 223 ++++++++++++ .../connectors/influxdb/influxdb_source_v3.rs | 241 +++++++++++++ .../tests/connectors/influxdb/mod.rs | 2 + .../tests/connectors/influxdb/sink_v3.toml | 36 ++ .../tests/connectors/influxdb/source_v3.toml | 26 ++ 27 files changed, 2866 insertions(+), 185 deletions(-) create mode 100644 core/connectors/influxdb_common/Cargo.toml create mode 100644 core/connectors/influxdb_common/src/adapter.rs create mode 100644 core/connectors/influxdb_common/src/config.rs create mode 100644 core/connectors/influxdb_common/src/lib.rs create mode 100644 core/connectors/influxdb_common/src/protocol.rs create mode 100644 core/connectors/influxdb_common/src/row.rs create mode 100644 core/connectors/influxdb_common/src/v2.rs create mode 100644 core/connectors/influxdb_common/src/v3.rs create mode 100644 core/connectors/influxdb_v3_architecture.md create mode 100644 core/integration/tests/connectors/fixtures/influxdb/container_v3.rs create mode 100644 core/integration/tests/connectors/fixtures/influxdb/sink_v3.rs create mode 100644 core/integration/tests/connectors/fixtures/influxdb/source_v3.rs create mode 100644 core/integration/tests/connectors/influxdb/influxdb_sink_v3.rs create mode 100644 core/integration/tests/connectors/influxdb/influxdb_source_v3.rs create mode 100644 core/integration/tests/connectors/influxdb/sink_v3.toml create mode 100644 core/integration/tests/connectors/influxdb/source_v3.toml diff --git a/Cargo.lock b/Cargo.lock index 4b06e59d21..d1f695ca2c 100644 --- a/Cargo.lock +++ b/Cargo.lock @@ -5588,6 +5588,17 @@ dependencies = [ "uuid", ] +[[package]] +name = "iggy_connector_influxdb_common" +version = "0.1.0-edge.1" +dependencies = [ + "csv", + "iggy_connector_sdk", + "reqwest 0.13.2", + "serde_json", + "tracing", +] + [[package]] name = "iggy_connector_influxdb_sink" version = "0.1.0-edge.1" @@ -5598,6 +5609,7 @@ dependencies = [ "dashmap", "futures", "iggy_common", + "iggy_connector_influxdb_common", "iggy_connector_sdk", "once_cell", "reqwest 0.13.2", @@ -5620,6 +5632,7 @@ dependencies = [ "dashmap", "futures", "iggy_common", + "iggy_connector_influxdb_common", "iggy_connector_sdk", "once_cell", "regex", @@ -5703,6 +5716,7 @@ dependencies = [ "serde", "serde_yaml_ng", "simd-json", + "tokio", "tracing", ] diff --git a/Cargo.toml b/Cargo.toml index 590a39199a..dc7117fb04 100644 --- a/Cargo.toml +++ b/Cargo.toml @@ -31,6 +31,7 @@ members = [ "core/common", "core/configs", "core/configs_derive", + "core/connectors/influxdb_common", "core/connectors/runtime", "core/connectors/sdk", "core/connectors/sinks/elasticsearch_sink", @@ -169,6 +170,7 @@ iggy = { path = "core/sdk", version = "0.9.5-edge.1" } iggy-cli = { path = "core/cli", version = "0.12.1-edge.1" } iggy_binary_protocol = { path = "core/binary_protocol", version = "0.9.5-edge.1" } iggy_common = { path = "core/common", version = "0.9.5-edge.1" } +iggy_connector_influxdb_common = { path = "core/connectors/influxdb_common", version = "0.1.0-edge.1" } iggy_connector_sdk = { path = "core/connectors/sdk", version = "0.2.2-edge.1" } integration = { path = "core/integration" } iobuf = { path = "core/iobuf" } diff --git a/core/connectors/influxdb_common/Cargo.toml b/core/connectors/influxdb_common/Cargo.toml new file mode 100644 index 0000000000..43262c5f6f --- /dev/null +++ b/core/connectors/influxdb_common/Cargo.toml @@ -0,0 +1,39 @@ +# Licensed to the Apache Software Foundation (ASF) under one +# or more contributor license agreements.

