Hi community, As you know, ShardingSphere has made a lot of efforts on SQL parser and provided a great independent SQL parser to help users parse SQL.
Based on this substantial work, we plan to do query optimization to optimize the input SQLs from users and produce an optimized SQL query plan to improve query efficiency. Plus, the federated SQL query feature (Like join query from different instances) is another essential highlight for our next release. : ) We will leverage Apache Calcite, an excellent framework to implement two of the features. Actually, there are plenty of works to do on this issue. We are in the investigation phase now and will seek contributors for this issue later. If you are interested in this one, please give [1] a watch.
