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!
