Check Cluster Name Validation for Distributed Table Creation

Why it matters

This feature addresses the issue where Distributed tables could be created with invalid cluster names, which could cause misconfigurations and runtime errors. By enforcing cluster name validation, it ensures data consistency and reliable table distribution across the cluster.

How to use it

When creating a Distributed table, specify a valid cluster name. The system will automatically validate the cluster name and reject the creation if the cluster name is incorrect, requiring correction before the table can be created.