Key changes: - Removed iggy_connector_influxdb_common dependency (Cargo.toml & Cargo.lock) and inlined adapter logic. - Introduced InfluxDbSinkConfig enum with V2/V3 variants and helper methods (url, auth header, build_write_url/health_url, precision mapping, feature flags, etc.). - Reworked InfluxDbSink struct: store unified config, auth_header, measurement/precision, metadata flags, batch size limit, and other derived fields. - Added line-protocol escaping helpers (write_measurement, write_tag_value, write_field_string) and simplified PayloadFormat handling. - Adjusted client initialization, connectivity checks, retry middleware setup, and improved error messages and transient vs permanent error handling. - Updated Sink impl: open(), consume(), process/ batching, circuit breaker interactions, and close() behavior. - Expanded and updated unit tests to cover v2/v3 config behavior, URL/precision mapping, escaping, and append_line error/success cases. - Added new source modules and test script files related to InfluxDB connectors. This refactor centralises version-specific behaviour, improves configurability, and prepares the connector for V3 line-protocol and auth differences. --- Cargo.lock | 2 - .../connectors/sinks/influxdb_sink/Cargo.toml | 1 - .../connectors/sinks/influxdb_sink/src/lib.rs | 1721 ++++++----------- .../sources/influxdb_source/Cargo.toml | 1 - .../sources/influxdb_source/src/common.rs | 563 ++++++ .../sources/influxdb_source/src/lib.rs | 1716 ++++------------ .../sources/influxdb_source/src/v2.rs | 267 +++ .../sources/influxdb_source/src/v3.rs | 374 ++++ .../connectors/fixtures/influxdb/container.rs | 9 +- .../fixtures/influxdb/container_v3.rs | 6 +- .../connectors/fixtures/influxdb/sink.rs | 5 +- .../connectors/fixtures/influxdb/sink_v3.rs | 6 +- .../connectors/fixtures/influxdb/source.rs | 5 +- .../connectors/fixtures/influxdb/source_v3.rs | 12 +- .../scripts/test-connectors.sh | 233 +++ 15 files changed, 2462 insertions(+), 2459 deletions(-) create mode 100644 core/connectors/sources/influxdb_source/src/common.rs create mode 100644 core/connectors/sources/influxdb_source/src/v2.rs create mode 100644 core/connectors/sources/influxdb_source/src/v3.rs create mode 100755 influx_dB_test_proc_docs/scripts/test-connectors.sh diff --git a/Cargo.lock b/Cargo.lock index d1f695ca2c..f12700b439 100644 --- a/Cargo.lock +++ b/Cargo.lock @@ -5609,7 +5609,6 @@ dependencies = [ "dashmap", "futures", "iggy_common", - "iggy_connector_influxdb_common", "iggy_connector_sdk", "once_cell", "reqwest 0.13.2", @@ -5632,7 +5631,6 @@ dependencies = [ "dashmap", "futures", "iggy_common", - "iggy_connector_influxdb_common", "iggy_connector_sdk", "once_cell", "regex", diff --git a/core/connectors/sinks/influxdb_sink/Cargo.toml b/core/connectors/sinks/influxdb_sink/Cargo.toml index ea2ba366d9..c7f3e65fd4 100644 --- a/core/connectors/sinks/influxdb_sink/Cargo.toml +++ b/core/connectors/sinks/influxdb_sink/Cargo.toml @@ -41,7 +41,6 @@ bytes = { workspace = true } dashmap = { workspace = true } futures = { workspace = true } iggy_common = { workspace = true } -iggy_connector_influxdb_common = { workspace = true } iggy_connector_sdk = { workspace = true } once_cell = { workspace = true } reqwest = { workspace = true } diff --git a/core/connectors/sinks/influxdb_sink/src/lib.rs b/core/connectors/sinks/influxdb_sink/src/lib.rs index cdf0bc9ec7..51394fe7c1 100644 --- a/core/connectors/sinks/influxdb_sink/src/lib.rs +++ b/core/connectors/sinks/influxdb_sink/src/lib.rs @@ -20,9 +20,6 @@ use async_trait::async_trait; use base64::{Engine as _, engine::general_purpose}; use bytes::Bytes; use