I've improved the pinecone.py file by:
Updated from the deprecated PineconeGRPC client to the newer Pinecone client
Modified the client initialization code to match the new API requirements
Added better response handling with getattr() to safely access attributes from response objects
Removed the streaming_upsert method which is not available in the newer client
Added safer attribute access with fallbacks throughout the code
Updated the close method to reflect that the newer client doesn't need explicit closing
These changes ensure the code is compatible with the latest Pinecone Python SDK and will be more robust against future changes. The key improvement is migrating away from the deprecated gRPC client which will eventually stop working.
• Removed the unused Pinecone REST‐client import; we now only import ServerlessSpec and the gRPC client.
• Enhanced close()
• Call self.client.close() to explicitly shut down the underlying gRPC channel.
• Log success or a warning on failure.
• Still tear down the thread‐pool executor afterward.
• Context‐manager support
• Added __enter__()/__exit__() so you can do:
with PineconeClient() as client:
client.insert(...)
# automatically calls client.close()
Now supports batched insert, upsert, and delete operations using a default batch size of 100, reducing API strain and improving throughput. All blocking calls to the Pinecone API are wrapped in asyncio.to_thread(...), ensuring async safety and preventing event loop blocking. The implementation includes zero-vector handling for efficient metadata-only queries, normalized cosine distance scores for accurate ranking, and protections against empty input operations. Logs for batch durations have been streamlined to minimize noise, while preserving key info-level success logs.
- Created `VectorDBBase` as an abstract base class to standardize vector database operations.
- Added required methods for common vector database operations: `has_collection`, `delete_collection`, `insert`, `upsert`, `search`, `query`, `get`, `delete`, `reset`.
- The base class can now be extended by any vector database implementation (e.g., Qdrant, Pinecone) to ensure a consistent API across different database systems.
Adds Pinecone as a supported vector database option.
- Implements `PineconeClient` with support for common operations: `add`, `query`, `delete`, `reset`.
- Emulates namespace support using metadata filtering (`collection_name` prefix).
- Dynamically configures Pinecone via the following env vars:
- `PINECONE_API_KEY`
- `PINECONE_ENVIRONMENT`
- `PINECONE_INDEX_NAME`
- `PINECONE_DIMENSION`
- `PINECONE_METRIC`
- `PINECONE_CLOUD`
- Integrates cleanly with the vector DB abstraction layer.
- Includes markdown documentation under `docs/getting-started/env-configuration.md`.
