The <info>%command.name%</info> command is meant to clear a second-level cache query region for an associated Entity Manager.
It is possible to delete/invalidate all query region, a specific query region or flushes the cache provider.
The execution type differ on how you execute the command.
If you want to invalidate all entries for the default query region this command would do the work:
<info>%command.name%</info>
To invalidate entries for a specific query region you should use :
<info>%command.name% my_region_name</info>
If you want to invalidate all entries for the all query region:
<info>%command.name% --all</info>
Alternatively, if you want to flush the configured cache provider use this command:
<info>%command.name% my_region_name --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.
