Flink Sinks

Prasanna kumar
Hi , 

I did not find out of box flink sink connector for http and SQS mechanism.  

Has anyone implemented it? 
Wanted to know if we are writing a custom sink function  , whether  it would affect semantic exactly one guarantees ?


Thanks ,
Prasanna

Prasanna,

The Flink project does not have an SQS connector, and a quick google search hasn't found one. Nor does Flink have an HTTP sink, but with a bit of googling you can find that various folks have implemented this themselves.

As for implementing SQS as a custom sink, if you need exactly once guarantees I believe you will need to limit yourself to using SQS FIFO queues, and you'll need to attach a MessageDeduplicationId to each record. SQS offers to do deduplication for you, but only supports deduplication within a 5 minute window -- which I would find too short to rely on during recovery or redeployment.

See https://stackoverflow.com/a/28111986/2000823 for more on exactly once with SQS.

Regards,
David
