Re: Reaper as cassandra-admin

As an aside, it’s frustrating that ya’ll would sit on this for months (first e-mail was April); you folks have enough people that know the process to know that communicating early and often helps avoid duplicating (expensive) work. 

The best tech needs to go in and we need to leave ourselves with the ability to meet the goals of the original proposal (and then some). The reaper UI is nice, I wish you’d have talked to the other group of folks to combine efforts in April, we’d be much further ahead.
