> Currently, I don't see many docs explaining what a {{PLAN_ROOT_SINK}} is,
> even though it shows up in explain plans and runtime profiles. After more of
> the changes in IMPALA-8656 are merged, understanding what {{PLAN_ROOT_SINK}}
> is will be more important, because it will start taking up a memory
> reservation and possibly spilling to disk.
> I don't see any docs on data sinks in general, so perhaps it would be useful
> to create a dedicated page for explaining data sinks and how they work. We
> can start by documenting the {{PLAN_ROOT_SINK}} as that may be the most
> commonly used one.
> We should document all the changes being made in IMPALA-8656 as well.
