Rui Li commented on FLINK-21045:
--------------------------------
Thanks for looping me in. I don't have a strong opinion regarding
{{CREATE/DROP}} vs {{LOAD/UNLOAD}} either.
But I do believe introducing {{USE MODULES}} is very useful (and perhaps we
should add similar function to the API). My reasons are 1) it's very tedious to
unload old modules just to reorder them 2) users may not even know how to
"re-load" an old module if it was not initially loaded by the user, e.g. don't
know which type to use.
> Support 'load module' and 'unload module' SQL syntax

> At present, Flink SQL doesn't support the 'load module' and 'unload module'
> SQL syntax. It's necessary for uses in the situation that users load and
> unload user-defined module through table api or sql client.
> SQL syntax has been proposed in FLIP-68:
