ae274a3e6d* Refactor vectorstore components structure Moved vectorstore components for Chroma, ClickHouse, Couchbase, DataStax, Elastic, Milvus, MongoDB, Pinecone, Qdrant, Supabase, Upstash, Vectara, and Weaviate into dedicated subfolders with __init__.py files for each. Updated Redis vectorstore implementation to reside in redis.py and removed the old vectorstores/redis.py. Adjusted starter project JSONs and frontend constants to reflect new module paths and sidebar entries for these vectorstores. * Refactor vectorstore components and add lazy imports Moved Datastax-related files from vectorstores to a dedicated datastax directory. Added lazy import logic to __init__.py files for chroma, clickhouse, couchbase, elastic, milvus, mongodb, pinecone, qdrant, supabase, upstash, vectara, and weaviate components. Cleaned up vectorstores/__init__.py to only include local and faiss components, improving modularity and import efficiency. * [autofix.ci] apply automated fixes * Refactor vectorstore components structure Moved FAISS, Cassandra, and pgvector components to dedicated subdirectories with lazy-loading __init__.py files. Updated imports and references throughout the backend and frontend to reflect new locations. Removed obsolete datastax Cassandra component. Added new sidebar bundle entries for FAISS, Cassandra, and pgvector in frontend constants and style utilities. * Add lazy imports and Redis chat memory component Refactored the Redis module to support lazy imports for RedisIndexChatMemory and RedisVectorStoreComponent, improving import efficiency. Added a new redis_chat.py file implementing RedisIndexChatMemory for chat message storage and retrieval using Redis. * Fix vector store astra imports * Revert package lock changes * More test fixes * Update test_vector_store_rag.py * Update test_dynamic_imports.py * Update vector_store_rag.py * Update test_dynamic_imports.py * Refactor the cassandra chat component * Fix frontend tests for bundle * Mark Local DB as legacy * Update inputComponent.spec.ts * [autofix.ci] apply automated fixes --------- Co-authored-by: autofix-ci[bot] <114827586+autofix-ci[bot]@users.noreply.github.com> Co-authored-by: Eric Hare <ericrhare@gmail.com> Co-authored-by: Carlos Coelho <80289056+carlosrcoelho@users.noreply.github.com> |
