Comparing more than one files in nifi

[karthi keyan]

Hi all,

Need to compare more than one files/Datasource and combine those the data?

example:
File 1 - id(primary key),name,age
File 2  - id, City,Country
File 3  - id , product,cost

I want to compare the above files with the primary id and combine the
result as

*id,name,age,product,cost,city,country *

It can be achieved by joining them in RDBMS to compare and combine the
data,But i want to do with Apache Nifi.

Is there any possibilities in Apache NIFI ?

any help appreciated.

Thanks,
Karthik