iggy_common::serde_secret::serialize_secret; -use iggy_connector_influxdb_common::{ - ApiVersion, InfluxDbAdapter, write_field_string, write_measurement, write_tag_value, -}; use iggy_connector_sdk::retry::{ CircuitBreaker, ConnectivityConfig, build_retry_client, check_connectivity_with_retry, parse_duration, @@ -34,65 +31,30 @@ use reqwest::Url; use reqwest_middleware::ClientWithMiddleware; use secrecy::{ExposeSecret, SecretString}; use serde::{Deserialize, Serialize}; +use std::fmt::Write as _; use std::sync::Arc; use std::sync::atomic::{AtomicU64, Ordering}; -use std::time::Duration; -use std::time::SystemTime; -use std::time::UNIX_EPOCH; +use std::time::{Duration, SystemTime, UNIX_EPOCH}; use tracing::{debug, error, info, warn}; + sink_connector!(InfluxDbSink); const DEFAULT_MAX_RETRIES: u32 = 3; const DEFAULT_RETRY_DELAY: &str = "1s"; const DEFAULT_TIMEOUT: &str = "30s"; const DEFAULT_PRECISION: &str = "us"; -// Maximum attempts for open() connectivity retries const DEFAULT_MAX_OPEN_RETRIES: u32 = 10; -// Cap for exponential backoff in open() — never wait longer than this const DEFAULT_OPEN_RETRY_MAX_DELAY: &str = "60s"; -// Cap for exponential backoff on per-write retries — kept short so a -// transient InfluxDB blip does not stall message delivery for too long const DEFAULT_RETRY_MAX_DELAY: &str = "5s"; -// How many consecutive batch failures open the circuit breaker const DEFAULT_CIRCUIT_BREAKER_THRESHOLD: u32 = 5; -// How long the circuit stays open before allowing a probe attempt const DEFAULT_CIRCUIT_COOL_DOWN: &str = "30s"; -// --------------------------------------------------------------------------- -// Main connector structs -// --------------------------------------------------------------------------- - -#[derive(Debug)] -pub struct InfluxDbSink { - pub id: u32, - config: InfluxDbSinkConfig, - /// `None` until `open()` is called.

Introduces delegate! macros to remove repetitive variant matching, unifies URL/auth handling via InfluxDbAdapter (including V3 precision mapping), and centralises line-protocol escaping/row parsing. Optimises body construction (build_body) and Bytes usage, adds extensive unit & HTTP integration tests (axum dev-dep), and updates Cargo.toml entries accordingly to reflect the new shared dependency. --- Cargo.lock | 7 +- core/connectors/influxdb_common/src/config.rs | 4 - .../influxdb_common/src/protocol.rs | 4 - core/connectors/influxdb_common/src/row.rs | 12 +- core/connectors/influxdb_common/src/v2.rs | 4 - core/connectors/influxdb_common/src/v3.rs | 30 +- .../connectors/sinks/influxdb_sink/Cargo.toml | 10 +- .../connectors/sinks/influxdb_sink/src/lib.rs | 935 ++++++++++++++---- .../sources/influxdb_source/Cargo.toml | 4 + .../sources/influxdb_source/src/common.rs | 450 ++++----- .../sources/influxdb_source/src/lib.rs | 123 +-- .../sources/influxdb_source/src/v2.rs | 848 ++++++++++++++-- .../sources/influxdb_source/src/v3.rs | 855 +++++++++++++--- .../connectors/fixtures/influxdb/container.rs | 13 +- .../fixtures/influxdb/container_v3.rs | 12 +- .../connectors/fixtures/influxdb/sink.rs | 5 +- .../connectors/fixtures/influxdb/sink_v3.rs | 6 +- .../connectors/fixtures/influxdb/source_v3.rs | 6 +- 18 files changed, 2524 insertions(+), 804 deletions(-) diff --git a/Cargo.lock b/Cargo.lock index f12700b439..fba6f8a04f 100644 --- a/Cargo.lock +++ b/Cargo.lock @@ -5604,13 +5604,12 @@ name = "iggy_connector_influxdb_sink" version = "0.1.0-edge.1" dependencies = [ "async-trait", + "axum", "base64 0.22.1", "bytes", - "dashmap", - "futures", "iggy_common", + "iggy_connector_influxdb_common", "iggy_connector_sdk", - "once_cell", "reqwest 