Highlights include experimental Table Branching & Tags for data version control, full Spatial Index support for Geometry/Geography workloads, and newly live Iceberg Write support (via iceberg-rust v0.8.0). Engine improvements include self-join elimination, lazy materialization across joins, and Fuse Parquet Prewhere optimizations, alongside Meta service observability and Openraft upgrades. A spotlight section frames Table Branching as a safe sandbox for AI agents to experiment on data without touching production tables. ## Full article daily.dev links to this article rather than hosting it. Read it at the original source: ## Questions this post answers ### What is Table Branching and Tags in Databend used for? Table Branching and Tags is an experimental Databend feature enabling data version control by letting users create branches of a table for safe experimentation. Agents or users can perform DELETE, UPDATE, or complex ETL operations on a branch without affecting the main table, then merge verified changes back or use tags for snapshot-based rollback via time travel. _Teams evaluating data version control workflows can follow Databend's evolving feature set on daily.dev._ ### Does Databend support writing to Iceberg tables? Yes, Databend added Iceberg write support by upgrading to iceberg-rust v0.8.0, enabling the write path in addition to existing read support and improving compatibility with open data lake formats. This was delivered as part of a run of 11 nightly releases spanning versions v1.2.863 through v1.2.873. _Developers weighing lakehouse write compatibility across engines can track updates like this on daily.dev._ ### What spatial indexing capabilities does Databend offer for Geometry and Geography data? Databend introduced Spatial Index support with CREATE/DROP SPATIAL INDEX statements that fully cover Geometry and Geography workloads, boosting spatial query performance. This was shipped alongside other query engine improvements like self-join elimination and lazy materialization across joins during the same nightly release cycle. _Engineers building geospatial analytics pipelines can follow database feature rollouts like this on daily.dev._ ## Similar posts on daily.dev - [Announcing Apache Iceberg 1.11.0](https://daily.dev/posts/announcing-apache-iceberg-1-11-0-laq8a21od) · Google Open Source Blog · 4 upvotes · 0 comments - [Geospatial Unbounded: Spatial SQL GA with AI/BI Maps, Delta Sharing, and Iceberg v3](https://daily.dev/posts/geospatial-unbounded-spatial-sql-ga-with-ai-bi-maps-delta-sharing-and-iceberg-v3-ta19gry1t) · databricks · 0 upvotes · 0 comments - [Apache Iceberg 1.12 and Rust 0.11: What's New](https://daily.dev/posts/apache-iceberg-1-12-and-rust-0-11-what-s-new-zfzjpbdok) · Dremio Blog · 14 upvotes · 1 comments - [Dynamic Tables Just Got Faster and Far More Flexible — PART 2](https://daily.dev/posts/dynamic-tables-just-got-faster-and-far-more-flexible-part-2-vhlaaaocj) · Snowflake Community · 0 upvotes · 0 comments --- Tags: [#backend](https://daily.dev/tags/backend), [#data-warehouse](https://daily.dev/tags/data-warehouse), [#apache-iceberg](https://daily.dev/tags/apache-iceberg) [View this post on daily.dev](https://daily.dev/posts/databend-monthly-report-january-2026-table-branching-tags-spatial-indexes-chhbxcsw9) ```json {"@context":"https://schema.org","@graph":[{"@type":"Organization","@id":"https://daily.dev/#organization","name":"daily.dev","url":"https://daily.dev","logo":{"@type":"ImageObject","url":"https://daily.dev/apple-touch-icon.png","width":180,"height":180},"sameAs":["https://twitter.com/dailydotdev","https://github.com/dailydotdev","https://www.linkedin.com/company/daily-dev-ltd"]},{"@type":"WebSite","@id":"https://daily.dev/#website","url":"https://daily.dev","name":"daily.dev","publisher":{"@id":"https://daily.dev/#organization"},"potentialAction":{"@type":"SearchAction","target":{"@type":"EntryPoint","urlTemplate":"https://daily.dev/search?q={search_term_string}"},"query-input":"required name=search_term_string"}}]} {"@context":"https://schema.org","@type":"TechArticle","headline":"Databend Monthly Report: January 2026 — Table Branching & Tags, Spatial Indexes","url":"https://daily.dev/posts/databend-monthly-report-january-2026-table-branching-tags-spatial-indexes-chhbxcsw9","mainEntityOfPage":{"@type":"WebPage","@id":"https://daily.dev/posts/databend-monthly-report-january-2026-table-branching-tags-spatial-indexes-chhbxcsw9"},"datePublished":"2026-08-16T08:53:59.903Z","dateModified":"2026-08-16T08:57:46.316Z","description":"Databend's January monthly report covers 11 nightly releases (v1.2.863 to v1.2.873-nightly) with 33 new features, 31 bug fixes, and 37 refactors.
