Hi, We have defined a new SQL type RDL(Rule Definition Language) for ShardingSphere 5.x for rule configuration. There are still lots other new SQL types need to be defined (eg: SCTL). I plan to rename RDL module to DistSQL, and make RDL as subtype of DistSQL. And we can add more SQL type into DistSQL.
