   Closing https://issues.apache.org/jira/browse/ACCUMULO-1836 in favor of this ticket. Below is the description of the jira ticket in case it could be helpful:
   
   > Right now, if I have a key-value pair and I want to make an insert out of it, I have to do something like this:
   
   > m.put(key.getColumnFamily(), key.getColumnQualifier(), new ColumnVisibility(key.getColumnVisibility()), value);
   However, I believe this results in the data in the key being array copied twice which is pretty inefficient (profiling shows this to be a fairly significant portion of our running time on heavy ingest). Since I think exposing the byte arrays directly is not preferred, perhaps there could be a method Mutation.put(Key,Value) that efficiently re-uses the byte arrays. Maybe it assumes the rows are the same, or maybe it could have an option for checking that.
