------------------------------------------
Summary: 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
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).
