## containers Table 

The containers  table is the most important of the three configuration tables. Each InnoDB  table that is used to store memcached  values must have an entry in the containers  table. The entry provides a mapping between InnoDB  table columns and container table columns, which is required for memcached  to work with InnoDB  tables. 

The containers  table contains a default entry for the test.demo_test  table, which is created by the innodb_memcached_config.sql  configuration script. To use the daemon_memcached  plugin with your own InnoDB  table, you must create an entry in the containers  table.
