------------------------------------
Summary: Add a delayed message cancellation to the embedded smoke
test
Key: FLINK-24364
URL: https://issues.apache.org/jira/browse/FLINK-24364
Project: Flink
Issue Type: Improvement
Components: Stateful Functions
Reporter: Igal Shilman
StateFun supports sending delayed messages with a user defined cancellation
token, and in addition canceling delayed messaging by providing this token.
This feature is based on best-effort and it is non-deterministic, therefore it
is difficult to craft an e2e test to capture it (it is covered with a unit
test, where the exact conditions can be fixed)
I propose non the less, to add it to the smoke as a leaf command, meaning, a
command that doesn't result in state increment either). But nevertheless it
basically simulates a user that is "clicking around".
