🎤 Catch Us on Stage This June!

We’re thrilled to be speaking at several top-tier events this month — alongside our customers — sharing real-world insights from scaling enterprise AI systems in production.

If you’re attending the AI Engineering World Fair (June 3–5), Data + AI Summit (June 9–12), or the Toronto Machine Learning Summit (June 13–18), don’t miss our sessions across multiple tracks. Come say hi and learn what we’ve been building!


⚙️ Lance Format Deep Dives

In addition to our highly requested deep dives into the Lance format, we also shared our perspective on the future of open source table formats — inspired by feedback and questions from the Iceberg community.

Columnar File Readers in Depth: Column Shredding
Record shredding is a classic method used to transpose rows of potentially nested data into a flattened tree of buffers that can be written to the file. A similar technique, cascaded encoding, has recently emerged, that converts those arrays into a flattened tree of compressed buffers. In this article we
Columnar File Readers in Depth: Repetition & Definition Levels
Repetition and definition levels are a method of converting structural arrays into a set of buffers. The approach was made popular in Parquet and is one of the key ways Parquet, ORC, and Arrow differ. In this blog I will explain how they work by contrasting them with validity & offsets
The Future of Open Source Table Formats: Apache Iceberg and Lance
As the scale of data continues to grow, open-source table formats have become essential for efficient data lake management. Apache Iceberg has emerged as a leader in this space, while new formats like Lance are introducing optimizations for specific workloads. In this post, we’ll explore how Iceberg and Lance

🎥 Event Recap: AI at Scale with Samsara

The Samsara team is harnessing LanceDB to simplify and streamline AI data infrastructure for massive, real-world datasets.

In May, our cofounder Chang She joined Samsara’s AI Speaker Series, where he shared cutting-edge insights on multimodal AI and the evolving landscape of AI agents.

🔐 LanceDB Enterprise Product News

  • Smoother concurrent upserts: Upsert operations are now conflict-free in typical workloads, so you can write without worrying about collisions.
  • Significantly reduced storage costs: Reduce object store operations by up to 95% with small files loaded with a single I/O instead of multiple IOPS - ideal for small-table workloads.
  • Filter binary data with ease: Now query large binary columns directly in your filters – no workarounds needed.
  • Optimized GCP deployment tuning: Fine-tune weak consistency and concurrency limits to better balance performance, cost, and flexibility.
  • Intuitive embedding visualization: New UMAP visualizations help you explore and understand vector data at a glance.

🛠️ Open Source Releases Spotlight 

  • Boolean logic for full-text search: Combine filters with AND/OR or &/| — full-text search now works the way you think.
fts_query = MatchQuery("puppy", "text") & MatchQuery("happy", "text")
  • Faster, smarter full-text indexing: Compression and optimized search algorithms speed up index builds and boost performance at scale.
  • No more stalled upserts: A new timeout setting ensures merge_insert operations won’t hang forever.
table.merge_insert(id)
        .when_matched_update_all()
        .when_not_matched_insert_all()
        .execute(new_data, timeout=timedelta(seconds=10))
    )
  • Flexible phrase matching: Control how loose or tight your matches are with the slop parameter.
 fts_query=PhraseQuery("frodo was happy", "text", slop=2)
  • Spark compatibility built in: Works with multiple Spark versions out of the box — just drop in the bundled JAR and go. Quick start
