You could try an open source project call cassandra-stress of zznate.
First you must to have git client and maven.
Please reference here: git installation, maven installation
Clone the src from git.
# git clone https://github.com/zznate/cassandra-stress.gitThen you would find a folder named "cassandra-stress", cd it and build the binary.
# cd ./cassandra-stress # mvn installand mvn would create a sub folder "target", cd it and run the stress script.
# cd ./target/appassembler/ # sh ./bin/stress -o insert -b 1000 -n 2000000 localhost:9160Wish this helps.
