--------------------------------
Summary: Support json_length function
Key: SPARK-47519
URL: https://issues.apache.org/jira/browse/SPARK-47519
Project: Spark
Issue Type: New Feature
Components: SQL
Affects Versions: 4.0.0
Reporter: Qian Sun
At the moment, we don't support json_length built-in function in apache spark.
This function is supported by
# presto: [https://prestodb.io/docs/current/functions/json.html#json_size]
# clickhouse:
[https://clickhouse.com/docs/en/sql-reference/functions/json-functions#jsonlengthjson-indices_or_keys]
This allows naive users to directly get json length with a built-in json
function.
