Description:
I've used InnoDB Memcached Plugin for version 5.6.

When I've describe in innodb_memcache.containers table fields described as UNSIGNED INT(10) DEFAULT 0 - it stores wrong integer value in memcached ( but key values used right values - I have next columns - `id`, `amount`, `locked` - all of them - UNSIGNED INT(10) DEFAULT 0, `id` is a primary auto_increment )

When I change column definition to INT(10) DEFAULT 0 ( I've mean signed ) - right integer values stored.

How to repeat:
see description.

ENUM also stores wrong values, for example:
in table:
`status` ENUM('canceled','finished','started') NOT NULL DEFAULT 'started',
in `containers` of `innodb_memcache`
`value_columns`='amount|status'
in fact from memcached:
250|-107
where 250 is correct, but -107 means 'finished'

Hi,

Thank you for your report.

We are not capable of repeating your test case as is. We would require the entire test case which should include:

* The setup of the MemCached Plugin
* Definitions of the tables
* The exact INSERT command
* The command that retrieves values from this Plugin

Thanks in advance.
