Then you should update the DuckDB documentation, which currently states that for the DuckDB format AIO shall be implemented in the future, not in the current release.

The release announcement links to several pages from a few months ago, like:

https://duckdb.org/2026/07/31/asynchronous-io

which according to you are no longer true.

EDIT:

Today I see in the release announcement "DuckDB 2.0 introduces asynchronous I/O for reading Parquet and CSV files, as well as DuckDB's native storage format. "

So it seems that the announcement has been updated, because I am pretty sure that yesterday the ending of this sentence did not exist.

Great, thanks! Also since 2.0 or earlier? I somehow struggle to find docs for it.
