> Issue description: Once the admission control is configured (with the
> MAX_MEM_ESTIMATE_FOR_ADMISSION, MEM_LIMIT, etc,etc query options), if a user
> bypass the default setting setting the query options in the session it can
> cause queries failures in the pools configured (e.g decreasing
> MAX_MEM_ESTIMATE_FOR_ADMISSION and increasing MEM_LIMIT).
> Improvement: It will be great to have a further checkboxes (with those
> default values) like "do not allow user to override this value".
> The value can be changed eventually by the query optimizer, but we do not
> allow users to change MAX_MEM_ESTIMATE_FOR_ADMISSION at all.
