Details

    Description

      1. Create a 3 node all services co-located cluster. Create a bucket, 2 collections, and load 75M items in each collection
      2. Create GSI/FTS indexes, CBAS datasets/indexes. Let ingestion for all to complete.
      3. Start the query load for all the services.
      4. Scale up cluster from 3->6->9->12->15->18. At each scaling completion increment the query workload post the scaling completion.
      5. Scale up cluster from 18->15->12->9->6->3. Before each scaling operation decrement the query workload post the scaling completion.
      6. At the last scale down from 6 nodes to 3 nodes, the rebalance out of the last node is failing during analytics rebalancing.
