             Summary: Use simdjson-java in JSON related UDFs
                 Key: SPARK-47801
                 URL: https://issues.apache.org/jira/browse/SPARK-47801
             Project: Spark
          Issue Type: Improvement
          Components: Spark Core
    Affects Versions: 3.5.2
            Reporter: Zheng Shao


JSON parsing speed is important.

Right now, functions like GET_JSON_OBJECT, FROM_JSON are slow because they 
don't use [https://github.com/simdjson/simdjson-java]

 

We should consider adopting [https://github.com/simdjson/simdjson-java] for 
those UDFs.
