I'm very excited about TiDB, but without this feature it's difficult to use.
Eagerly waiting for this. :smile:

We will not support this operation for the time being.
If we start to support, we will update the progress here.

[zimulala]

We haven't dealt with it yet, but we are already sorting out related issues and plans. If you are interested, you can also participate. We will provide related design documents in the near future.

Can someone please move this to higher priority since nearly every single codebase does this and it always errors out?

I am going to close this as a duplicate of https://github.com/pingcap/tidb/issues/14766

I realize this issue predates this, but #14766 is actively being worked on, and has a better break down of the sub-tasks involved. Thanks!