0.13.2", "reqwest-middleware", "secrecy", @@ -5626,11 +5625,13 @@ name = "iggy_connector_influxdb_source" version = "0.1.0-edge.1" dependencies = [ "async-trait", + "axum", "base64 0.22.1", "csv", "dashmap", "futures", "iggy_common", + "iggy_connector_influxdb_common", "iggy_connector_sdk", "once_cell", "regex", diff --git a/core/connectors/influxdb_common/src/config.rs b/core/connectors/influxdb_common/src/config.rs index d5653dfc5d..9666c5fd98 100644 --- a/core/connectors/influxdb_common/src/config.rs +++ b/core/connectors/influxdb_common/src/config.rs @@ -72,10 +72,6 @@ impl ApiVersion { } } -// --------------------------------------------------------------------------- -// Unit tests -// --------------------------------------------------------------------------- - #[cfg(test)] mod tests { use super::*;

Add tests that verify write_url percent-encodes bucket/org/db query parameters and that decoding recovers the original values. Improve CSV row parsing by preallocating Row with capacity based on active headers. Clean up influxdb_source Cargo.toml by removing unused csv and futures deps, add a comment explaining dashmap/once_cell are required due to macro expansion, and update the ignored list. --- Cargo.lock | 2 -- core/connectors/influxdb_common/src/row.rs | 2 +- core/connectors/influxdb_common/src/v2.rs | 36 ++++++++++++++++++- core/connectors/influxdb_common/src/v3.rs | 31 +++++++++++++++- .../sources/influxdb_source/Cargo.toml | 10 ++++-- 5 files changed, 73 insertions(+), 8 deletions(-) diff --git a/Cargo.lock b/Cargo.lock index fba6f8a04f..79b119964a 100644 --- a/Cargo.lock +++ b/Cargo.lock @@ -5627,9 +5627,7 @@ dependencies = [ "async-trait", "axum", "base64 0.22.1", - "csv", "dashmap", - "futures", "iggy_common", "iggy_connector_influxdb_common", "iggy_connector_sdk", diff --git a/core/connectors/influxdb_common/src/row.rs b/core/connectors/influxdb_common/src/row.rs index 9d4772c468..df98cbd6e2 100644 --- a/core/connectors/influxdb_common/src/row.rs +++ b/core/connectors/influxdb_common/src/row.rs @@ -88,7 +88,7 @@ pub fn parse_csv_rows(csv_text: &str) -> Result, Error> { continue;

add tests. - Simplify auth header and health URL construction (removed dynamic adapter usage for these paths). - Ensure circuit breaker records successes for successful batches and move record_success into the per-batch success path; add a test to prevent tripping on intermittent failures. - Change several atomic counter loads to SeqCst for correctness in tests and tighten an unreachable branch where precision is validated. - Minor protocol.rs doc clarifications about tab escaping in line protocol. Includes multiple unit/integration tests covering the new validations and circuit-breaker behavior. --- .../influxdb_common/src/protocol.rs | 6 + .../connectors/sinks/influxdb_sink/src/lib.rs | 136 +++++++++++++----- .../sources/influxdb_source/src/common.rs | 23 ++- .../sources/influxdb_source/src/lib.rs | 86 ++++++++++- .../sources/influxdb_source/src/v3.rs | 34 +++++ 5 files changed, 249 insertions(+), 36 deletions(-) diff --git a/core/connectors/influxdb_common/src/protocol.rs b/core/connectors/influxdb_common/src/protocol.rs index 02510de771..0a74d1b906 100644 --- a/core/connectors/influxdb_common/src/protocol.rs +++ b/core/connectors/influxdb_common/src/protocol.rs @@ -71,6 +71,12 @@ pub fn write_tag_value(buf: &mut String, value: &str) { /// Newline and carriage-return are the InfluxDB line-protocol record /// delimiters; a literal newline inside a string field value would split the /// line and corrupt the batch. +/// +/// Tab (`\t`) is intentionally NOT escaped here.

