What's Changed

Changed

  • SFTP write() / write_atomic() cut per-operation metadata round-trips (BK-313): the SFTP write path drops the redundant stat round-trips raw paramiko skips, and no longer returns a last_modified on WriteResult (WriteResult.size is unaffected). See the migration guide.

Fixed

  • SFTP failure paths on non-OpenSSH servers map to precise error types (BK-316): PermissionDenied / NotFound / InvalidPath instead of a generic RemoteStoreError, and interrupted atomic writes no longer leave temp-file litter. except RemoteStoreError still catches them; see the migration guide.
  • GraphBackend.check_health() probes the drive (BUG-231): ping() can now fail when the Graph drive is unreachable.
  • pyarrow<25 cap lifted from the arrow and sql-query extras (BUG-232): every pyarrow extra now aligns on an unbounded pyarrow>=12.0.0, closing a standalone-extra version split.

Documentation

  • Benchmark overhead presented as measured values, not a verdict (ID-230), and shown in absolute milliseconds with a raw+overhead decomposition chart (BK-314), correcting the "overhead shrinks as a share" narrative to the round-trip-count mechanism.
  • Backend-enumeration order pinned in the add-a-backend checklist (BK-310), and tagline / backend-membership mirrors synced (BK-311).
