Vijay updated CASSANDRA-2506:
-----------------------------
Attachment: 0001-changes-to-interfaces.patch
0002-changes-for-dc-readrepair.patch
0003-changes-for-cql.patch
The idea is to make read_repair_chance=x to be a global setting which will
allow us to specify the inter DC repair chance.
Users can add use read_repair_chance_options={DC:x, DC2:x} to tune the amount
of RR needed within a DC.
If we dont specify RRCO then global will take into effect. For a single DC
installation users can just rely on RRC
> Push read repair setting down to the DC-level

> Currently, read repair is a global setting. However, when you have two DCs
> and use one for analytics, it would be nice to turn it off only for that DC
> so the live DC serving the application can still benefit from it.
