Overview

The DuckDB project is governed by the non-profit DuckDB Foundation. The Foundation and DuckDB Labs are not funded by external investors (e.g., venture capital). Instead, the Foundation is funded by contributions from its members, while DuckDB Labs' revenue is based on commercial support and feature prioritization services.

Planned Features (Last Updated: June 2025)

This section lists the features that the DuckDB team plans to work on in the coming year.

• Documentation for the C extension API
• Generic ODBC catalog, similarly to the existing PostgreSQL / MySQL / SQLite integrations
• Go and Rust support for extensions
• Data lake formats
  • Improved support for the Iceberg format through the iceberg extension
  • Improved support for Delta Lake through the delta extension
  • Note that we released DuckLake, a lakehouse format, in May 2025. We would like to emphasize that we are still committed to develop both DuckDB's Iceberg and Delta Lake extensions, including adding write support for these formats. Upcoming releases of DuckDB will be therefore capable of converting data lakes between these formats, i.e., importing to DuckLake and exporting from DuckLake to another data lake format.
• MATCH RECOGNIZE for pattern matching
• Remote file content caching using buffer manager (e.g., when querying Parquet files on S3)
• Database file encryption
• Distribution of musl libc binaries

This list was compiled by the DuckDB maintainers and is based on the long-term strategic vision for the DuckDB project and general interactions with users in the open-source community (GitHub Issues and Discussions, social media, etc.). For details on how to request features in DuckDB, please refer to the FAQ item “I would like feature X to be implemented in DuckDB”.

Please note that there are no guarantees that a particular feature will be released within the next year. Everything on this page is subject to change without notice.
