Reading Time: 8 minutesMyISAM is a table-locking based engine. Table-locking prevents all other processes from writing data to the target table. This locking behavior encompasses the entire MyISAM table, no matter how minor the datachange. This type of locking preserves the integrity of the data but at the cost of performance. The performance penalty for using table-locking based engines like MyISAM become more laborious as the row count in the table grows. Very large tables will see a significant delay in performance when data needs to be written to a MyISAM table. Continue reading “MySQL Performance: MyISAM” →
