Rails 7.1 ships with connection-pooling enabled by default for
`RedisCacheStore` (see rails/rails#45235).
Because we already wrap our Redis clients in our own `ConnectionPool`
($alfred / $velma), the upgrade resulted in a double-wrapped object and
runtime errors such as:
NoMethodError: undefined method `get` for an instance of ConnectionPool
This patch:
* Passes `pool: false` when instantiating `RedisCacheStore` in
`config/initializers/rack_attack.rb`, telling Rails to use the pool we
supply instead of building its own.
* Adds an inline comment explaining the rationale.
* Adds a TODO in `config/initializers/01_redis.rb` suggesting a future
simplification: switch to plain Redis clients and let Rails manage the
pool.

MemCacheStore and RedisCacheStore” -

false`) [Ruby on Rails
