How to get all keys by tag from Redis in Symfony?

Question

symfony

Good afternoon.
Symfony project using Redis.
I need to get a list of cache keys by tag .
I use the Symfony/Cache component (RedisAdapter) for caching.
To implement tagging, I use TagAwareAdapter (I pass RedisAdapter to its constructor).
As a result, each cache key can be assigned tags and invalidate the cache by tag. But that's it, there are no more options with tags.
Has anyone solved such a problem? Maybe there is a ready-made library for working with tags in Redis using php?

Redis doesn't have a "tag" data type out of the box. Tagging is carried out at the application level, in your case it is the TagAwareAdapter library. The easiest and fastest way to find out how this library stores the tag-key bundle is to study the source code.
