> Allow FlinkKinesisConsumer to adapt for AWS DynamoDB Streams
> ------------------------------------------------------------
>
> Key: FLINK-4582
> URL: https://issues.apache.org/jira/browse/FLINK-4582
> Project: Flink
> Issue Type: New Feature
> Components: Kinesis Connector, Streaming Connectors
> Reporter: Tzu-Li (Gordon) Tai
> Assignee: Ying Xu
> Priority: Major
> Labels: pull-request-available
>
> AWS DynamoDB is a NoSQL database service that has a CDC-like (change data
> capture) feature called DynamoDB Streams
> (http://docs.aws.amazon.com/amazondynamodb/latest/developerguide/Streams.html),
> which is a stream feed of item-level table activities.
> The DynamoDB Streams shard abstraction follows that of Kinesis Streams with
> only a slight difference in resharding behaviours, so it is possible to build
> on the internals of our Flink Kinesis Consumer for an exactly-once DynamoDB
> Streams source.
> I propose an API something like this:
> {code}
> DataStream dynamoItemsCdc =
> FlinkKinesisConsumer.asDynamoDBStream(tableNames, schema, config)
> {code}
> The feature adds more connectivity to popular AWS services for Flink, and
> combining what Flink has for exactly-once semantics, out-of-core state
> backends, and queryable state with CDC can have very strong use cases. For
> this feature there should only be an extra dependency to the AWS Java SDK for
> DynamoDB, which has Apache License 2.0.
