Compatibility Matrix for the ODBC/JDBC clients

Hello,

Does Drill mandate the perfect alignment of the Drillbits versions and the
ODBC/JDBC client versions, or is it possible to use an older client with a
new server or vice versa?

Regards, Joel

Hey Joel…

My experience has been the JDBC-side was more tolerant than the free ODBC driver. It took a bit for the ODBC driver to be released after Drill 1.13.0 and the macOS and Linux ODBC versions (I don't use legacy Windows operating systems) kept tossing messages in logs to the point where I rly didn't want to trust them so just used JDBC until parity was reached (IIRC it was protocol-buffer related which makes sense since those binary bits have to be meticulously maintained).

I've definitely mixed-and-matched JDBC & Drill version (unintentionally) without detriment, but would (again IMO) strongly suggest keeping versions aligned.
