View Source AntikytheraCore.ExecutorPool.AsyncJobRunner (antikythera v0.5.1)

An ephemeral GenServer process under PoolSup that manages an execution of an async job.

Actual execution of gear's code is done within a separate process for the following reasons:

  • for cleaner error handling
  • to introduce timeout of job execution
  • to be responsive to system messages

When the separate process terminates, this GenServer updates/deletes the locked job in the queue depending on the result of the execution.

Note that when no job is registered in the job queue, successfully checked-out process is immediately checked in. See implementation of AntikytheraCore.ExecutorPool.AsyncJobBroker.
