Hello Guha, The number of keys will be different for each event id.for example if the event id:005 it is has 10 keys then i have to flatten all those 10 keys in the final output.here there is no fixed number of keys for each event id.
001 -> 2 keys 002 -> 4 keys 003 -> 5 keys above event id has different key values combinations and different from other.i want to dynamically flatten the incoming data in the ouput s3 csv file(want to write all the flattened keys in the csv path) flatten.csv eve_id k1 k2 k3 001 abc x y eve_id, k1 k2 k3 k4 002, 12 jack 0.01 0998 eve_id, k1 k2 k3 k4 k5 003, aaa xxxx device endpoint - -- Sent from: http://apache-spark-user-list.1001560.n3.nabble.com/ --------------------------------------------------------------------- To unsubscribe e-mail: user-unsubscr...@spark.apache.org
