Subject s3 read while writing inside sink function
Date Fri, 31 Mar 2017 04:12:00 GMT
Hi fellow Flink enthusiasts,

I am trying figure out a recommended way to read s3 data  while  I am trying to write to s3
using BucketingSink.

BucketingSink<String> s3Sink = new BucketingSink<String>("s3://" + entityBucket
+ "/")
        .setBucketer(new EntityCustomBucketer())
        .setWriter(new StringWriter<String>())

The issue is that I want to write to S3 based on a condition check on the filename already
existing there.
I wanted to bake this check within the sink itself, any clue on what is needed for this?