Workspace Cargo.toml and Cargo.lock were updated to remove the member/dependency and to add CSV where needed; tests were adapted/added for the inlined helpers and validation behavior. --- Cargo.lock | 14 +- Cargo.toml | 2 - core/connectors/influxdb_common/Cargo.toml | 39 --- .../connectors/influxdb_common/src/adapter.rs | 109 ------- core/connectors/influxdb_common/src/config.rs | 114 ------- core/connectors/influxdb_common/src/lib.rs | 65 ---- core/connectors/influxdb_common/src/v2.rs | 269 ----------------- core/connectors/influxdb_common/src/v3.rs | 282 ------------------ .../connectors/sinks/influxdb_sink/Cargo.toml | 1 - .../connectors/sinks/influxdb_sink/src/lib.rs | 111 +++++-- .../influxdb_sink}/src/protocol.rs | 6 +- .../sources/influxdb_source/Cargo.toml | 2 +- .../sources/influxdb_source/src/common.rs | 2 +- .../sources/influxdb_source/src/lib.rs | 38 +-- .../influxdb_source}/src/row.rs | 6 +- .../sources/influxdb_source/src/v2.rs | 75 ++++- .../sources/influxdb_source/src/v3.rs | 66 ++-- 17 files changed, 231 insertions(+), 970 deletions(-) delete mode 100644 core/connectors/influxdb_common/Cargo.toml delete mode 100644 core/connectors/influxdb_common/src/adapter.rs delete mode 100644 core/connectors/influxdb_common/src/config.rs delete mode 100644 core/connectors/influxdb_common/src/lib.rs delete mode 100644 core/connectors/influxdb_common/src/v2.rs delete mode 100644 core/connectors/influxdb_common/src/v3.rs rename core/connectors/{influxdb_common => sinks/influxdb_sink}/src/protocol.rs (97%) rename core/connectors/{influxdb_common => sources/influxdb_source}/src/row.rs (98%) diff --git a/Cargo.lock b/Cargo.lock index 79b119964a..02adce0e55 100644 --- a/Cargo.lock +++ b/Cargo.lock @@ -5588,17 +5588,6 @@ dependencies = [ "uuid", ] -[[package]] -name = "iggy_connector_influxdb_common" -version = "0.1.0-edge.1" -dependencies = [ - "csv", - "iggy_connector_sdk", - "reqwest 0.13.2", - "serde_json", - "tracing", -] - [[package]] name = "iggy_connector_influxdb_sink" version = "0.1.0-edge.1" @@ -5608,7 +5597,6 @@ dependencies = [ "base64 0.22.1", "bytes", "iggy_common", - "iggy_connector_influxdb_common", "iggy_connector_sdk", "reqwest 0.13.2", "reqwest-middleware", @@ -5627,9 +5615,9 @@ dependencies = [ "async-trait", "axum", "base64 0.22.1", + "csv", "dashmap", "iggy_common", - "iggy_connector_influxdb_common", "iggy_connector_sdk", "once_cell", "regex", diff --git a/Cargo.toml b/Cargo.toml index dc7117fb04..590a39199a 100644 --- a/Cargo.toml +++ b/Cargo.toml @@ -31,7 +31,6 @@ members = [ "core/common", "core/configs", "core/configs_derive", - "core/connectors/influxdb_common", "core/connectors/runtime", "core/connectors/sdk", "core/connectors/sinks/elasticsearch_sink", @@ -170,7 +169,6 @@ iggy = { path = "core/sdk", version = "0.9.5-edge.1" } iggy-cli = { path = "core/cli", version = "0.12.1-edge.1" } iggy_binary_protocol = { path = "core/binary_protocol", version = "0.9.5-edge.1" } iggy_common = { path = "core/common", version = "0.9.5-edge.1" } -iggy_connector_influxdb_common = { path = "core/connectors/influxdb_common", version = "0.1.0-edge.1" } iggy_connector_sdk = { path = "core/connectors/sdk", version = "0.2.2-edge.1" } integration = { path = "core/integration" } iobuf = { path = "core/iobuf" } diff --git a/core/connectors/influxdb_common/Cargo.toml b/core/connectors/influxdb_common/Cargo.toml deleted file mode 100644 index 43262c5f6f..0000000000 --- a/core/connectors/influxdb_common/Cargo.toml +++ /dev/null @@ -1,39 +0,0 @@ -# Licensed to the Apache Software Foundation (ASF) under one -# or more contributor license agreements.

