We find fastjson2 much faster than Jackson, especially with JDK17+.

right now we use fastjson2 (in Collector, Source, etc), but as there be an embedded jackson provided in flink, we doubt if it be worthy to migrate to using it instead. we take care of performance very much so if there be some performance benchmark please let us know... Also I'm kind of confused, so if the flink jackson have better performance, please give a link of how we shall use it now... passing JsonNode seems to be 'old style' by FLINK-32610<https://issues.apache.org/jira/browse/FLINK-32610>, but I didn't find a new usage guide...
