This PR adds a new option called
thousands
to the CSV reader. It accepts a single character used to identify thousands separators in decimal, float, or double values.By default, thousands is set to
NULL
. If specified, it must be different from thedecimal_separator
option.When dealing with misplaced thousands separators, we follow the same approach as pandas: simply remove them from the string and ignore whether they were correct.
The option has also been added to the Python client.
