Is your feature request related to a problem? Please describe
The validateClusterNodeMembership setting is enabled by default for clustered connections. When adding new nodes to the topology, especially in cases like node upgrade, this setting causes problems as typically the topology update happens later than the first MOVED / ASK responses are received, causing
UnknownPartitionException: Connection to <node> not allowed. This partition is not known in the cluster view.
Describe the solution you'd like
Similar to #3249 this setting is disabled in the recommended connection options of most cloud providers and the Redis documentation.
It was introduced years ago, so it is also a breaking change to swap the default, so we should be targeting major release.
We should change the default of the validateClusterNodeMembership to false and update the documentation
Describe alternatives you've considered
Same as with #3249 educating the user was an approach that did not seem to help much.
Teachability, Documentation, Adoption, Migration Strategy
Users that depend on the node validation should manually enable it using the ClusterClientOptions
