Hi Julian,
Thanks for your response. If I understand correctly (looking at other
adapters), Calcite-Arrow adapter would provide SQL front end for in-memory
Arrow data objects/structures. So from that perspective, are you suggesting
building the Calcite-Arrow adapter?
In this case, what we are
Sorry I didn’t read your email thoroughly enough. I was talking about the
inverse (JDBC reading from Arrow) whereas you are talking about Arrow reading
from JDBC. Your proposal makes perfect sense.
JDBC is quite a chatty interface (a call for every column of every row, plus an
occasional call t
Thanks for your thoughts Julian. I think, adding support for Arrow objects for
Avatica Remote Driver (AvaticaToArrowConverter) can be certainly taken up as
another activity. And you are right, we will have to look at specific JDBC
driver to really optimize it individually.
I would be curious if
I really like Julian's idea of unwrapping Arrow objects out of the JDBC
ResultSet, but I wonder if the unwrap class has to be specific to the
driver and if an interface can be designed to be used by multiple drivers:
for drivers based on Arrow, it means you could totally skip the
serialization/dese
Yeah, I agree, it should be an interface defined as part of Arrow. Not
driver-specific.
