States of Pilots and Jobs

Pilots

States:

  • active
  • dispatched
  • running
  • finished (completion of a job)
  • stopped (timeout w/o getting a job)

Jobs

States:

  • defined
  • dispatched (sent to a pilot)
  • running
  • finished

DAG

  • Vertex and Edge tables: vertices are jobs and the edges are data
  • Leaves of a DAG: can only be a job, not data (since all data are edges and not vertices). This also

has the benefit of not having final data unaccounted for - it must me either flushed or moved to permanent storage in most cases. The job/task responsible for it forms the leaf.
