 It works well for CSVs that can easily be fully loaded into memory (easily up to a hundred MB). Currently, there isn't a "large" file mode with proper readers and writers for ingesting CSVs in bulk with a fixed amount of memory. It correctly handles both `\n` (LF) and `\r\n` (CRLF) line endings (ie it should work with Windows and Mac/Linux line endings) and has UTF-8 support.
