There is no separate project which collects Calcite adapters. You will find a few projects around with different adapters that haven't been accepted into Calcite for various reasons (the author doesn't desire to, it's unlikely to be broadly useful, etc.) In general, I'd say we're always interested in accepting well-tested code that is expected to be generally useful.
The contribution of an adapter that no one else is likely to use may not be accepted, partially because when any new code is added, we also add the burden of maintaining that code. That said, even in that case, there's nothing stopping contributors for maintaining adapters external to the Calcite code base :) -- Michael Mior mm...@apache.org Le jeu. 14 févr. 2019 à 04:57, Hanan Yehudai <hanan.yehu...@radcom.com> a écrit : > > Hi all, > we are developing a calcite based adapter, are there any pre-requirements to > contribute it as part of calcite ? > is there another Apache project for adapter ( like Baheer for Flink/ Spark > sinks )? > >
