3. Create 100 fts indexes each with partitons=1 on 100 collections using rest api
2021-05-09 22:53:36,375 | test | INFO | MainThread | [Collections:create_fts_indexes:335] Creating 100 fts indexes
|
the last Rest api calls return at
2021-05-09 22:56:45,744 | test | INFO | MainThread | [Collections:test_volume_taf:643]
4. Do some crud operations on documents
5. Rebalance-in a fts node (172.23.107.107) (so almost 4 minutes from the last rest call to create fts index)
2021-05-09 22:57:04,427 | test | INFO | pool-2-thread-2 | [table_view:display:72] Rebalance Overview
|
This rebalance got hung at 42% for a long time .
Hardware and RAM quota
RAM quota for FTS: 22 GiB
Each node CPUs: 8
Each node RAM: ~24GiB
CPU, RAM usage, FTS indexes building progress (is at 100%) - all look healthy
So not sure of why the rebalance got hung
