> Sounds like there is a new materialization bug.

> 1- returning the whole tuple
> count( for $x in dataset Tweets
> return $x
> )
> => Throws an exception Java heap exceeded. (The heap-size is less than the
> sum of AsterixDB configured memory ... so it's not a problem).
> {noformat}
> {noformat}
> 2- However, returning one field
> count( for $x in dataset Tweets
> return $x.id
> )
> => Worked just fine.
