Hi Renkai,
thanks for the interest in Flink and the Table API/SQL! I would
recommend to maybe have a look into previous Pull Requests for new SQL
features such as INTERSECT [1] to get an overview of layers and classes.
I also recommend the design document [2] that describes the all planned
features. It might be good if you look for an easy task to start with [3].

Hope that helps.

Hi all:
I’m interested in Table API and SQL.As far as I know, the SQL supports
is very limited currently. I want to help improving related features, such as
distinct aggregates for SQL on batch tables, and aggregations for SQL on stream
tables. I don’t have much experience in developing SQL related things, what
could I do for these?
