Docker composite for cassandra stress testing

2GB RAM x 2 CPU cores

Composite uses official cassandra image

Change MAX_HEAP_SIZE

#look at etc/cassandra/cassandra-env.sh
cat etc/cassandra/cassandra-env.sh | grep MAX_HEAP_SIZE

Run containter

#start composite
docker-compose up -d

#start containter statistics
docker stats

Run stress test

#run container bash
docker exec -ti <cassandra-container> /bin/bash

#run write test
cassandra-container$ cassandra-stress write n=1000000

#run read test
cassandra-container$ cassandra-stress read n=1000000
