SAMPLE_SIZE = 10000

TYPE_MAPPING = {<class 'int'>: <class 'bson.int64.Int64'>}

get_constraints(cursor, table_name)

Retrieve any constraints or keys (unique, pk, fk, check, index) across one or more columns. Since MongoDB doesn’t really support foreign keys this will only ever return unique constraints and primary keys

get_indexes(cursor, table_name)

Effectively an alias for get_constraints

get_key_columns(cursor, table_name)

Key columns are not supported so this always returns []

get_relations(cursor, table_name)

Relations are not supported so this always returns []

get_table_description(cursor, table_name)

Get a colletction description by fetching a sample of SAMPLE_SIZE and analyzing it’s contents. Because MongoDB doesn’t have a fixed document specification this is only an approximation but depending on the SAMPLE_SIZE relative to the collection size it can be rather accurate.

get_table_list(cursor)

Return a list of MongDB collections (tables)
