public class AlignedWindowTableFunctionOperator extends WindowTableFunctionOperatorBase
The operator for aligned window table function.

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

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

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