Announcing the release of Spice v1.11.5! 🛠️
Spice v1.11.5 is a patch release improving on_zero_results: use_source fallback performance, Delta Lake timestamp predicate data skipping, S3 Parquet read performance, PostgreSQL partitioned table support, Cayenne target file size handling, and preparing the CLI for v2.0 runtime upgrades.
on_zero_results: use_source Fallback Performance ImprovementImproved the on_zero_results: use_source (opens in a new tab) fallback path to run DataFusion's physical optimizer on the federated scan plan (#9927 (opens in a new tab)). The fallback path now runs SessionState::physical_optimizers() rules on the federated scan plan before execution, enabling parallel file group scanning and other optimizations. This results in significantly faster fallback queries on multi-core machines, particularly for file-based data sources like Delta Lake.
>= Timestamp PredicatesDelta Lake (opens in a new tab) table scans with >= timestamp filters now correctly prune files that do not match the predicate (#9932 (opens in a new tab)), improving query performance through more effective data skipping (file-level pruning).
The PostgreSQL (opens in a new tab) data connector now supports partitioned tables (opens in a new tab) (#9997 (opens in a new tab)) for both federated and accelerated queries.
Improved parquet read performance from S3 (opens in a new tab) and other object stores (#10064 (opens in a new tab)), particularly for tables with many columns. Column data ranges are now coalesced into fewer, larger requests instead of being fetched individually, reducing the number of HTTP round-trips.
The Cayenne (opens in a new tab) accelerator now correctly respects the configured target file size (#10071 (opens in a new tab)). Previously, Cayenne could produce many small, fragmented Vortex files; with this fix, files are written at the expected target size, improving storage efficiency and query performance.
The Spice CLI can now upgrade to v2.0 runtime versions. This enables upgrading to v2.0 release candidates and, once released, the v2.0 stable runtime.
Running spice upgrade without a version will upgrade to the latest stable version, including v2.0 once released.
Note: Native Windows runtime builds will no longer be provided in v2.0. Use WSL (opens in a new tab) for local development instead.
No breaking changes.
No new cookbook recipes.
The Spice Cookbook (opens in a new tab) includes 86 recipes to help you get started with Spice quickly and easily.
