Announcing the release of Spice v1.7.1! 🔍
Spice v1.7.1 is a patch release focused on search improvements, bug fixes, and performance enhancements. This release introduces the Reciprocal Rank Fusion (RRF) user-defined table function (UDTF) for hybrid search, improves vector and text search reliability, and resolves several issues across the runtime, connectors, and query engine.
Reciprocal Rank Fusion (RRF) UDTF: Spice now supports Reciprocal Rank Fusion (RRF) as a user-defined table function, enabling advanced hybrid search scenarios that combine results from multiple search methods (e.g., vector and text search) for improved relevance ranking.
Features:
vector_search, text_search, and other search UDTFs in a single query.Example usage:
Learn more in the RRF documentation.
Acceleration Refresh Metrics: Spice now exposes additional Prometheus metrics that provide detailed observability into dataset acceleration refreshes. These metrics help monitor data freshness and ingestion lag for accelerated datasets with a time column.
Reported metrics:
| Metric Name | Description |
|---|---|
dataset_acceleration_max_timestamp_before_refresh_ms | Maximum value of the dataset's time column before refresh (milliseconds). |
dataset_acceleration_max_timestamp_after_refresh_ms | Maximum value of the dataset's time column after refresh (milliseconds). |
dataset_acceleration_refresh_lag_ms | Difference between max timestamp after and before refresh (milliseconds). |
dataset_acceleration_ingestion_lag_ms | Lag between current wall-clock time and max timestamp after refresh (milliseconds). |
These metrics are emitted during each acceleration refresh and can be scraped by Prometheus for monitoring and alerting. For more details, see the Observability documentation.
This release resolves several issues and improves reliability across search, connectors, and query planning:
