----------------------------------
Summary: [FLIP-171] DynamoDB implementation of Async Sink
Key: FLINK-24229
URL: https://issues.apache.org/jira/browse/FLINK-24229
Project: Flink
Issue Type: New Feature
Components: Connectors / Common
Reporter: Zichen Liu
Assignee: Zichen Liu
Fix For: 1.15.0
h2. Motivation
*User stories:*
As a Flink user, I’d like to use Kinesis Firehose as sink for my data pipeline.
*Scope:*
* Implement an asynchronous sink for Kinesis Firehose by inheriting the
AsyncSinkBase class. The implementation can for now reside in its own module in
flink-connectors. The module and package name can be anything reasonable e.g.
{{flink-connector-aws-kinesis}} for the module name and
{{org.apache.flink.connector.aws.kinesis}} for the package name.
* The implementation must use [the Kinesis Java
Client|https://docs.aws.amazon.com/AWSJavaSDK/latest/javadoc/com/amazonaws/services/kinesis/AmazonKinesisClient.html].
* The implementation must allow users to configure the Kinesis Client, with
reasonable default settings.
* Implement an asynchornous sink writer for Firehose by extending the
AsyncSinkWriter. The implementation must deal with failed requests and retry
them using the {{requeueFailedRequestEntry}} method. If possible, the
implementation should batch multiple requests (PutRecordsRequestEntry objects)
to Firehose for increased throughput. The implemented Sink Writer will be used
by the Sink class that will be created as part of this story.
* Unit/Integration testing. Use Kinesalite (in-memory Kinesis simulation). We
already use this in {{KinesisTableApiITCase}}.
* Java / code-level docs.
* End to end testing: add tests that hits a real AWS instance. (How to best
donate resources to the Flink project to allow this to happen?)
