What's wrong with this SQL LOCK WAIT timeout killing requests?
What's wrong with this SQL LOCK WAIT timeout killing requests. The SQL code has default innodb_lock_wait_timeout. In MySQL long held locks cause others to fail. In SQL tune or fix the long transactions.

Why does this SQL lock table block readers?
