------------------------------------------------
Summary: Skip container stop/restart for processors that have same
work assignment across rebalances
Key: SAMZA-2638
URL: https://issues.apache.org/jira/browse/SAMZA-2638
Project: Samza
Issue Type: Improvement
Reporter: Bharath Kumarasubramanian
Assignee: Bharath Kumarasubramanian
*Problem*:
As part of rebalance, we always expire the current work assignment and proceed
to signal consensus and start the container with new work assignment. It is
inefficient for the processors to do the above when there is no changes in the
work assignment between the active job model & the proposed job model.
*Changes*:
Processors perform onJobModelExpired and onNewJobModel only if there are
changes to their work assignment across the active and proposed job model.
