Subject Re: Configuring CouchDB/BigCouch for high-memory servers
Date Fri, 20 Apr 2012 12:41:52 GMT
Yes, it's deliberate. BigCouch (and CouchDB) doesn't typically
allocate a lot of memory (though lots of replication jobs would change
that). Having lots of RAM is recommended for the OS's disk cache,

These will be dedicated database servers, so all they'll do is run, compute and serve our
CouchDB backend.

instead of on-disk data.