Add V3-specific options and safety checks: introduce include_metadata to omit the cursor field from emitted payloads, add QUERY_FORMAT_JSONL, and enforce MAX_STUCK_CAP_FACTOR (100) with validation on open to avoid extremely large queries. Make timestamp comparison conservative (return false on parse failure) to avoid skipping data. Switch message ID generation to per-message UUIDs (remove uuid_base usage), adjust payload building to filter cursor when include_metadata=false, and small sink fix to append lines without producing trailing newlines. Update and add tests covering config deserialization, timestamp behavior, stuck-cap validation, and other affected behaviors. --- .../connectors/sinks/influxdb_sink/src/lib.rs | 62 ++++++++- .../sources/influxdb_source/src/common.rs | 128 ++++++++++++++++-- .../sources/influxdb_source/src/lib.rs | 46 +++++++ .../sources/influxdb_source/src/row.rs | 2 +- .../sources/influxdb_source/src/v2.rs | 57 ++------ .../sources/influxdb_source/src/v3.rs | 80 +++++++---- 6 files changed, 291 insertions(+), 84 deletions(-) diff --git a/core/connectors/sinks/influxdb_sink/src/lib.rs b/core/connectors/sinks/influxdb_sink/src/lib.rs index a67cd275b7..e791f908bb 100644 --- a/core/connectors/sinks/influxdb_sink/src/lib.rs +++ b/core/connectors/sinks/influxdb_sink/src/lib.rs @@ -109,7 +109,7 @@ pub struct V3SinkConfig { pub circuit_breaker_cool_down: Option, } -#[derive(Debug, Clone, Serialize, Deserialize)] +#[derive(Debug, Clone, Serialize)] #[serde(tag = "version")] pub enum InfluxDbSinkConfig { #[serde(rename = "v2")] @@ -118,6 +118,24 @@ pub enum InfluxDbSinkConfig { V3(V3SinkConfig), } +impl<'de> serde::Deserialize<'de> for InfluxDbSinkConfig { + fn deserialize>(d: D) -> Result { + let raw = serde_json::Value::deserialize(d)?; + let version = raw.get("version").and_then(|v| v.as_str()).unwrap_or("v2"); + match version { + "v2" => serde_json::from_value::(raw) + .map(Self::V2) + .map_err(serde::de::Error::custom), + "v3" => serde_json::from_value::(raw) + .map(Self::V3) + .map_err(serde::de::Error::custom), + other => Err(serde::de::Error::custom(format!( + "unknown InfluxDB version {other:?}; expected \"v2\" or \"v3\"" + ))), + } + } +} + /// Map a short precision string to InfluxDB 3's long-form equivalent. /// /// InfluxDB 3 rejects the short forms (`"ns"`, `"us"`, `"ms"`, `"s"`) on the @@ -528,10 +546,10 @@ impl InfluxDbSink { // payloads without excessive reallocation. let mut body = String::with_capacity(messages.len() * 1024); for (i, msg) in messages.iter().enumerate() { - if i > 0 { + self.append_line(&mut body, topic_metadata, messages_metadata, msg)?; + if i + 1 < messages.len() { body.push('\n'); } - self.append_line(&mut body, topic_metadata, messages_metadata, msg)?; } Ok(body) } @@ -827,6 +845,44 @@ mod tests { } } + // ── config deserialization ──────────────────────────────────────────── + + #[test] + fn sink_config_without_version_defaults_to_v2() { + let json = r#"{"url":"http://localhost:8086","org":"o","bucket":"b","token":"t"}"#; + let raw: serde_json::Value = serde_json::from_str(json).unwrap(); + let config: InfluxDbSinkConfig = serde_json::from_value(raw).unwrap(); + assert!(matches!(config, InfluxDbSinkConfig::V2(_))); + } + + #[test] + fn sink_config_with_explicit_v2_version_deserializes_v2() { + let json = + r#"{"version":"v2","url":"http://localhost:8086","org":"o","bucket":"b","token":"t"}"#; + let config: InfluxDbSinkConfig = serde_json::from_str(json).unwrap(); + assert!(matches!(config, InfluxDbSinkConfig::V2(_))); + } + + #[test] + fn sink_config_with_version_v3_deserializes_v3() { + let json = r#"{"version":"v3","url":"http://localhost:8181","db":"d","token":"t"}"#; + let config: InfluxDbSinkConfig = serde_json::from_str(json).unwrap(); + assert!(matches!(config, InfluxDbSinkConfig::V3(_))); + } + + #[test] + fn sink_config_unknown_version_returns_error() { + let json = r#"{"version":"v9","url":"http://x","org":"o","bucket":"b","token":"t"}"#; + let result = serde_json::from_str::(json); + assert!(result.is_err()); + assert!( + result + .unwrap_err() + .to_string() + .contains("unknown InfluxDB version") + ); + } + // ── config ──────────────────────────────────────────────────────────── #[test] diff --git a/core/connectors/sources/influxdb_source/src/common.rs b/core/connectors/sources/influxdb_source/src/common.rs index 8efa53c651..8ecdfb0cbe 100644 --- a/core/connectors/sources/influxdb_source/src/common.rs +++ b/core/connectors/sources/influxdb_source/src/common.rs @@ -32,7 +32,7 @@ pub(crate) use crate::row::{Row, parse_csv_rows, parse_jsonl_rows}; // serde's flatten interacts poorly with tagged enums — the tag field can be // consumed before the variant content is parsed, causing deserialization to fail. -#[derive(Debug, Clone, Serialize, Deserialize)] +#[derive(Debug, Clone, Serialize)] #[serde(tag = "version")] pub enum InfluxDbSourceConfig { #[serde(rename = "v2")] @@ -41,6 +41,29 @@ pub enum InfluxDbSourceConfig { V3(V3SourceConfig), } +/// Deserializes `InfluxDbSourceConfig` with backward-compatible version defaulting. +/// +/// Existing V2 configs that omit the `version` field are treated as `"v2"` so +/// deployments can upgrade without touching their config files.

