Wail Alkowaileet commented on ASTERIXDB-1670:
---------------------------------------------
I couldn't reproduce this issue again for some reason.
I'll mark it as not a problem for now.
> Java heap exceeded - COUNT(for $x in dataset Tweets return $x)

> Project: Apache AsterixDB
> Issue Type: Bug
> Components: Optimizer
> Reporter: Wail Alkowaileet

> Sounds like there is a new materialization bug.
> [~wyk] Can you please add the query plan for the query that failed with
> Exception.

> 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.
