MariaDB take long time to execute

问题

I have a table with 500 rows of data in "MariaDB-10.3.1"

When i run "TURNUCATE, ALTER, DROP, RENAME" operations take a long time for execution and nothing happend, i wait 30 minutes for 500 rows of data but not finished execution.

anyone can help me to solve the problem?

回答1:

I use

SELECT concat('KILL ', ID, ';') FROM INFORMATION_SCHEMA.PROCESSLIST WHERE `db` IN (DATABASE_NAMES);

and kill all process then my query worked.

Thank you all.
