Removes all keys matching the given pattern.
Removes all keys matching the given pattern. This command has no direct support in Redis, it is combination of KEYS and DEL commands.
KEYS pattern command finds all keys matching the given patternDEL keys expires all of themThis is usable in scenarios when multiple keys contains same part of the key, such as
record identification, user identification, etc. For example, we may have keys such
as 'page/$id/header', 'page/$id/body', 'page/$id/footer' and we want to remove them
all when the page is changed. We use the benefit of the naming convention we use and
execute removeAllMatching( s"page/$id/*" ), which invalidates everything related to
the given page. The benefit is we do not need to maintain the list of all keys to invalidate,
we invalidate them all at once.
Warning: complexity is O(n) where n are all keys in the database
this must be valid KEYS pattern

Cache API inspired by basic Play play.api.cache.CacheApi. It implements all its operations and in addition it declares couple more useful operations handful with cache storage. Furthermore, due to its parametrization it allows to decide whether it produces blocking results or non-blocking promises.
