Zoltán Borók-Nagy commented on IMPALA-13140:
--------------------------------------------
Adding this flag could be problematic because:
* it degrades performance
* some code paths where we calculate buffer sizes expect strings to be
smallified, therefore these code paths should be updated too
** to verify everything works well we'd need to run the tests with and without
small string optimization
> Add backend flag to disable small string optimization
