Hi, is it possible to operate Spryker with Redis in cluster mode? Did anybody tackle this topic alre

we have recently switched from single-instance Redis to Redis Sentinel. it was pretty straight forward and works quite well

Yes, but Redis Sentinel and Redis Cluster are two different things.

true. I was just not sure, if you maybe meant the same thing (some people don't differentiate) and wanted to mention that Sentinel works.

Here is a part of internal article:
Redis Cluster Redis Cluster is much more advanced tool for distributed Redis setup: performance, scalability, sharding, etc Official documentation: <https://redis.io/topics/cluster-spec> This solution comes with limitations, particularly around multi-key operations. So in case of Spryker it doesn't work out-of-the box, since Spryker is using MGET and KEYS * operations, which are not supported in cluster mode (even with single shard - <https://stackoverflow.com/questions/51248853/how-can-a-single-shard-redis-cluster-give-crossslot-errors>) In future we may support it with following changes: Not using multi-key operations Writing keys with hashes end ensure, that they are written in the same slot: <https://aws.amazon.com/premiumsupport/knowledge-center/elasticache-crossslot-keys-error-redis/>
