The <info>%command.name%</info> command is meant to clear a second-level cache collection regions for an associated Entity Manager.
It is possible to delete/invalidate all collection region, a specific collection region or flushes the cache provider.

The execution type differ on how you execute the command.
If you want to invalidate all entries for an collection region this command would do the work:

<info>%command.name% 'Entities\MyEntity' 'collectionName'</info>

To invalidate a specific entry you should use :

<info>%command.name% 'Entities\MyEntity' 'collectionName' 1</info>

If you want to invalidate all entries for the all collection regions:

<info>%command.name% --all</info>

Alternatively, if you want to flush the configured cache provider for an collection region use this command:

<info>%command.name% 'Entities\MyEntity' 'collectionName' --flush</info>

Finally, be aware that if <info>--flush</info> option is passed,
not all cache providers are able to flush entries, because of a limitation of its execution nature.
