For the 'Block' example of using a replica node, a write operation fails and raft exits #493
Description
usage mode
I use the Block example. In the block example, the original data is written to a file. I write the original data to the storage engine.
Discovered problems
A data failed to be written to engine in 'on_apply()' function. The response was set to 'false'. Then Raft began to switch the Leader, but since it was 1 repliac, the switch failed. Finally, Raft exits. In the above situation, after the attempt to switch the leader fails, Raft should not exit, and the subsequent data should still be able to continue being written. If I want to achieve such a way, what should I do?
