Graph states

An executed graph can occupy one of the following states.

• N/A
  Job execution request has been registered and persisted. This status lasts only for a short interval.

• ENQUEUED
  Job execution command has been received. Job waits in Job Queue for later execution.

• READY
  Job initialization process is almost done.

• RUNNING
  Job is running.

• WAITING
  Used only by the engine as a component status.

• FINISHED_OK
  The job finished without a failure.

• ERROR
  A failure occurred during data processing or during initialization process.

• ABORTED
  The job has been aborted or killed.

• TIMEOUT
  May occur when the job execution exceeds a specified limit, but the TIMEOUT status is never visible in the execution history. Time-outed job may be aborted, thus the status changes from RUNNING to ABORTED.

• UNKNOWN
  When the server detects inconsistency of the job status, it is set as UNKNOWN. For example, when the server starts-up and there are RUNNING jobs in the database, which is impossible since the server has not started yet.
