Package org.apache.flink.table.planner.plan.nodes.exec

Class ExecNodeConfig

java.lang.Object
org.apache.flink.table.planner.plan.nodes.exec.ExecNodeConfig
All Implemented Interfaces:
org.apache.flink.configuration.ReadableConfig
@Internal public final class ExecNodeConfig extends Object implements org.apache.flink.configuration.ReadableConfig
Configuration view which is used combine the PlannerBase#getTableConfig() with the ExecNodeBase.getPersistedConfig() configuration. The persisted configuration of the ExecNode which is deserialized from the JSON plan has precedence over the PlannerBase#getTableConfig().

This class is intended to contain additional context information for ExecNode translation such as shouldSetUid() or helper methods for accessing configuration such as getStateRetentionTime().
