**[Artem Bilan](https://jira.spring.io/secure/ViewProfile.jspa?name=abilan)** commented +1 for `RedisKeyValueMetadataStore` and maybe with the configurable `prefix` to distinguish pairs for this instance from others on Redis server.

**[Artem Bilan](https://jira.spring.io/secure/ViewProfile.jspa?name=abilan)** commented See the Reference URL for the problem in Redis cluster. So, that might make sense to revise this issue and implement it finally.
