----------------------------------------------------------
[~csq] BTW, there are also many other built-in functions not supported besides
first_value/last_value. See
https://nightlies.apache.org/flink/flink-docs-master/docs/dev/table/functions/systemfunctions/
for more details. There are two columns: *SQL Function* and *Table Function*,
if a function is not supported in Table API, the *Table Function* column is
documented as *N/A*. Are you interested in also supporting the others?
