Fields

calls: Vec<WindowFunction>

partition_by: Vec<u32>

order_by: Vec<ColumnOrder>

use repeated in case of future extension, now only one column is allowed

state_table: Option<Table>

intermediate_state_table: Option<Table>

Optional state table for persisting window function intermediate states. Used for numbering functions (row_number/rank/dense_rank), and with watermark_trigger_table.

watermark_trigger_table: Option<Table>

Indexes partitions by the watermark of the order key that may close their windows. Present iff some call may be closed by watermark, in which case intermediate_state_table has a trailing progress column storing window_function.EowcPartitionProgress.
