Hi, We have a great interest in the new Table API & SQL. In Alibaba, we have added a lot of features (groupBy, agg, window, join, UDF …) to Streaming Table API (base on Flink 1.0). Now, many jobs run on Table API in production environment. But we want to keep pace with the community, and we have noticed that Flink Community reworked the Table API and also supported SQL. That is really cool. However, the Streaming Table API is still so weak. So we want to contribute to accelerate the Streaming Table API and StreamSQL growth.
It seems that we have complete Task-5 and Task-6 mentioned in the Work Plan <https://docs.google.com/document/d/1TLayJNOTBle_-m1rQfgA6Ouj1oYsfqRjPcp1h2TVqdI/edit#>. So can we start Task-7 and Task-9 now? Is there any more specific plans? I think it’s better to create an umbrella JIRA like FLINK-3221 to make the develop plan clearer. If I want to contribute code for groupBy and agg function, what should I do? As I didn’t find related JIRAs, can I create JIRA and pull a request directly? Sorry for so many questions at a time. - Jark Wu (wuchong)
