--------------------------------

Hi: 

[~tzulitai]  [~mingdaoy]  

I'm following up on this JIRA as we currently have a production use case which 
requires injecting the DynamoDB changelogs into Kafka. Interested in 
contributing to related efforts as well. I have raised a request on the dev 
mailing list ([raw 
message|https://mail-archives.apache.org/mod_mbox/flink-dev/201806.mbox/raw/%3CCAJ5M44_FC8u713SWHCZx02FtEfyM8RpDF%2BeTNS9W%3DTC4JkVicQ%40mail.gmail.com%3E])
 

 

Thanks.

> 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.
