* `CASSANDRA_CFG_ENV_`: Will add the corresponding key and the provided value to `cassandra-env.sh`.
* `CASSANDRA_CFG_RACKDC_`: Will add the corresponding key and the provided value to `cassandra-rackdc.properties`.
* `CASSANDRA_CFG_COMMITLOG_`: Will add the corresponding key and the provided value to `commitlog_archiving.properties`.
* `CASSANDRA_CFG_YAML_`: Will add the corresponding key and the provided value to `cassandra.yaml`.
For example, use `CASSANDRA_CFG_RACKDC_PREFER_LOCAL=true` in order to configure `prefer_local` in `cassandra-rackdc.properties`.
To update the `cassandra.yaml` file and set `internode_compression` to `all` use `CASSANDRA_CFG_YAML_INTERNODE_COMPRESSION=all`.
In the same way you can update nested options in the `cassandra.yaml`. For example, `CASSANDRA_CFG_YAML_CACHED_ROWS_WARN_THRESHOLD` will set `cached_rows_warn_threshold` in the `replica_filtering_protection` section.
**NOTE:** Environment variables will be omitted when mounting a configuration file
