Where can I find a description of the expressions that can be used with
the Table operations, such as select() and filter()?
I've seen the examples use code like
> .select("word.count as count, word").filter("count = 2");
and
> .select("month as m, cnt.max as max")
The Table docs
(https://ci.apache.org/projects/flink/flink-docs-master/libs/table.html)
refer to the Javadocs, but they just say "field expressions can contain
complex expressions and aggregations", which doesn't really help...
And: can I reference POJO fields with these expressions?
Best,
