i need to convert those data like below. 07-08-2017,r1c2,r2c2,r3c2 07-08-2017,r1c3,r2c3,r3c3 07-08-2017,r1c4,r2c4,r3c4 07-08-2017,r1c5,r2c5,r3c5 i have tried those with nifi looping concept.It fails while stores overall input in memory leads performance slower. i have asked that into my best friend(google) then it shows some ExecuteScript processor available in nifi for processing my requirement. Am new to that jython/groovy script but i have tried following script but end result not like my expected result. https://stackoverflow.com/questions/10507104/how-to-do-row-to-column-transposition-of-data-in-csv-table/10507199#10507199 i need to convert those data with respect to my requirement in NiFi without using any external dependencies. Can anyone guide me way to achieve my requirement?
