Hello. Sorry for the late reply.
If you are free to use the latest version, Apache NiFi 1.2.0 includes very powerful processors for your use cases: QueryRecords can query record using aggregate functions such as min, max, avg. A NiFi template as an example to calculate min, max and avg from a CSV file is available here on Gist https://gist.github.com/ijokarumawak/45a609936239a0cdfc4599a576386d42 You may find Mark's blog useful for more details, "Real-Time SQL On Event Streams" https://blogs.apache.org/nifi/entry/real-time-sql-on-event Thanks, Koji On Tue, May 30, 2017 at 7:58 PM, [email protected] <[email protected]> wrote: > Hi ALL, > > I want to extract the min and max date of the input csv file.
