xDB Dataset Growth and Purging

Is there anything we can do about the tremendous growth of our Mongo database?

This question comes up pretty often lately when working with the new versions of Sitecore.

The bad news is that there is currently no purge mechanism in place. This applies to any Sitecore 7.5 or 8.0 Mongo dataset, whether you are using the cloud or an on-premise set up.

A purge tool could potentially make its way into a future Sitecore release, but it isn't something that the product team is actively working on.

Real world example:

We stood up a client's Mongo collection on December 18th with FXM configured on 4 external sites.
As of April 1st, we are at 6.8 gigabytes!

Plan for growth, and lots of it!
