Yes it is provisioned in Vapor, my vapor.yml has the cache: cachename entry and I see some activity on AWS monitoring (page caching at this point I guess)
I found redis is functional on my vapor instance BUT some commands that work locally don't work on vapor (Win vs Linux?).
ALSO, predis and phpredis do not behave the same, THEN using the Facades that handle the connection automatically hide the auto-complete I'd have using the classes directly... sigh.
A hint on debugging environment issues on Vapor: in AWS Lambda is a page where you can see all the injected environment variables. There I saw that Vapor indeed uses phpredis, I saw the url/port/password to the redis instance, etc.
@ITProperty Please understand it's 2 years later... No actual "solution" but we realized Vapor-AWS-redis used clusters that behave differently and don't necessarily support same instruction set. Pooling of commands was part of what we tried at the time, IIRC.
