Hello everyone, 
For ticket storage, does CAS support Valkey (an open source fork of Redis - Belongs to Linux Foundation)? If it does, is it possible for it to be mentioned in the documentation?
Thank You and have a nice day.

I just tested this on CAS 7.3 and it worked.

https://apereo.github.io/cas/development/ticketing/Redis-Ticket-Registry.html

For my serverless valkey instance, I added this to property files, not sure difference between redis.host and cluster.nodes[0].host:

cas.ticket.registry.redis.enabled=true
cas.ticket.registry.redis.host=mytestinstance.serverless.usw2.cache.amazonaws.com
cas.ticket.registry.redis.cluster.nodes[0].host=mytestinstance.serverless.usw2.cache.amazonaws.com
cas.ticket.registry.redis.cluster.nodes[0].port=6379
cas.ticket.registry.redis.cluster.nodes[0].type=MASTER
cas.ticket.registry.redis.use-ssl=true
cas.ticket.registry.redis.enable-redis-search=false

and included the following dependency:
implementation "org.apereo.cas:cas-server-support-redis-ticket-registry"

I have not deployed this yet.

well, tried to deploy this to a cluster (ECS) with multiple tasks, seems not to work unless I only have a single tasks.
