> 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.
