ahrtr	e155e50886	rename LockWithoutHook to LockOutsideApply and add LockInsideApply	2022-04-07 05:35:13 +08:00
ahrtr	bfd5170f66	add a txPostLockHook into the backend ... Previously the SetConsistentIndex() is called during the apply workflow, but it's outside the db transaction. If a commit happens between SetConsistentIndex and the following apply workflow, and etcd crashes for whatever reason right after the commit, then etcd commits an incomplete transaction to db. Eventually etcd runs into the data inconsistency issue. In this commit, we move the SetConsistentIndex into a txPostLockHook, so it will be executed inside the transaction lock.	2022-04-07 05:35:13 +08:00