validate V2 org is non-empty in sink config. - Introduce RowContext to consolidate per-poll parameters passed to row-processing routines; simplify signatures for process_rows and poll functions and propagate include_metadata consistently. - Optimize per-message UUID generation by deriving IDs from a single per-poll base UUID to reduce PRNG calls. - Add query_has_sort_call heuristic to detect Flux sort() calls (avoids false positives on identifier prefixes) and use it when checking V2 queries. - Improve error messages for cursor_field validation to be version-specific and add related tests. - Add comments clarifying escaping rules and rationale for using simd_json in the sink hot path. - Update integration test TOML keys from api_version to version and add unit tests verifying TOML deserialization defaults and behavior. These changes are focused on robustness, performance, and clearer configuration/validation behavior. --- Cargo.lock | 2 + .../connectors/sinks/influxdb_sink/Cargo.toml | 1 + .../sinks/influxdb_sink/config.toml | 1 + .../connectors/sinks/influxdb_sink/src/lib.rs | 158 ++++++++++------ .../sources/influxdb_source/Cargo.toml | 1 + .../sources/influxdb_source/config.toml | 1 + .../sources/influxdb_source/src/common.rs | 178 +++++++++++------ .../sources/influxdb_source/src/lib.rs | 69 ++++++- .../sources/influxdb_source/src/v2.rs | 179 ++++++------------ .../sources/influxdb_source/src/v3.rs | 132 +++++++------ .../tests/connectors/influxdb/sink_v3.toml | 2 +- .../tests/connectors/influxdb/source_v3.toml | 2 +- 12 files changed, 431 insertions(+), 295 deletions(-) diff --git a/Cargo.lock b/Cargo.lock index 02adce0e55..6ad710c0a8 100644 --- a/Cargo.lock +++ b/Cargo.lock @@ -5605,6 +5605,7 @@ dependencies = [ "serde_json", "simd-json", "tokio", + "toml 1.1.1+spec-1.1.0", "tracing", ] @@ -5627,6 +5628,7 @@ dependencies = [ "serde", "serde_json", "tokio", + "toml 1.1.1+spec-1.1.0", "tracing", "uuid", ] diff --git a/core/connectors/sinks/influxdb_sink/Cargo.toml b/core/connectors/sinks/influxdb_sink/Cargo.toml index 8721bb3ade..db0a265a1b 100644 --- a/core/connectors/sinks/influxdb_sink/Cargo.toml +++ b/core/connectors/sinks/influxdb_sink/Cargo.toml @@ -48,3 +48,4 @@ tracing = { workspace = true } [dev-dependencies] axum = { workspace = true } +toml = { workspace = true } diff --git a/core/connectors/sinks/influxdb_sink/config.toml b/core/connectors/sinks/influxdb_sink/config.toml index 621c6e7f77..7d32488c5f 100644 --- a/core/connectors/sinks/influxdb_sink/config.toml +++ b/core/connectors/sinks/influxdb_sink/config.toml @@ -32,6 +32,7 @@ poll_interval = "5ms" consumer_group = "influxdb_sink" [plugin_config] +version = "v2" url = "http://localhost:8086" org = "iggy" bucket = "events" diff --git a/core/connectors/sinks/influxdb_sink/src/lib.rs b/core/connectors/sinks/influxdb_sink/src/lib.rs index e791f908bb..b8cde48ce2 100644 --- a/core/connectors/sinks/influxdb_sink/src/lib.rs +++ b/core/connectors/sinks/influxdb_sink/src/lib.rs @@ -56,57 +56,57 @@ const DEFAULT_CIRCUIT_COOL_DOWN: &str = "30s";

