Re: Need help for understanding why the MySQL allow to gap lock conflicting between two transactions.

Thanks for your reply, Peter.

But I still can't understand why MySQL allows conflicting gap locks.

What does mean this sentence?
"The reason conflicting gap locks are allowed is that if a record is purged from an index, the gap locks held on the record by different transactions must be merged."

Thanks in advance.
