R2 Data Catalog Table Maintenance, Now Fully Visible in the Dashboard!

Cloudflare Changelog ★★★ View Markdown
#cloudflare#infrastructure#devops

Hey everyone, it's Shiichan! Today I've got a quiet but handy update for anyone using R2 Data Catalog!

Cloudflare Changelog developers.cloudflare.com

What was announced?

On the Cloudflare Changelog, they announced that R2 Data Catalog now provides table-level maintenance visibility and manual compaction queueing in the dashboard.

Why it matters

R2 Data Catalog manages Iceberg-format tables, but until now there wasn't much of a way to see when maintenance tasks like compaction or snapshot expiration were eligible to run, or to review what maintenance had already happened. Without a clear view of table state, it's hard for operators to judge when cleanup is needed.

What changes

You can now check a table's maintenance status without leaving the dashboard. Here's how.

  • In the Cloudflare dashboard, go to R2 Data Catalog
  • Select a catalog, then open the Explorer tab (which opens by default)
  • Select the table you're interested in
  • Select the Maintenance tab

Dive Deep

The updated dashboard adds several pieces.

  • Maintenance tab: View compaction and snapshot expiration settings, schedules, and next eligibility, alongside the existing Schema and Metadata tabs
  • Recent runs: A paginated audit log of job status and duration, with expandable rows for manifest rewrites, compaction, and snapshot expiration, including operation metrics for each
  • Manual queueing: Selecting "Queue maintenance" requests compaction during the next normal scheduler poll. It checks permissions and tells you when another maintenance job conflicts or the daily accepted-request limit has been reached
  • Updated catalog layout: Catalog metrics move to a Metrics tab, browsing happens in the renamed Explorer tab, and switching between table details now uses tabs instead of a scroll-to-section sidebar
  • Improved schema browser: For accounts with the schema browser enabled, selecting a namespace opens its tables in the right pane

Wrap-up

  • R2 Data Catalog's dashboard now has table-level maintenance visibility
  • The Maintenance tab shows settings, schedules, and next run timing, while Recent runs lets you audit past executions
  • You can manually request compaction via Queue maintenance, with permission and conflict checks plus a daily limit check
  • The catalog's overall layout was also reorganized, with an Explorer tab and tab-based table details

This is a great fit if you run Iceberg tables on R2 Data Catalog and want to keep a close eye on table maintenance!
