Announcing the release of Spice v1.9.1!🔥
v1.9.1 introduces Amazon Bedrock Nova 2 Multimodal embeddings support with high-dimensional vectors up to 3,072 dimensions and purpose-optimized embeddings for semantic search and retrieval operations, DynamoDB timestamp filter pushdown for more efficient append-mode acceleration with configurable time formatting, HTTP Data Connector health probe configuration for improved endpoint validation reliability, and Spice .NET SDK v0.2 with expanded .NET version support and updated gRPC libraries. This release focuses on bug fixes, stability, and performance improvements.
Spice now supports the Amazon Nova 2 Multimodal embeddings models via the Bedrock models provider, enabling high-quality text embeddings for semantic search and vector similarity operations. The Nova embeddings model offers configurable dimensions and advanced features like truncation modes and embedding purpose optimization.
Key Features:
START, END, or NONE)GENERIC_INDEX, GENERIC_RETRIEVAL, or CLASSIFICATION)Example spicepod.yml configuration:
For more details on the embedding parameters and configuration options, refer to the Amazon Nova Embeddings Documentation and the Spice Embeddings Documentation.
The DynamoDB Data Connector now supports timestamp filter pushdown, enabling more efficient append-mode acceleration refreshes by pushing timestamp filters directly to DynamoDB queries. Since DynamoDB stores timestamps as strings rather than native datetime types, this feature includes configurable timestamp formatting to ensure correct parsing and filtering.
Key Features:
Example spicepod.yml configuration:
For more details, refer to the DynamoDB Data Connector Documentation.
The HTTP Data Connector now supports configurable health probe paths for endpoint validation. Instead of using a random non-existent path, the system can now validate endpoints using a user-specified path, improving flexibility and reliability for health checks.
Example spicepod.yml configuration:
For more details, refer to the HTTP Data Connector Documentation.
The Spice .NET SDK has been upgraded with expanded .NET version support, custom User-Agent configuration, and updated gRPC libraries: spice-dotnet v0.2.0. The SDK is available on NuGet.
