Seen on the latest few builds
Observed on:
2.0.1-153 Linux
4 Core 30GB SSD machines
Description
- Setup a 7 node cluster,
- RAM (for each physical machine): ~32GB
- create 2 buckets: default (bucket quota: 12000MB per node) and saslbucket (bucket quota: 7000MB per node)
- run a load (with just creates), until the item count hits a mark
- create 2 views over each of the buckets
- Run load that pushes system into DGM, ~80% resident ratio for default, and ~60% resident ratio for saslbucket
- Run queries continuously against the views as the load continues.
(for e.g.:
curl -X GET 'http://10.1.3.235:8092/default/_design/d1/_view/v1?startkey=0&stale=ok&limit=1000') - Noticed the increased swap usage.
- Start a new mixed load on both the buckets (creates, updates, deletes, expires).
- Setup XDCR to another 5 node cluster.
- Continue querying, noticed considerable increase in swap usage.
This behavior is seen with a cluster with views as well (no XDCR involved).
