public class UnalignedWindowTableFunctionOperator
extends WindowTableFunctionOperatorBase
implements org.apache.flink.streaming.api.operators.Triggerable<org.apache.flink.table.data.RowData,TimeWindow>

The operator for unaligned window table function.

See more details about aligned window and unaligned window in WindowAggOperator.

Note: The operator only applies for Window TVF with set semantics (e.g SESSION) instead of row semantics (e.g TUMBLE/HOP/CUMULATE).

This operator emits result at the end of window instead of per record.

This operator will not compact changelog records.

This operator will keep the original order of input records when outputting.
