Re: Pycassa vs YCSB results.

Hi, Could some one please let me know any hints, why the pycassa client(attached) is much slower than the YCSB? is it something to attribute to performance difference between python and Java? or the pycassa api has some performance limitations? I don't see any client statements affecting the pyca

Thanks Tyler ... so I created my keyspace to explicitly indicate the datacenter and replication, as follows: create keyspace KEYSPACE_NAME with placement_strategy = 'org.apache.cassandra.locator.NetworkTopologyStrategy' and strategy_options={DC28:2}; And yet I still get the exact same error
