Subject Re: Calcite in research - The ReProVide Query-Sequence Optimization in a Hardware-Accelerated DBMS
Date Sun, 10 May 2020 19:07:07 GMT
Hello all,
    This happened because of the support provided by this group. I'm always
grateful to this community.
You could also find another paper and the video which demonstrates the
prototype we developed using Apache Calcite(accepted and published in

More papers are on the way...

Thanks and Regards
