Spice v2.0.1 is now available! 🛠️

Spice v2.0.1 is a patch release focused on reliability and performance. It speeds up Apache Iceberg reads and fixes bugs across AWS S3 and object-store datasets, data acceleration, distributed query, and authenticated access.

What's New in v2.0.1

Faster Iceberg Reads with Parallel File Scanning

The Apache Iceberg (opens in a new tab) reader now scans data files in parallel (#11331 (opens in a new tab)), improving read throughput and latency for Iceberg tables that span many files.

AWS S3 & Object-Store Reliability

Three fixes improve S3 (opens in a new tab) and object-store dataset behavior:

• Refresh-skip restored (#11339 (opens in a new tab)): ETag/Version-based refresh-skip works reliably again, so unchanged S3 objects are no longer re-downloaded on every refresh.
• Retry when source files are not yet available (#11342 (opens in a new tab)): an object-store dataset whose source files are not present at startup now retries and becomes ready once the data appears, instead of failing permanently.
• Path-style addressing for dotted bucket names (#11347 (opens in a new tab)): on standard AWS, buckets whose names contain dots now default to path-style addressing, avoiding TLS wildcard certificate errors under virtual-hosted-style HTTPS.

Data Acceleration & Distributed Query Fixes

Two fixes ensure accelerated (opens in a new tab) datasets behave correctly in more configurations:

• Acceleration endpoints (#11345 (opens in a new tab)): /v1/datasets/{name}/acceleration/refresh (and the related update-refresh-sql, partition-filters, and snapshots endpoints) now work for all accelerated datasets, fixing cases where some incorrectly reported Table is not accelerated.
• Distributed clusters (#11226 (opens in a new tab)): the distributed query (opens in a new tab) coordinator now serves accelerated data from executors for all accelerated datasets, instead of falling back to reading from the source for some.

Authenticated Query Fixes

With authentication enabled, queries now consistently run as the requesting user (#11253 (opens in a new tab)), so per-user behavior such as results caching is correctly scoped to each user.
