provisa-duckdb-ext
Pinned, per-platform DuckDB extension binaries for the Provisa embedded tier, delivered via PyPI.
Why this package exists
The extensions the embedded DuckDB engine loads (sqlite_scanner, iceberg, delta,
postgres_scanner, …) are not statically linked into the duckdb PyPI wheel — DuckDB fetches them
from extensions.duckdb.org at runtime. Behind an enterprise firewall where only PyPI/Maven/npm/NuGet
are proxied (Artifactory), that host is unreachable and the embedded tier breaks.
This package embeds the pinned, per-platform .duckdb_extension binaries as ordinary wheel data so
acquisition flows through PyPI instead. One universal wheel carries every platform. Provisa's
provisa.federation.duckdb_extensions.stage_bundled_extensions copies the running platform's blobs
into a writable directory on first run and points PROVISA_DUCKDB_EXT_DIR at it.
Extensions are locked to the exact DuckDB build they were mirrored from, so an incompatible duckdb
version can never silently load a mismatched extension.
This package is a dependency of Provisa's embedded tier — install provisa directly rather than this
package on its own.
