Erick Tryzelaar commented on CASSANDRA-994:
-------------------------------------------
Regarding "replace isOnSameRack and isInSameDataCenter with getRack and
getDatacenter (replacing getLocation)", any idea what I can do with the
RackInferringSnitch? Just return the 2nd and 3rd octet as the rack and
datacenter?

> I think the EPS implementations should look like this:
> IEndPointSnitch: rename to IEndpointSnitch (lowercase P), otherwise fine as
> it is
> SimpleSnitch: new default snitch. Implement IEPS directly, with sorting as
> no-ops.
> AbstractEndpointSnitch: rename to AbstractRackAwareSnitch; replace
> isOnSameRack and isInSameDataCenter with getRack and getDatacenter (replacing
> getLocation).
> EndPointSnitch: rename to RackInferringSnitch
> PropertyFileEndpointSnitch: rename to PropertyFileSnitch, move from contrib
> to src
> DatacenterEndpointSnitch: remove (redundant wrt PFS). "quorum factor per DC"
> needs to go in the ReplicationStrategy, not the snitch.
> The patch sequence looks like:
> 01: perform renames of IEPS, AES, EPS, and PFES
> 02: add SS and make method changes to ARAS [was AES]
> Separate ticket: DatacenterReplicationStrategy code changes
