@Deprecated public class TableAccessMap extends Object
Deprecated.
As of 1.30.0, if you need to know how tables in a plan are accessed you are encouraged to implement your own logic (using a RelNode visitor or other). The class is not used anywhere in the project and remains untested thus it is deprecated.
TableAccessMap represents the tables accessed by a query plan, with READ/WRITE information.
