@ExecNodeMetadata(name="stream-exec-group-window-aggregate", version=1, consumedOptions={"table.local-time-zone","table.exec.mini-batch.enabled","table.exec.mini-batch.size"}, producedTransformations="group-window-aggregate", minPlanVersion=v1_15, minStateVersion=v1_15) public class StreamExecGroupWindowAggregate extends StreamExecAggregateBase
ExecNode for either group window aggregate or group window table aggregate.
The differences between StreamExecWindowAggregate and StreamExecGroupWindowAggregate is that, this node is translated from window TVF syntax, but the
* other is from the legacy GROUP WINDOW FUNCTION syntax. In the long future, StreamExecGroupWindowAggregate will be dropped.
