@junwen12221 That's great! Your link above shows me you spent many efforts on your community, I am not unsure whether you would like to put your mind and experience to best use, I mean, this wonderful feature. :-) Currently, we have another veteran, @guimingyue . BTW, recently one issue confused me a lot. Could I listen to your great idea? The basic process is, > SQL Statement (parsed ShardingSphere parser)-> RelNode(tranlasted from SQL Statment, need developing)->Optimized RelNode (optimized by CBO) **My question is** how to tell Calcite adaptor to use these optimized RelNodes? AFAIK, Driver.getConnection(CALCITE_URL) is the only way to trigger Calcite to use the custom adaptor, which will bring another SQL parsing from Calcite instead of using our optimized RelNode, doesn't it? How can we use the custom adaptor without calcite parser? Your GitHub activity tells me you are skillful at Calcite, anticipate your ideas. : ) Indeed, we welcome any comments from guys in the community! ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
