Subject Re: Needed information on multi-process-zookeeper setup

Hi Vinay,

The agents process is the one that does the crawling.
The tomcat serves the UI, API, and Authority Service web applications.

MCF requires its connectors to be bounded in memory consumption.  That
means that once you determine how much memory you need, the consumption
isn't going to depend on the size of documents being crawled etc.  Adding
more memory beyond that point, therefore, is not going to help you.  The
amount of memory you need does, however, scale with the number of worker
