 ### Running
 #### Preparing Couchbase Clusters
 Before running the differ to examine consistencies between two clusters, it is *highly recommended* to first set the Metadata Purge Interval to a low value, and then once that period has elapsed, run compaction on both clusters to ensure that tombstones are removed. Compaction will also ensure that the differ will only receive the minimum amount of data necessary, which will help minimize the storage requirement for the diff tool.
