When we use secondary mode, the wal or sst file may not found.

Is it possible to add wal or sst to delay deletion?

Expected behavior

catchup success

Actual behavior

catchup fail，file not found

Steps to reproduce the behavior

I think you should call TryCatchupWithPrimary() in an enough frequency to for proper data synchronization. WAL is selected for deletion in primary regardless of the secondary

the secondary instance requires you to actively call refresh
