Install couchbase server1.8.1-810 on2 centos 5.4 nodes. Each node has 48 GB RAM and 200 GB storage
Create 2 nodes cluster and default bucket.
Using mcsoda script:
- Load 30 million items with size 256 bytes to default bucket. Stop the load when 30 million items loaded.
- Load 7.5 million items using 3 threads with total ops around 20K ops. Keep the load running after load 7.5 million items. The script does create, update and get items.
The mb-wal file keeps increasing up to 1 GB
