🎨 Semantic.Art

Meet semantic.art, a multi-feature multi-index retrieval art discovery engine that lets you search with a feeling or intent rather than matching keywords.

Powered by LanceDB. The core of the system involves dynamically understanding and inspecting a query's intent. It then chooses the best search path on the fly, blending vector, FTS, hybrid search, filtering, and custom rerankers.

💾 Lance File 2.1 Is Now Stable

Big news from the LanceDB team — Lance File Format 2.1 is officially stable!

This release solves one of the biggest challenges from 2.0: 👉 adding compression without sacrificing random access performance.

🌟 Open Source Releases Spotlight

Feature Version Description
LanceDB 0.22.2 Allow bitmap indexes on large-string, binary, large-binary, and bitmap, support namespace database in Rust.
Lance 0.38.3 Support multi-base write, allowing one Lance dataset to span across multiple buckets. Support zstd/lz4 compression. Support custom stop word in FTS index. Support shallow clone and branching in Python and Java. Support Blob API in Java. Support index against nested field. Support change data feed for inserted and updated rows. Better logging and auditing across code execution.
0.38.2 Fix forward compatibility of FTS index changes in 0.38.0.
0.38.1 Support fragment level column update. Support faster IVF-PQ indexing on GPU.
0.38.0 ❗ As of this release, the 2.1 version of the file format is considered stable. There will be no more breaking changes and the format should be readable by future versions of Lance. In an upcoming release, the 2.1 version will become the default.

Blob encoding for v2.1 file format. Performance improvement of FTS index (reduces P95 latency by 32.3%). FTS index now supports specialized JSON document tokenizer.
Lance Namespace 0.0.17–0.0.20 Add support for Azure OneLake, refactor of Rust library into main Lance repo for better integration.
Lance Ray 0.0.7–0.0.8 Support distributed compaction of Lance table.
Lance Spark 0.0.14–0.0.15 Data Evolution in Apache Spark: users can run ALTER COLUMN FROM to add a column and backfill data simultaneously.
