Changelog

Noteworthy milestones from across the Hotdata platform.

October 2026

  • SQL writes on the query endpoint

    INSERT, CREATE TABLE, CREATE TABLE AS SELECT, and DROP TABLE run straight from SQL.

  • One-line CLI install

    curl -fsSL https://hotdata.dev/install | sh

  • The integration wave, part two

    Ibis, LangChain, dlt, and Tenki guides, plus why we built on LiquidCache. Read more →

September 2026

  • IVF vector indexes

    Index tables too large for HNSW; memory follows what a search reads, not table size.

  • Database lineage

    See a database's fork family tree, from the API or hotdata databases lineage.

  • 16 GiB uploads

    Load Parquet, CSV, or NDJSON files up to 16 GiB each from the Python and Rust clients or the CLI.

August 2026

  • Docs restructure

    Docs reorganized into Core Concepts, Push Data, and Pull Data.

  • Benchmarks page

    Hotdata's benchmark results, side by side with the systems it was compared against. Read more →

July 2026

  • Fork a database

    Instant server-side copy of a managed database — branch your data like you branch code.

  • Mutable managed tables

    Append, upsert, and keyed deletes, plus Chain to materialize query results into tables.

  • Concurrency benchmark published

    Query latency stays flat from 1 to 50 readers, compared against Snowflake and BigQuery. Read more →

June 2026

  • datafusion-ducklake open-sourced

    DuckLake support for Apache DataFusion, donated to datafusion-contrib; now Hotdata's storage backend. Read more →

  • Rust SDK published

    The hotdata crate, with Arrow decoding and resumable uploads.

  • Direct-to-storage uploads

    Files stream in resumable chunks, so any size table loads from any machine.

May 2026

  • Managed databases launch

    Create in under a second, load Parquet, query; auto-expiry makes throwaway databases practical.

  • The integration wave

    Ibis, marimo, LangChain, LlamaIndex, Jupyter, and the dlt destination.

  • Arrow-native results

    Results stream as Arrow IPC, plus CSV, Markdown, and Parquet formats.

April 2026

  • Semantic search with automatic embeddings

    vector_search() embeds your query text for you. Read more →

  • Python SDK published

    pip install hotdata.

March 2026

  • The Hotdata CLI launches

    Auth, workspaces, and SQL from the terminal, via Homebrew.

  • Full-text and vector search

    BM25 and HNSW indexes, queryable in plain SQL.

  • Public API, formalized

    OpenAPI spec with browsable reference docs.

February 2026

  • hotdata.dev goes live

    Company site, docs, and blog.

  • Geospatial SQL

    PostGIS-style ST_* functions and GeoParquet output.

January 2026

  • Smart caching layer lands in the engine

    The foundation of Hotdata's sub-second queries.

  • Query results become data

    Every result is saved and queryable with SQL.
