Hi folks,
Groundwork for our new parser has already finished ahead of schedule, mainly
including adding visitor entrance classes for different databases and creating
new parsed integrated test architecture.
At present, we would like to invite anyone who is experienced or interested in
ANTLR and SQL parser to join this long-term task for our 5.x release!
Welcome step forward and give your comment if you want to be part of this
important task. :-)
Best wishes,
Trista

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!
