(Last updated: Oct 2026)

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”.

Planned Features

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

Coming Soon

• Stabilizing the C API v2 and the C extension API
• MATCH_RECOGNIZE for pattern matching – in flight for DuckDB 2.1
• Support for PL/SQL stored procedures (see Denis Hirn's DuckPL talk) – in flight for DuckDB 2.1

Major Features

• Rust support for extensions
• Go support for extensions
• Continuous improvements to support for lakehouse formats
• Materialized views
• Parallel Python UDFs
• macOS installer
• Windows installer

Other Features and Optimizations

• Time series optimizations
• Further partition-aware optimizations
• Sorting-aware optimizations
• Better filter cardinality estimation using automatically maintained table samples
• ALTER TABLE support for adding foreign keys
• XML read support
• Guaranteeing FIPS-compliance for the database encryption
• Improvements of query profiling (especially for concurrently running queries)
• Performance and out-of-core optimization on Windows

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.

Delivered in DuckDB 2.0

The following features from the previous version of the roadmap were released in DuckDB 2.0.0:

• Using the new PEG parser by default
• Shipping the polished version of the Quack protocol
• Support for async I/O
• C++17 support

Planned Deprecations

We are gradually phasing out some features:

• The lambda syntax (x -> x + 1) is deprecated in favor of the Pythonic lambda x : x + 1. DuckDB 1.5 throws a warning when using the deprecated syntax and DuckDB 2.0 throws an error (unless configured explicitly to allow the old syntax). DuckDB 2.1 will remove the old syntax completely.
• We are phasing out macOS x86_64 (osx_amd64) from the list of supported platforms. In DuckDB 2.0, DuckDB and core extensions are still built and supported for this platform, but community extensions are no longer built for it. DuckDB 2.1 will stop supporting osx_amd64.
