From 40266ce18704ad1d9db8c9ab003a9b44564997a5 Mon Sep 17 00:00:00 2001 From: Francisco Date: Mon, 23 Feb 2026 19:01:00 +0100 Subject: [PATCH] [FLINK-24379] Add Glue Schema Registry Avro SQL format factory (avro-glue) Adds a Flink SQL / Table API format factory for AWS Glue Schema Registry with Avro support. Users can now use 'format' = 'avro-glue' in CREATE TABLE statements to read/write Avro data through GSR. Based on the initial implementation by @nicusX. This PR extends that work with: - Shared config infrastructure (GlueFormatOptions, GlueFormatConfigBuilder) - Schema namespace bug fix (avro.namespace, avro.record-name options) - Schema fetch from registry (schema.fetchFromRegistry option) - ProjectableDecodingFormat support - forwardOptions() implementation - Rebase to 6.0-SNAPSHOT - JUnit 5 + AssertJ tests (ported from JUnit 4) - Property-based tests (jqwik) - Integration tests with mock GSR facades Co-authored-by: Nicu Reut --- .../docs/connectors/table/formats/_index.md | 33 + .../docs/connectors/table/formats/_index.md | 35
