Redis Repositories with Cluster and lettuce breaks application initialization [DATAREDIS-508]

[spring-projects-issues]

Mark Paluch opened DATAREDIS-508 and commented

Application startup fails when using @EnableRedisRepositories and Redis Cluster with the lettuce driver. Spring Boot enables by default Redis Repositories when Spring Data Redis is on the class path.

Redis Repositories with Cluster and lettuce can't be resolved to a working scenario right. lettuce driver 3.x does not support Redis Cluster with Pub/Sub, only lettuce 4.2 has support for Redis Cluster with Pub/Sub. A possible workaround could be DATAREDIS-505 to run with disabled listeners.

Keyspace events are not broadcasted to the whole cluster, just locally. See redis/redis#2541

Is it possible to backport it to the version 1.8?
