KV-Engine Sprint 2021 June
Description
Build : 7.0.0-5219 (RC2)
Test : -test tests/integration/cheshirecat/test_cheshirecat_kv_gsi_coll_xdcr_backup_sgw_fts_itemct_txns_eventing_cbas_scale3.yml -scope tests/integration/cheshirecat/scope_cheshirecat_with_backup.yml
Scale : 3
Iteration : 2nd
There is a step to add 2 KV nodes to the cluster in a rebalance operation. This rebalance took 12h 15m to complete, and just index rebalance took 12h 8m.
Test console :
[2021-05-26T09:31:33-07:00, sequoiatools/couchbase-cli:7.0:cd12df] server-add -c 172.23.97.74:8091 --server-add https://172.23.121.77 -u Administrator -p password --server-add-username Administrator --server-add-password password --services data

Indexer nodes in the cluster : 172.23.120.81, 172.23.123.33, 172.23.96.243, 172.23.97.105, 172.23.97.110, 172.23.97.148
The logs were collected just a few mins before the rebalance completed.
Not sure if this is a regression, because the same symptom (slow rebalance) has been showing up in various tests, but the underlying issue could be different.
