Re: Lock wait timeout exceeded; try restarting transaction error - do I need a different index?

5k values with those three value pairs, that's an index selectivity problem.

Row constructor syntax doesn't always yield optimal index use. Did you try it without the row constructor? What is the Explain result on the query with and without the row constructor?

MySQL version? What is innodb_buffer_pool_size? RAM?
