- Delta Extension 10194
- The delta extension adds support for the Delta Lake open-source storage format . It is built using the Delta Kernel . The extension reads Delta tables, local and remote, and writes them: it can create tables and append to them. For implemen

The database holds exactly one table, with the same name as th...e database, so my_table and my_table.my_table refer to the same table: ATTACH 'file:///⟨path⟩' AS my_table (TYPE delta); SELECT * FROM my_table; Reading from an S3 Bucket To scan a Delta table in an S...a_scan('gs://⟨my_bucket⟩/⟨path⟩'); Creating Tables New This feature was introduced in DuckDB 2.0.

- Quack Remote Protocol 9017
- The Quack extension turns a DuckDB instance into a server that other DuckDB instances (clients) can connect to over HTTP. This page covers the protocol at a glance and walks through basic usage on both sides of the wire. For the full list o

- Connect 8385
- Overview Every DuckDB feature reachable from Java starts with a Connection . This page covers the JDBC URL forms the driver accepts, how DuckDB and driver options are passed and which of them win, how connections come to share (or not share

Opening a Connection In JDBC, database connections are c...explicitly as well: SET threads = 4; SET async_threads = 4; Two consequences are worth calling out for Java applications: Attached databases do not add threads.
