> Memory assigned out of the budget in hash join for large objects

> Key: ASTERIXDB-2571
> URL: https://issues.apache.org/jira/browse/ASTERIXDB-2571
> Project: Apache AsterixDB
> Issue Type: Bug
> Components: *DB - AsterixDB
> Affects Versions: 0.9.4.1
> Reporter: Shiva Jahangiri
> Assignee: Till
> Priority: Major
>
> Currently in optimized hybrid hash join in case of lack of memory asterix
> flushes the big prob object to the disk. For flushing a big object, a
> variable sized frame will be created from hyracks context not join memory
> budget. This means we may use more than the given budget.
> Possible solutions:
> 1) Have a way to flush the incoming frame/buffer directly to the disk.
> 2) Spill enough data to be able to fit the large object(less preferred as it
> hurts the performance).
