## What it is
CCM (Cassandra Cluster Manager) is a Python script and library for creating, launching, managing, and destroying small Apache Cassandra clusters on a local machine. It is primarily intended for testing Cassandra clusters during development.

## Use cases
- spin up a local 3-node cassandra cluster for testing
- create and destroy cassandra clusters on localhost
- test cassandra replication and node bootstrapping locally
- simulate multi-node cassandra cluster behavior on one machine
- manage cassandra nodes for integration testing
- bootstrap additional cassandra nodes locally

## When to choose
- you need to test Cassandra cluster behavior locally without real infrastructure
- you are developing or debugging Cassandra itself or drivers against multi-node setups
- you want a lightweight scriptable way to create/destroy test clusters

## When to avoid
- you need production or cloud-hosted Cassandra clusters
- you want containerized cluster orchestration (use Docker/Kubernetes instead)
- you need large-scale clusters beyond a local box

## Facets
