Subject Re: [DISCUSSION] High-volume counters in Cassandra
Date Fri, 24 Sep 2010 15:01:18 GMT
Hmmmm...  would there be any way that others in the project that are familiar with the design
could help the authors to redo some of the elements to remove the internal clock structure
and get it to work properly before 0.7.0 is finalized?  Not sure if that's feasible, but I
would just hate to see *unreconcilable* differences :).
