Assignee: Vinay (was: Suneel Marthi)
> DynamoDB/Kinesis Change Capture using Delta Streamer
>
>
> Key: HUDI-310
> URL: https://issues.apache.org/jira/browse/HUDI-310
> Project: Apache Hudi
> Issue Type: New Feature
> Components: DeltaStreamer
>Reporter: Vinoth Chandar
>Assignee: Vinay
>Priority: Major
>
> The goal here is to do CDC from DynamoDB and then have it be ingested into S3
> as a Hudi dataset
> Few resources:
> # DynamoDB Streams
> [https://docs.aws.amazon.com/amazondynamodb/latest/developerguide/Streams.html]
> provides change capture logs in Kinesis.
> # Walkthrough
> [https://docs.aws.amazon.com/amazondynamodb/latest/developerguide/Streams.KCLAdapter.Walkthrough.html]
> Code [https://github.com/awslabs/dynamodb-streams-kinesis-adapter]
> # Spark Streaming has support for reading Kinesis streams
> [https://spark.apache.org/docs/2.4.4/streaming-kinesis-integration.html] one
> of the many resources showing how to change the Spark Kinesis example code to
> consume dynamodb stream
> [https://medium.com/@ravi72munde/using-spark-streaming-with-dynamodb-d325b9a73c79]
> # In DeltaStreamer, we need to add some form of KinesisSource that returns a
> RDD with new data everytime `fetchNewData` is called
> [https://github.com/apache/incubator-hudi/blob/master/hudi-utilities/src/main/java/org/apache/hudi/utilities/sources/Source.java]
> . DeltaStreamer itself does not use Spark Streaming APIs
> # Internally, we have Avro, Json, Row sources that extract data in these
> formats.
> Open questions :
> # Should this just be a KinesisSource inside Hudi, that needs to be
> configured differently or do we need two sources: DynamoDBKinesisSource (that
> does some DynamoDB Stream specific setup/assumptions) and a plain
> KinesisSource. What's more valuable to do , if we have to pick one.
> # For Kafka integration, we just reused the KafkaRDD in Spark Streaming
> easily and avoided writing a lot of code by hand. Could we pull the same
> thing off for Kinesis? (probably needs digging through Spark code)
> # What's the format of the data for DynamoDB streams?
>
>
> We should probably flesh these out before going ahead with implementation?
