Abhishek Dixit updated SPARK-28124:
-----------------------------------
Description:
Using FileStreamSource to read files from a s3 bucket has problems both in
terms of costs and latency:
* *Latency:* Listing all the files in s3 buckets every microbatch can be both
slow and resource intensive.
* *Costs:* Making List API requests to s3 eery microbatch can be costly.
The solution is to use Amazon Simple Queue Service (SQS) which lets you find
new files written to s3 bucket without the need to list all the files every
microbatch.
s3 buckets can be configured to send notification to an Amazon SQS Queue on
Object Create / Object Delete events. For details see AWS documentation here
[Configuring s3 Event
Notifications|https://docs.aws.amazon.com/AmazonS3/latest/dev/NotificationHowTo.html]
We can leverage this to find new files written to s3 bucket by reading
notifications from SQS queue instead of listing files every microbatch.
