I’m using Couchbase 6.5.1
in 1 cluster I have 8 node (3 data, 3 index, 2 query)
I have 1 bucket contains 1 bio data.
If I plan to patch my server and have 1 hour downtime for each data node, then the step is :
- Failover node ( graceful or hard? )
- stop my node server, do the patch, restart
- add back server with full recovery
Is that the right step?
Is there better approach if I have big data? ( rebalance will take more time based on mt experience)
