> [!NOTE]
> The Parquet metrics and DataFusion work in the source tree is an early prototype. It is not built into the v0.9.0 binaries or Docker images and is not a supported 0.9.0 feature.

> [!IMPORTANT]
> Before upgrading from 0.8.x, back up the metastore. Quickwit 0.9 migrates it on first write; rollback requires restoring that backup.
