Hi all,
I’m working on a project and we have Java benchmark test for testing the
performance when using Cassandra database. Create operation on a single node
Cassandra cluster is about 15K operations per second. Problem we have is when I
set up cluster with 2 or more nodes (each of them are on
of the test servers?
Cheers

your test data is going to a single partition?
- have you tried manually running a few inserts to see if you get any errors?

Hi,
No we are not using async writes.

Can you share your benchmarking code?

Hi all,
I have a cluster of three nodes and would like to ask some questions about the
performance.
I wrote a small benchmarking tool in java that mirrors (read, write) operations
that we do in the real project.
Problem is that it is not scaling like it should. The program runs two tests:

Hi,
I would like to ask how to calculate token for composite partition key using
java api?
For partition key made of one column I use
cluster.getMetadata().newToken(newBuffer);
But what if my key looks like this PRIMARY KEY ((parentResourceId,timeRT),
childName)?
I read that “:” is a separator
