keith-turner opened a new issue #1049: Leverage ability to disable deletes in Accumulo 2.0
URL: https://github.com/apache/fluo/issues/1049
 
 
   Accumulo's delete processing can cause Fluo to have O(N^2) read and commit processing when
a key/value has lots of versions.  To avoid this, Fluo uses reflection to remove the Accumulo
delete iterator.  Performance improvements made in Accumulo 2.0 by apache/accumulo#244 break
Fluo's reflection code.  The reflection code does not need to be fixed though, instead deletes
can be turned off in Accumulo 2.0 using the option added in apache/accumulo#598.
