-----------------------------------
Summary: Expose cost of task initialization
Key: FLINK-17012
URL: https://issues.apache.org/jira/browse/FLINK-17012
Project: Flink
Issue Type: Improvement
Components: Runtime / Metrics
Reporter: Wenlong Lyu
Currently a task switches to running before fully initialized, does not take
state initialization and operator initialization(#open ) in to account, which
may take long time to finish. As a result, there would be a weird phenomenon
that all tasks are running but throughput is 0.
I think it could be good if we can expose the initialization stage of tasks.
What to you think?
