Subject Re: cassandra for a inbox search with high reading qps
Date Tue, 31 Aug 2010 00:18:59 GMT
what's the average size of a user?

As I know, lucandra will first poll the data from cassandra, then do
computation in the client. That's ok for small rows.
But we have 1M row in average, and some rows scale to 100M; at the same
time, we expect high reading qps.
Polling these data to client machine through network is unacceptable.

I have setup a demo system which do the searching locally in cassandra; it
seems working with reading qps 1000+ per node.
