In subsequent versions, JuiceFS has added a mechanism for automatic GC of TiKV.

If you’re still concerned, you can add an additional TiDB node… :upside_down_face:

But what I mean is, I’m not using it on JuiceFS. If I deploy it separately and use TiKV with the SDK, there will be no GC, right?

The triggering of this GC is a client interface.

As long as you use the official client, just call it directly and you’re done.

The person above is right, you can also use tikv-cli to handle it manually…
