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.
