Cobble 0.5.3 improves storage compatibility and metadata reliability.

Highlights

  • Safer metadata updates: Support storage without atomic rename, while retaining native atomic replacement on local filesystems, including Windows.
  • Improved storage URLs: Fix backend-specific path and credential handling, including HDFS URLs and IPv6 endpoints.
  • More reliable cleanup: Fix directory listing, missing-file handling, compaction lease cleanup, and temporary metadata discovery.

Upgrade Notes

  • Cobble 0.5.3 can read Cobble 0.5.2 data and snapshots; no data migration is required.
  • Alluxio support and the storage-alluxio feature have been removed.
  • FileCatalog::load_shard_schema_mapping has been removed; shard schema mappings are now maintained in memory.
