Review comment:
@luocooong, Thanks for the quick review. The deserialization should
only be affected if you remove config parameters. This defaults to `false`, so
if the user doesn't do anything, Drill's behavior stays the same.

> Add Option to Allow Disk Use on Mongo Queries
> ---------------------------------------------

> Key: DRILL-8118
> URL: https://issues.apache.org/jira/browse/DRILL-8118
> Project: Apache Drill
> Issue Type: Bug
> Components: Storage - MongoDB
> Affects Versions: 1.19.0
> Reporter: Charles Givre
> Assignee: Charles Givre
> Priority: Major
> Fix For: 1.20.0
>
>
> 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.
