Hi Peer,
I changed cassandra-env.sh and following are the parameters I used,'
MAX_HEAP_SIZE=8G
HEAP_NEWSIZE=1600M
You should uncomment the HEAP_NEWSIZE setting as well. I would leave it
with the default setting 800M until you are certain it needs to be changed.

Hi Erick,
In cassandra-env.sh, system_memory_in_mb was set to 2GB, I changed it into
16GB, but I still get the same issue. Following are my complete system.log

Hello all,
I have read a lot about Cassandra and I read about key-value pairs,
partition keys, clustering keys, etc..
Is key mentioned in key-value pair and partition key refers to same or are
they different?

“The key” should just be a synonym for “primary key”, although sometimes
people are loosely speaking about “the partition” (which should be “the
partition key”) rather than the CQL “row”.

Hello all,
We are trying to develop a language corpus by using Cassandra as its
storage medium.
https://gist.github.com/cdwijayarathna/7550176443ad2229fae0 shows the types
of information we need to extract from corpus interface.
So we designed schema at
databases in the past I've had to use a similar
strategy to speed up lookups (less different query parameters in that case
and more queries that would normally require lots of joins).
Hope this helps explain tradeoffs and costs.

I used following query for this.

This returns number of key value pairs when CF is relatively small. But
when I insert more key-velue pairs, I am getting error saying, errors={},

believe the error message will be more helpful as of 2.1.3.
