Current recommendation is to do count query on visibility. We will have to think about a long term solution.

Worker does not have a gRPC service endpoint. It would be good to have sdk to implement the health check so whoever running a worker would have it.

It is not officially claimed as supported, but there is no issue using OpenSearch as visibility store.

Server is not crack open those failure and just pass it along. It would be hard for server to arbitrary determine what is the cutoff depth.

Can you try to remove all filters? Or try using temporal/CLI to see if you can list workflow from using the CLI.

Seems like web ui issue.
