public class DatasourceTable
extends DruidTable

Represents a SQL table that models a Druid datasource.

Once the catalog code is merged, this class will combine physical information from the segment cache with logical information from the catalog to produce the SQL-user's view of the table. The resulting merged view is used to plan queries and is the source of table information in the INFORMATION_SCHEMA.
