--------------------------------------
Summary: Support json_array_length function
Key: SPARK-31008
URL: https://issues.apache.org/jira/browse/SPARK-31008
Project: Spark
Issue Type: New Feature
Components: SQL
Affects Versions: 3.0.0
Reporter: Rakesh Raushan
At the moment we don't support json_array_length function in spark.
This function is supported by
a.) PostgreSQL -> [https://www.postgresql.org/docs/9.3/functions-json.html]
b.) Presto -> [https://prestodb.io/docs/current/functions/json.html]
c.) redshift ->
[https://docs.aws.amazon.com/redshift/latest/dg/JSON_ARRAY_LENGTH.html]
This allows naive users to directly get array length with a well defined json
function.
