Danny Chen commented on CALCITE-5251:
-------------------------------------
[~julianhyde] We have not documented specifically for RelNodes, whether a
\{{RelNode}} implements \{{Hintable}} is kind of an interval behavior and
should be transparent to users, WDYT ? It's more valuable to document about the
general Hints syntax which we already have on the website.
BTW, more and more \{{RelNode}}s implement \{{Hintable}}, we may need to
re-think the design about whether we should abstract out the \{{Hintable}} as
base clazz for all the \{{RelNode}}s for purpose of hints propagation or
something.
