Couchbase Server

Hi

There is uneven CPU spikes in few of the data node in couchbase cluster

cluster conf

4 index / query node

8 data nodes

3 of the data nodes experincing high CPU load when total transaction goes above 3K
The Vbuckets are equally distributed across all data nodes

Thanks

@haf my first guess, and assuming that it’s the memcached process that’s seeing the high CPU usage, would be document key hotspotting
