A place to share cassandra app code

Setup a python virtual env with python cassandra installed

# If pip is not present in you system
sudo apt update
sudo apt install python3-pip

# Install and activate virtual env (Linux/MacOS)
python3 -m pip install virtualenv
python3 -m venv ./venv
source ./venv/bin/activate

# Install and activate virtual env (Windows)
python3 -m pip install virtualenv
python3 -m venv ./venv
.\venv\Scripts\Activate.ps1

# Install project python requirements
pip install -r requirements.txt

Launch cassandra container

# To start a new container
docker run --name node01 -p 9042:9042 -d cassandra

# If container already exists just start it
docker start node01

Copy data to container

docker cp tools/data.cql node01:/root/data.cql
docker exec -it node01 cqlsh
#In cqlsh:
USE investments;
SOURCE '/root/data.cql'

Start a Cassandra cluster with 2 nodes

# Recipe to create a cassandra cluster using docker
docker run --name node01 -p 9042:9042 -d cassandra
docker run --name node02 -d --link node01:cassandra cassandra

# Wait for containers to be fully initialized, verify node status
docker exec -it node01 nodetool status
