Resume API Example: AWS Kinesis

This example shows how to use the Resume API for consuming AWS Kinesis data streams.

It uses LocalStack to simulate the AWS Kinesis instance.

First the demo load 500 records into the data stream. Then, it consumes then in batches of 50 messages. It starts each batch at the point of last consumption. The offsets are stored in a Kafka topic.

Note: this demo runs in a container. Although it is possible to run it outside a container, doing so requires additional infrastructure. Therefore, it's not extensively covered by the documentation.

Building the demo

To build the demo and the containers:

mvn clean package && docker-compose build

Run

To run the demo:

docker-compose up -d && docker-compose logs --no-log-prefix -f example ; docker-compose down

Advanced / Manual

Launch LocalStack

docker run --rm -e SERVICES=kinesis -e DEBUG=1 -e LS_LOG=trace -it -p 4566:4566 localstack/localstack:latest

Data Load

To load the data run:

  java -Dresume.type=kafka \
    -Dresume.type.kafka.topic=aws-kinesis-offsets \
    -Dresume.action=load \
    -Daws.kinesis.streamName=sample-stream \
    -Daws-service.kinesis.instance.type=remote \
    -Daws.host=kinesis:4566 \
    -Daws.access.key=accesskey \
    -Daws.secret.key=secretkey \
    -Daws.cborEnabled=false \
    -jar /deployments/example.jar

Run the Example

java -Dresume.type=kafka \
           -Dresume.type.kafka.topic=aws-kinesis-offsets \
           -Dbootstrap.address=REPLACE-WITH-KAFKA-HOST:9092 \
           -Daws.kinesis.streamName=sample-stream \
           -Daws-service.kinesis.instance.type=remote \
           -Daws.host=REPLACE-WITH-KINESIS-HOST:4566 \
           -Daws.access.key=accesskey \
           -Daws.secret.key=secretkey \
           -Daws.cborEnabled=false \
           -Dbatch.size=50 \
           -jar /deployments/example.jar
