Defined Type: cassandra::environment::variable

Defined in:
manifests/environment/variable.pp

Summary

Creating an environment variable for Cassandra.

Overview

Each instance of this type is adding a environment variable to the Cassandra process. This enables you to set e.g. MAX_HEAP_SIZE, HEAP_NEWSIZE, etc.

The config class contains a factory for this type which will create instances for each key of cassandra::environment.

Examples:

directly created

cassandra::environment::variable { 'MAX_HEAP_SIZE':
  value => '8G',
}

factory generated

cassandra::environment:
  MAX_HEAP_SIZE: 8G
  HEAP_NEWSIZE: 2G

Parameters:

  • id (String) (defaults to: $title) —

    name of the environment variable

  • value (String) —

    value to be assigned to the variable
