[DISCUSS] Improvements to the Unified SQL Connector API
as some of you might have noticed, in the last two releases we aimed to
unify SQL connectors and make them more modular. The first connectors
and formats have been implemented and are usable via the SQL Client and
However, after writing more connectors/example programs and talking to
users, there are still a couple of improvements that should be applied
to unified SQL connector API.
I wrote a design document  that discusses limitations that I have
observed and consideres feedback that I have collected over the last
months. I don't know whether we will implement all of these
improvements, but it would be great to get feedback for a satisfactory
API and for future priorization.
The general goal should be to connect to external systems as convenient
and type-safe as possible. Any feedback is highly appreciated.
