Online upgrade from 1.8.1 to 2.0.1-160
- Each server has 8GB RAM and 100GB disk
- Create 4 nodes 1.8.1 cluster with 2 buckets, default (4GB) and sasl (2GB).
- Load 10M items to default bucket and 2 M items to sasl bucket.
- Let the load running in 2 hours with delete, set, get and expire items.
- Create a 2.0.1-160 node.
- Do online upgrade to cluster from 1.8.1 to 2.0.1 by add 2.0.1 node to cluster and remove one 1.8.1 out of cluster. No load running.
- erl.exe got about 300MB. When I start the load around 1K ops to cluster, 2.0.1 node became unstable and erl.exe memory used went up to 1.3 GB.
- Stop the load, memory used by erl.exe did not go down.
