\Zend\Db\Metadata\Metadata slow on MySQL

Question

Retrieving metadata from a table ( getConstraints() or getColumns() ) using Zend Framework 2 with MySQL is terribly slow. Is there a solution?

Answer 1

Mysql is terribly slow retrieving data from information schema. One solution is disabling stats on metadata by modifyng 'my.cfn'

innodb_stats_on_metadata=0

You can do this in the config file or dynamically:

mysql> set global innodb_stats_on_metadata=0;

Slow query on information_schema.tables
