Floe

Floe is a policy-based table maintenance system for Apache Iceberg.

Floe automates table maintenance through declarative policies:

• Compact small files for better query performance
• Expire old snapshots to reclaim storage
• Remove orphan files not referenced by any snapshot
• Optimize manifests for faster query planning

Floe orchestrates maintenance operations that wrap around Iceberg's maintenance procedures.
