Description
- Create a 7 nodes(c5.2xlarge) cluster: 3-KV, 2-GSI, 2-N1QL colocated.
- Create bucket, 10 collections, 100M items in each.
- Create GSI indexes on 2 collections.
- Start KV Read+expiry load at 10k ops/s(9k Reads, 1k Expiry). Start the n1ql query load in parallel.
- Scale up cluster to 4-KV, 3-GSI & 3-N1QL. Finished in 9063.69799995 seconds
- Scale up cluster to 5-KV, 4-GSI & 4-N1QL. Finished in 7320.00900006 seconds
- Scale down cluster to 4-KV, 3-GSI & 3-N1QL. Took 9600 seconds.
- Scale down cluster to 3-KV, 2-GSI & 2-N1QL. Took 14400 seconds.
- Do a EBS volume up scaling. As it is done online it finishes in few seconds
- Do a EBS volume down scaling. This triggers a swap rebalance of all the nodes and when it comes to indexer, rebalance is failing in a loop:
Rebalance exited with reason {service_rebalance_failed,index,{worker_died,{'EXIT',<0.551.105>,{rebalance_failed,{service_error,<<"Duplicate Index Instance">>}}}}}.Rebalance Operation Id = 8250dd0807df3eecab283616d414a845
