Carlos,
Yes, I'm running multiple clients simultaneously. Each one of them tries to
create table if it doesn't exists in the cassandra.
Ali,
I've cleared the data directory. Next time, If it reoccurs, I'll follow the
steps listed and come here again.
Thanks for the informatio

Hello Marcus,
I altered the table to set timestamp_resolution to 'MICROSECONDS'. I
waited for sometime, but the sstable count did not come down. Do you
think I should specific command to reduce the count of sstables after
setting this?
Thanks and Regards

How do I do that? Is stream_throughput_outbound_megabits_per_sec the
attribute in cassandra.yaml.
I think we can set that on the fly using nodetool setstreamthrou
Is DSE shipping with 3.x ?

This is how you create it dynamically:
KsDef ksdef = new KsDef();
ksdef.name = "ProgKS";
ksdef.replication_factor = 1;
ksdef.strategy_class =
"org.apache.cassandra.locator.RackUnawareStrategy";
List cfdefs = new ArrayList();
CfDef cfdef1 = new CfDef();
cfdef1.name = "ProgCF1";
cfdef1.ke