Key changes: - Reflow long argument lists and await expressions in influxdb_source lib and v3 for readability. - Tweak validate_cursor_field error message construction and test unwrap_err formatting in common.rs. - Use Option::is_none_or in query_has_sort_call and adjust related tests formatting. - Simplify container port mapping in Elasticsearch and MongoDB fixtures: collapse intermediate `ports` variable into `mapped_port` and remove the IPv6 fallback mapping. - Update Cargo.lock entries (add/remove/normalize some deps, e.g. axum, tokio, toml, simd-json; normalize lz4_flex entry and remove explicit package block). These are mostly non-functional formatting and small API-use changes to improve code clarity and dependency resolution. --- Cargo.lock | 23 ++++++--------- .../sources/influxdb_source/src/common.rs | 19 ++++++++++--- .../sources/influxdb_source/src/lib.rs | 28 ++++++++++++++++--- .../sources/influxdb_source/src/v3.rs | 5 +++- .../fixtures/elasticsearch/container.rs | 6 ++-- .../connectors/fixtures/mongodb/container.rs | 12 +++----- 6 files changed, 57 insertions(+), 36 deletions(-) diff --git a/Cargo.lock b/Cargo.lock index f1a4280d57..c6546f5e38 100644 --- a/Cargo.lock +++ b/Cargo.lock @@ -5783,13 +5783,11 @@ name = "iggy_connector_influxdb_sink" version = "0.4.0" dependencies = [ "async-trait", + "axum", "base64 0.22.1", "bytes", - "dashmap", - "futures", "iggy_common", "iggy_connector_sdk", - "once_cell", "reqwest 0.13.2", "reqwest-middleware", "secrecy", @@ -5797,6 +5795,7 @@ dependencies = [ "serde_json", "simd-json", "tokio", + "toml 1.1.2+spec-1.1.0", "tracing", ] @@ -5805,10 +5804,10 @@ name = "iggy_connector_influxdb_source" version = "0.4.0" dependencies = [ "async-trait", + "axum", "base64 0.22.1", "csv", "dashmap", - "futures", "iggy_common", "iggy_connector_sdk", "once_cell", @@ -5818,7 +5817,9 @@ dependencies = [ "secrecy", "serde", "serde_json", + "simd-json", "tokio", + "toml 1.1.2+spec-1.1.0", "tracing", "uuid", ] @@ -5893,6 +5894,7 @@ dependencies = [ "serde", "serde_yaml_ng", "simd-json", + "tokio", "tracing", ] @@ -5974,7 +5976,7 @@ dependencies = [ "futures-util", "iggy", "iggy_common", - "lz4_flex 0.13.0", + "lz4_flex", "rand 0.10.1", "serde", "serde_json", @@ -6880,15 +6882,6 @@ dependencies = [ "twox-hash", ] -[[package]] -name = "lz4_flex" -version = "0.13.0" -source = "registry+https://github.com/rust-lang/crates.io-index" -checksum = "db9a0d582c2874f68138a16ce1867e0ffde6c0bb0a0df85e1f36d04146db488a" -dependencies = [ - "twox-hash", -] - [[package]] name = "macro_magic" version = "0.5.1" @@ -7954,7 +7947,7 @@ dependencies = [ "futures", "half", "hashbrown 0.16.1", - "lz4_flex 0.12.1", + "lz4_flex", "num-bigint", "num-integer", "num-traits", diff --git a/core/connectors/sources/influxdb_source/src/common.rs b/core/connectors/sources/influxdb_source/src/common.rs index d3938d7481..5f7dafd6e4 100644 --- a/core/connectors/sources/influxdb_source/src/common.rs +++ b/core/connectors/sources/influxdb_source/src/common.rs @@ -378,7 +378,11 @@ pub fn validate_cursor_field(field: &str, version: &str) -> Result<(), Error> { .into(), )), (other, _) => { - let suggestion = if version == "v2" { "\"_time\"" } else { "\"time\"" };

Also updates Cargo.toml to include chrono and corresponding lockfile changes.
