Durable Objects Storage Growth Is Now Fully Visible!

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

Hi, it's Shiichan! Today I've got a small but handy update for anyone running Durable Objects.

Cloudflare Changelog developers.cloudflare.com

What was announced?

Cloudflare's Changelog announced that you can now see the total SQLite storage used by a Durable Object namespace right in the dashboard. The new Total storage chart shows the maximum storage reported during each hour, plotted over time. You'll find it in the Durable Objects section of the Cloudflare dashboard.

The story so far

Until now, there wasn't an easy way to check how much storage a namespace was accumulating directly from the dashboard. Figuring out whether storage was quietly creeping up, whether a cleanup job actually worked, or whether something was using more storage than expected required digging elsewhere.

What changes

With the Total storage chart, you can track a namespace's storage over time and:

  • Watch for growth trends to catch storage creeping up before it becomes a problem
  • Confirm that a data cleanup job actually reduced storage afterward
  • Spot unexpected storage growth and start investigating the cause

If you run a lot of Durable Objects, being able to see "how much has piled up right now" at a glance is a nice win.

Dive Deep

The chart only appears for Durable Object namespaces backed by SQLite. It won't show up for namespaces still using the legacy key-value storage backend.

Also, this only shows the aggregate total for the whole namespace. You still can't filter down to a single Durable Object by ID or name to see its individual storage usage. For more details, check the Metrics and analytics docs.

Wrap-up

  • Cloudflare's dashboard now has a Total storage chart for Durable Objects
  • It shows the maximum storage reported each hour, over time
  • Only available for SQLite-backed namespaces, not the legacy key-value backend
  • Per-object storage view by ID or name isn't supported yet

If you want to keep an eye on storage growth or verify your cleanup jobs are working, this update is for you!
