Hi folks,
Excuse me for this help-seeking email. I tried to query the related questions
on Stack Overflow and Apache Pony archived emails, but there is no answer there.
From my understanding, Flink parses SQL with the help of JavaCC and Apache
calcite. Therefore, why does Flink import Antlr at the same time? For what?
Could anyone give me some hints? Thanks in advance.
Best wishes,
Trista
