For large data transfers — for example, Pandas or Polars DataFrames with millions of rows — performance and reliability are critical.

It’s worth noting that even with a new driver, integration complexity often comes from platform differences, TLS/SSL requirements, and corporate IT policies rather than the library itself. For teams looking to simplify workflows, a driver that abstracts these nuances while maintaining control over memory usage and transaction safety would be a strong improvement over rolling your own ODBC setup.
