Your help and experience of analyzing the flink code will be appreciated.

Answer 1

For how job scheduling works in Flink, I would start looking at https://ci.apache.org/projects/flink/flink-docs-release-1.2/internals/job_scheduling.html. Generally, the last part of the current Flink documentation contains some good information about the internals of Apache Flink.
