com.twitter.ambrose.service.impl.InMemoryStatsService

In-memory implementation of both StatsReadService and StatsWriteService. Used when stats collection and stats serving are happening within the same VM. This class is intended to run in a VM that only handles a single workflow. Hence it ignores workflowId.

Upon job completion this class can optionally write all json data to disk. This is useful for debugging. The written files can also be replayed in the Ambrose UI without re-running the Job via the bin/demo script. To write all json data to disk, set the following values as system properties using -D:

   {@value #DUMP_WORKFLOW_FILE_PARAM} - file in which to write the workflow json.
  {@value #DUMP_EVENTS_FILE_PARAM} - file in which to write the events json.

   * when script is replayed at the end
