Steven Hawkins commented on TEIID-4520:
---------------------------------------

> Why not set "org.teiid.pushdownDefaultNullOrder=true" by default? Isn't the default of engine's behavior one would expect?

No, it is only best effort and it can have performance impacts due to the overhead for rearranging the nulls - it is of course especially expensive to move high to low as you'll have to buffer everything.

It looks like we do need to update the DatabaseMetaData.nullsAreSortedLow to also return false, since that is not guaranteed.
