Hi,
Very happy to hear you're willing to contribute community. Contribution to

Hi,
Regarding to the `open()/close()`, I think it's necessary for Table&SQL to
compile the generated code.
In Table&SQL, the watermark strategy and event-timestamp is defined using
SQL expressions, we will
translate and generate Java code for the expressions. If we have
`open()/close()`, we don't
There is a file 'WordCount.java' in the codebase.
You can start executing and debugging it to understand how the whole flow
works. And then you can start exploring further which would help you to
identify the issues you can work upon.

Hi,
I hope to contribute some simple code to flink, But it is
difficult for me to find a problem that is suitable
for myself among the many problems of JIRA.
I think many people will have the same problem, that is how to
get a simple question and then contribute
their first code. Thi
Thanks, Aljoscha, for picking this up.
I agree with the approach of doing the here proposed set of changes for
now. It already makes things simpler and adds idleness support everywhere.
Rich functions and state always add complexity, let's do this in a next
step, if we have a really compelling ca
+1 to return emty iterator and align the implementations.

Hi Tang Yun,
I agree with the point you mentioned that align these internal behavior
to return empty iterator instead of null. In my opinion,
StateMapViewWithKeysNullable handle nullable map keys, and result of
internal map state should be empty map in the null behavior case. Therefore,
as you
Hi devs
This thread is inspired by FLINK-17015 [1] which meet NEP when SQL guys develop
operator based on internal map state.
Unfortunately, we have different behavior of result of internal map state. For
HeapMapState, #entries(), #keys(), #values(), and #iterator() would all return
null. Howe
