Hello, we are experimenting with Couchbase and ElasticSearch.
I know this may sound strange but when we run them both (on the same machine) we get much slower response times from Couchbase set operations.
If we take down the ElasticSearch process (leaving the XDCR replication as it is configured), we get back the higher performance.
Our set operations do not wait for persistence or replication. They are simple set operations that should go to RAM.
For example, when ES is not running, we are able to insert 8000 docs per sec. in Couchbase.
When we run ES, the same 8000 docs take about 5 sec. to insert to Couchbase.
Is this normal? If so, why does it happen?
Even when we have ES running, the machine has enough RAM, and the Couchbase bucket also have enough RAM allocated.
We are using Couchbase 2.2 and ES 0.90.5
Any help would be appreciated.
