Hi, Now Iam trying to migrate from MySQL to MariaDB. Why does the TRUNCATE TABLE statement hang sometimes? What are the reasons for this type of issue? This problem doesn't happen with MySQL, only with MariaDB. The hanging statement is simply: TRUNCATE TABLE sampledb.datatable; What can cause this to happen, and how could I fix it? Another one observation is if the table have some data, may be one or two rows, then the truncate query works successfully. Else the table have a lot of data, query becomes hang. If the same table have more than one connetion, then the truncate table query hangs. How I fix it??? Now Iam blocking. Engine I selected is MyISAM.
What MySQL version you migrate from, and what MariaDB version you migrate to? What does SHOW PROCESSLIST say, what the hanged connection is doing? Regards, Sergei
