Hello, What options for cross-cluster communication does StarRocks currently support? In other words, if I have two separate shared-data clusters, am I limited to EXTERNAL TABLEs only or are there better ways to tie them together for data, jobs and compute exchange?

For now, external table is the only way of workaround. But would you like to tell me more about the background of this requirement? why did you create two separate shared data clusters? If multi-warehouse is available, will you create one cluster? Multi Warehouse will be available in v4.1, i’m wondering if this will resolve your issue.

@Alvin Zhao - the idea is as follows - I have multiple distinct datacenters each running its own kubernetes environment. Clusters run in shared-data mode backed by s3 storage and cross-datacenter access to s3 storage is possible. I am looking for ways to establish communication between starrocks instances deployed in these datacenters. Depending on how exactly multi-warehousing is implemented - it might be suitable for my usage pattern
