Description
Steps To Recreate:
Crash Recovery Test
- Created a 4 node cluster(replicas =1, bucket_ram_quota = 256MB per node)
- Loaded 40 million Items (item size = 256 bytes, DGM =5%)
- Start doc ops (create:expiry).
- During doc ops, keep doing graceful restarts (we do wait for bucket warmup before triggering next graceful restart. after bucket warm up there is a sleep of 30 to 60 secs before triggering next graceful restart)
