As noted in DRILL-5949, options like this should be part of the plugin
config (as in CSV), not session options. For now, let's leave them as session
options and I'll migrate them to plugin config options along with the others.
> Add non-numeric support for JSON processing
> -------------------------------------------

> Key: DRILL-5919
> URL: https://issues.apache.org/jira/browse/DRILL-5919
> Project: Apache Drill
> Issue Type: Improvement
> Components: Storage - JSON
> Affects Versions: 1.11.0
> Reporter: Volodymyr Tkach
> Assignee: Volodymyr Tkach
> Labels: doc-impacting
> Fix For: Future
>
>
> Add session options to allow drill working with non standard json strings
> number literals like: NaN, Infinity, -Infinity. By default these options will
> be switched off, the user will be able to toggle them during working session.
> *For documentation*
> 1. Added two session options {{store.json.reader.non_numeric_numbers}} and
> {{store.json.reader.non_numeric_numbers}} that allow to read/write NaN and
> Infinity as numbers. By default these options are set to false.
> 2. Extended signature of {{convert_toJSON}} and {{convert_fromJSON}}
> functions by adding second optional parameter that enables read/write NaN and
> Infinity.
> For example:
> {noformat}
> select convert_fromJSON('{"key": NaN}') from (values(1)); will result with
> JsonParseException, but
> select convert_fromJSON('{"key": NaN}', true) from (values(1)); will parse
> NaN as a number.
> {noformat}
