Re: [Kai-devel] another dynamo implementation

[Cliff M. <cl...@mo...>]

I'm currently planning on rolling out an early version for a low-latency 
read system in production at Powerset.  I want to decouple partitioning 
from partition placement in the membership server before I do that.  
After that I plan on getting synchronization w/ merkle trees up and running.

I noticed that Kai doesn't currently have a vector clock 
implementation.  I have a working implementation in the Dynomite source 
here: 
http://github.com/cliffmoon/dynomite/tree/master/elibs/vector_clock.erl  
and the tests are here: 
http://github.com/cliffmoon/dynomite/tree/master/etest/vector_clock_test.erl.  
Feel free to integrate that in with Kai if you think it will be useful.
