New zone routing to allow clients to write to local zones while server nodes route to zones #342

Open GoogleCodeExporter opened 8 years ago

GoogleCodeExporter commented 8 years ago 
Currently, when using zone routing, clients will write the number of 
preferred/required times to all zones.  This can be very costly on bandwidth 
when zones are actual geographical zones (data center to data center).

A solution to this would be to add more logic to the server side and give the 
client the option to only write to its local zone.  The first server written to 
in the local zone can be responsible for updating one node in each of the other 
zones.  The one server that gets the write in each of the other zones can be 
responsible for updating its peers within that zone.  This way a client can 
satisfy its write preference/requirement only within its local zone and one 
single write can propagated per zone.
