org.apache.calcite.plan.RelOptRule
org.apache.calcite.plan.RelRule<EnumerableToLogicalTableScan.EnumerableToLogicalTableScanConfig>
org.apache.flink.table.planner.plan.rules.logical.EnumerableToLogicalTableScan
@Enclosing public class EnumerableToLogicalTableScan extends org.apache.calcite.plan.RelRule<EnumerableToLogicalTableScan.EnumerableToLogicalTableScanConfig>
Rule that converts an EnumerableTableScan into a LogicalTableScan. We need this rule because Calcite creates an EnumerableTableScan when parsing a SQL query. We convert it into a LogicalTableScan so we can merge the optimization process with any plan that might be created by the Table API.
