Is there a good formula to calculate heap utilization in Cassandra pre-1.1,
specifically 1.0.10. We are seeing gc pressure on our nodes. And I am
trying to estimate what could be causing this? Using node tool info my
steady state heap is at about 10GB. XMX is 12G.
I have 4.5 GB of bloom filters wh
I guess to answer that, you would need to first ask if it would be worth
redoing the 4+ years of development that has gone into Cassandra. There have
been many discussions about porting it to C/C++ and always is the same
response; it's just not worth the rewrite for the incremental gain. Also, s
I got introduced to Scala recently and found its features on Futures and
Function composition very neat.
Cassandra utilizes Futures and essentially passing around functions (using
anonymous inner subclasses) a lot, if expressed in Scala , it could be much
simpler and smoother. just a random though

Hi All :)
I have an application which use DataStax Java driver v2.0.2 to connect
to Cassandra Cluster (6 nodes, v 2.0.11).
Application is deployed in three copies on 3 different servers. From
time to time on random application server I get this exception:
