Zixir v6.0.0 — Major Release ⭐ RECOMMENDED

Major release with VectorDB backend expansion and cloud resilience. Nine backends supported; cloud backends use connection pooling, exponential backoff, circuit breaker, query caching, health checks, and request metrics. Follows semantic versioning (new backends + resilience = major).

New Features & Improvements

VectorDB: 3 new backends (9 total)

Backend Type Best For
:pgvector Python PostgreSQL users, ACID compliance
:redis Python Real-time apps, sub-ms latency
:azure Python Microsoft ecosystems

Existing: :memory, :chroma, :pinecone, :weaviate, :qdrant, :milvus.

Cloud backends: real-world resilience

Feature Benefit
Connection Pooling Better resource utilization
Exponential Backoff Handles transient failures gracefully
Circuit Breaker Prevents cascade failures
Query Caching Reduces redundant DB calls
Health Checks Real-time monitoring
Request Metrics Track latency, success rates

Documentation

  • docs/VECTORDB_BACKENDS.md — Setup and pip install for each backend; resilience options; examples for create/health/metrics from Elixir.
