A table that is rolled up from another table.

The rows of the rolled-up table are created by grouping the rows of the input table by the roll-up property.

Parameters:

roll_up_property – The property to roll up.
roll_up_columns – List of top-level columns that should be rolled up alongside the roll-up property.

Parameters:

url – The URL of the table.
created – The creation time of the table.
description – The description of the table.
row_cache_url – The URL of the row cache.
row_cache_populated – Whether the row cache is populated.
override_table_rows_schema – The schema to override the table rows schema.
init_parameters – The initial parameters of the table.
input_tables – A list of Table URLs that are considered direct predecessors in this table’s lineage. This parameter serves as an explicit mechanism for tracking table relationships beyond the automatic lineage tracing typically managed by subclasses.

static get_nested_value_with_rollup_columns(row_data: dict[str, Any], roll_up_property: str, rollup_columns: list[str]) → Any#: Returns the value of the roll-up property, with the roll-up columns added to the leaf node.
