[SizingIssue - c5.2xlarge, gsi-n1ql colocated]: Unbounded queries are failing either due to index scan timeout or due to temp file size exceeded limit.




      1. Create a 5 nodes(c5.2xlarge) cluster: 3-KV, 2-GSI & N1QL colocated.
      2. Create bucket, 10 collections, 100M items in each.
      3. Create GSI indexes on 2 collections.
      4. Start KV Read+expiry load at 10k ops/s(5k Reads, 5k Expiry). Start the n1ql query load in parallel.
      5. Scale up cluster to 4-KV, 3-GSI & N1QL. Finished in 16122.9400001 seconds
      6. Scale up cluster to 5-KV, 4-GSI & N1QL. Finished in 13892.306 seconds
      7. Scale down cluster to 4-KV, 3-GSI & N1QL. Rebalance still running since 7 hours.
      8. During the rebalancing + incremental index building + plasma compaction(keys getting expired in 10s) + Query workload - N1QL queries(QueryScanConsistency.NOT_BOUNDED) are timing out due to index scan couldn't complete in 75s.
