# [DRILL-8118](https://issues.apache.org/jira/browse/DRILL-8118): Add Option
to Allow Disk Use on Mongo Queries
## Description
MongoDB has a strange feature whereby queries which use more than 100MB of
memory will by default fail. Mongo allows the user to specify whether they
want the query to spill to disk which allows larger queries but at a
performance cost.
This minor PR adds the ability for a user to specify whether they want this
option included in Mongo queries. This only affects aggregate queries in
Mongo.
## Documentation
This adds a new config option to the mongo config: `allowDiskUse` which,
when set to `true`, will pass that parameter down to MongoDB during aggregate
queries.
## Testing
Ran unit tests
