Hi, fellows, I’m here again :) This time I want to have a full discussion about CALCITE-482, which is an issue fired at 27/Nov/14 by Vladimir Sitnikov.
Almost every sql vendor supports sql hint for their production version DB engines, so it would be nice if we have a framework in Calcite to support this, so that the engines that built based on CALCITE would have the ability to extend and have their custom sql hint implementations. In April this year I have fired an initial discussion about this topic[1], and I’m glad that we have some agreements for the design. Recently I have fired a PR[3] and write a design doc[2] mostly based on the discussion[1], so feel free to give some feedback here so we can make the hint framework more flexible. Any suggestions are appreciated.
