PJ Fanning resolved SPARK-42854.
--------------------------------
Resolution: Duplicate
> Jackson 2.15
> ------------
>
> Key: SPARK-42854
> URL: https://issues.apache.org/jira/browse/SPARK-42854
> Project: Spark
> Issue Type: Improvement
> Components: Input/Output
> Affects Versions: 3.4.1
> Reporter: PJ Fanning
> Priority: Major
>
> I'm not advocating for an upgrade to [Jackson
> 2.15|https://github.com/FasterXML/jackson/wiki/Jackson-Release-2.15].
> 2.15.0-rc1 has just been released and 2.15.0 should be out soon.
> There are some security focused enhancements including a new class called
> StreamReadConstraints. The defaults on
> [StreamReadConstraints|https://javadoc.io/static/com.fasterxml.jackson.core/jackson-core/2.15.0-rc1/com/fasterxml/jackson/core/StreamReadConstraints.html]
> are pretty high but it is not inconceivable that some Spark users might need
> to relax them. Parsing large strings as numbers is sub-quadratic, thus the
> default limit of 1000 chars or bytes (depending on input context).
> When the Spark team consider upgrading to Jackson 2.15 or above, you might
> also want to consider adding some way for users to configure the
> StreamReadConstraints.
