Hi folks,
It is not common practice and prone to low performance that `ExtractorEngine` and `FillerEngine` are used to get final SQL parsed result based on AST generated by ANTLR at present. Upon investigation, we would like to replace them with ANTLR visitor. It is scheduled as a long-term task and a big change for our 5.x release, and currently i am trying to do some basic work for our new branch[1]. After the groundwork (Roughly estimated time is one week. ) is basically laid, we would like to welcome anyone who is interested in it to join us for this wonderful sharding parser. Please watch this thread for follow-up. What’s more, welcome your any comment and suggestion!
