Stefan Fleiter commented on CASSANDRA-4482:
-------------------------------------------
This solutions seems conceptionally simpler and more robust to me than hinted
handoff.
* No additional write load is added
* No necessary knowledge of other nodes state
* Repair can be controlled by each node themselves
* If a repair gets interrupted it can be restarted easily
* Existing Hinted Handoff problems are large in count
** A search for open Cassandra Hinted Handoff bugs results in a list of over
500 issues
So a usage scenario for "In-memory merkle trees for repair" might be to let
this replace HH entirely.
