Using with redis cluster about rails_performance HOT 5 CLOSED

can this help https://aws.amazon.com/premiumsupport/knowledge-center/elasticache-crossslot-keys-error-redis/ ?

values = keys.collect { |k| RP.redis.get(k) } because it will make a X amount of requests to the redis and probably it's not well optimized

I'm not familiar with redis, just want it to work.

I haven't tested this. But reading the article posted by @igorkasyanchuk I think a very simple solution would be to change https://github.com/igorkasyanchuk/rails_performance/blob/master/lib/rails_performance.rb#L26

from

@@redis = Redis::Namespace.new("#{::Rails.env}-rails-performance", redis: Redis.new)

to

@@redis = Redis::Namespace.new("{#{::Rails.env}-rails-performance}", redis: Redis.new)

This should guarantee that all rails_performance redis keys are going to end up in the same slot. @strelok1111 could you test this?

Just test in production, changing config file make this gem work with redis cluster.
@haffla thank you for simple solution. I think this case need to add in documentation.

@haffla if you can prepare a PR with fix or documentation it would be great. I'm closing this issue for now
