Does TiDB support minority quorum recovery and then recover using PITR logs? For example, with 3 replica TiKV, if 2 replicas are lost, can the single remaining minority replica be forcibly recovered using PITR logs?

In general, the minority’s data is incomplete, and it may not even have a leader replica.

Unsafe recover, there is documentation in the community… It’s equivalent to abnormal recovery and will result in the loss of the latest data.
