How to configure BigGraphite

Settings are either set in Graphite/Carbon configuration (when embedded), via command line flags, or via environment variables.

Generic

STORAGE_DIR: Storage directory to use, currently mostly use to store the cache
BG_DRIVER: One of cassandra (for production) or memory (for debug)

Cassandra Backend

This is the main backend for BigGraphite and the one that should be used in production.

BG_CASSANDRA_KEYSPACE: keyspace to use (default: biggraphite)
BG_CASSANDRA_CONTACT_POINTS: Cassandra contact points (default: 127.0.0.1)
BG_CASSANDRA_PORT: port to use to contact Cassandra (default: 9042)
BG_CASSANDRA_CONNECTIONS: number of Cassandra workers to use (default: 4)
BG_CASSANDRA_TIMEOUT: default timeout for operations (default: None)

Memory Backend

The in-memory backend can be used during development to make debuging easier.
