-----------------------------------
Summary: Ability to activate and de-activate operators in the DAG
Key: APEXCORE-565
URL: https://issues.apache.org/jira/browse/APEXCORE-565
Project: Apache Apex Core
Issue Type: New Feature
Reporter: Vlad Rozov
Currently, there is no ability to mark operators/streams as inactive and
activate or de-activate them at run-time based on a condition or event. It
should be possible to statically populate DAG, but mark some operators as
inactive, so stram app master will not allocate physical nodes for inactive
operators and will not request containers from Yarn or any other resource
manager. This will allow to save resources and better support batch operations
in Apex.
