CouchDB and Elasticsearch on same machine
Hi,
for a first small "testing" deployment of our application I would like to run CouchDB and elasticsearch on the same machine to save some costs. After demand grows i plan to separate them.
Does anybody have experience with this, any specific issues to take care of?
I remember that several times i faced a problem with heavy CPU + memory usage of couchdb. Is there any way to limit this, so it will nicely co-exists with Elasticsearch? I read that elasticsearch makes trouble when the system starts swaping ...
Really appreciate any thoughts and comments.
Thanks in advance!
Thomas

Thomas,
we don't limit the memory for couchdb, but elastic is set to 1GB. Our box
is a dual core vm, with 2GB on it.

Hi Luke,
thanks, that's a great idea. I will follow this advice.
How about memory and CPU? Did you had to limit couchdb? For elasticsearch's JVM i know you can set 'max-mem' ...

We run this set up in QA with no real trouble, although we don't have very
high traffic on that box. I would suggest you give the box a couple of
cnames, like test-couchdb and test-elasticsearch; then when you create the
indices on test-elasticsearch you point them to test-couchdb; this should
help separation in the future.
