Class DynamicSchema

java.lang.Object

org.apache.calcite.jdbc.CalciteAbstractSchema

org.apache.calcite.jdbc.SimpleCalciteSchema

org.apache.drill.exec.planner.sql.DynamicSchema

All Implemented Interfaces:

org.apache.calcite.jdbc.CalciteSchema

Direct Known Subclasses:

DynamicRootSchema

public class DynamicSchema
extends org.apache.calcite.jdbc.SimpleCalciteSchema

Unlike SimpleCalciteSchema, DynamicSchema could have an empty or partial schemaMap, but it could maintain a map of name->SchemaFactory, and only register schema when the corresponsdent name is requested.
