-------------------------------
Summary: Limit the number of concurrently running jobs
Key: CRUNCH-307
URL: https://issues.apache.org/jira/browse/CRUNCH-307
Project: Crunch
Issue Type: New Feature
Components: Core
Reporter: Chao Shi
Assignee: Chao Shi
Attachments: crunch-307.patch
In current behavior, crunch keep submitting new jobs as long as their
dependencies have finished. This is not good on a scenario where a pipeline
consists a large number (e.g. 10+) of independent DAGs. A improvement is to
define a limited window of concurrent running jobs. Whenever such limit is
reached, we stop submitting new jobs and wait until any running job finishes.
