    Description

      When the number of pipelines increases, the number of pipeline supervisors also increase linearly. Each supervisor is essentially doing duplicate work of hitting ns_server's pools/nodes endpoint. Too many of these supervisors doing the same thing will cause un-necessary load.

      This should be avoided, and the effort should be deduplicated.
