Hi Julian
I test a bit, Java/C/MySql/Spark/Hive/ support double/float mod, but pg
seems not to support this. There's no oracle in my hand, so the oracle is
not tested yet.
Regards!

Calcite aims to cover the SQL standard, but it is not limited to it.
So, given that the MOD operator in the standard does not cover DOUBLE,
the conversation should shift to which other DBs support it. Is there
a consensus as to the semantics? Are there related features that we
should do too?

Hello Aron,
sorry I forgot to cover the part regarding the modulo operation.
Calcite again follows the standard on that respect, and the SQL standard
says:
operates on two exact numeric arguments with scale 0
> (zero) and returns
> the modulus (remainder) of the first argument divided by the sec
That's a good idea!
I believe a presentation on recent improvements/significant
changes/refactorings would be very interesting and useful to everyone here.
E.g. changes to planner, refactorings of join algorithms, improvements to
execution layer. I bet many of those topics have interesting details
I think it is a great idea!
Best,
Ruben
