Bases:
tlc.core.objects.tables.in_memory_rows_table._InMemoryRowsTableA procedural table where rows in an input table are optionally included given
An include range factor min/max (where 0 mean start of table, and 1 means end)
An ‘include_probability’ which determines the ratio of rows in the range to include. The actual probabilities are generated by a pseudo-random generator which guarantees identical outputs for identical configurations
- 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.
