Example 13 with CalciteCatalogReader

use of org.apache.calcite.prepare.CalciteCatalogReader in project druid by druid-io.

the class DruidPlanner method getValidator.

    // but it is private and has no accessors, so make another one so we can get the parameter types... but i suppose
    // beats creating our own Prepare and Planner implementations
