HI Aseem, You can run Apache Flume to consume messages from Kafka and write them to s3/HDFS in (micro batches)streaming fashion.
Writes to s3/HDFS should be in micro batches, you can do it for every message (not every sure if s3 supports append) but it won't be performant. https://flume.apache.org/ Thanks Sudev On Tue, Dec 6, 2016 at 5:14 PM Sharninder <sharnin...@gmail.com> wrote: > What do you mean by streaming way?
