Summary

  • Add RedisChatMemoryRepository implementing ChatMemoryRepository interface
  • Add AdvancedChatMemoryRepository for extended query capabilities (search by metadata, time ranges, pagination)
  • Add RedisChatMemoryConfig for flexible configuration options
  • Add Spring Boot auto-configuration for Redis chat memory
  • Include comprehensive test coverage

Details

This PR adds Redis-based chat memory persistence using Redis Stack's JSON and Search capabilities. The implementation provides:

  • Full ChatMemoryRepository interface support: Store, retrieve, and manage conversation messages
  • Advanced querying: Search messages by metadata fields, time ranges, and content
  • Flexible configuration: TTL support, custom key prefixes, index naming, metadata field indexing
  • Schema initialization: Automatic Redis index creation with configurable schema

Modules Added

  • memory/repository/spring-ai-model-chat-memory-repository-redis/ - Core implementation
  • auto-configurations/models/chat/memory/spring-ai-autoconfigure-model-chat-memory-redis/ - Auto-configuration

Test Plan

  • Unit tests for configuration classes
  • Integration tests with Redis Stack (Testcontainers)
  • Tests for message type handling (User, Assistant, System, Tool)
  • Tests for media content support
  • Tests for error handling and edge cases
  • Tests for advanced query capabilities
