What is slow query in MySQL?
The slow query log consists of SQL statements that take more than long_query_time seconds to execute and require at least min_examined_row_limit rows to be examined. The slow query log can be used to find queries that take a long time to execute and are therefore candidates for optimization.
Why is my MySQL query running slow?
There are a number of things that may cause a query to take longer time to execute: Inefficient query – Use non-indexed columns while lookup or joining, thus MySQL takes longer time to match the condition. Table lock – The table is locked, by global lock or explicit table lock when the query is trying to access it.
