2c: There's a lot to think about here, and as Blake already mentioned most people don't have time to dedicate a lot of thought to this at the moment. There appear to be a lot of voices missing from the discussion, and I think it's pretty clear this isn't super tied to the freeze, so maybe we

IMO, I am glad to see there are at least three solutions here to address repair and can be potential candidates for sidecar. As Joey pointed out, all of them may not be great at everything they do, and to me, it makes sense to "cherry pick" the best each product has, and build a good C* sidecar.

I share Dinesh's concern too regarding tech debt with existing codebase. Its good we have multiple solutions for repairs which have been always painful in Cassandra. It would be great to see the community take the best pieces from the available solutions and roll it into the fresh side car which

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

Hey folks, Mick brought this up in the sidecar thread, but I wanted to have a clear / separate discussion about what we're thinking with regard to contributing Reaper to the C* project. In my mind, starting with Reaper is a great way of having an admin right now, that we know works well at the
