> ConsumeKinesisStream support for Sub Sequence Number

> Key: NIFI-14394
> URL: https://issues.apache.org/jira/browse/NIFI-14394
> Project: Apache NiFi
> Issue Type: Improvement
> Components: Extensions
> Affects Versions: 2.3.0
> Reporter: Dariusz Seweryn
> Priority: Major

> ConsumeKinesisStream supports "Output Strategy" of "Use Wrapper" which wraps
> message data and metadata into record content.
> Currently metadata includes:
> * stream
> * shardId
> * sequenceNumber
> * partitionKey
> * approximateArrival
> What it does not include is Sub Sequence Number which is assigned to messages
> that [are aggregated by the Amazon's Kinesis Producer
> Library|https://docs.aws.amazon.com/streams/latest/dev/kinesis-producer-adv-aggregation.html]
> making them indistinguishable by evaluating metadata.
> Proposal is to add to wrapped metadata:
> * subSequenceNumber — a long
> * shardUniqueId — a String formed as {{String.format("%s%020d",
> sequenceNumber, subSequenceNumber)}} which could be useful for uniquely
> identifying messages identifying order using a single comparison
