----------------------------------
Summary: 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
I'm not advocating for an upgrade to Jackson 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).
