海外TECH	DEV Community	Decouple your DAGs with an event-driven architecture on AWS	https://dev.to/aws-builders/decouple-your-dags-with-an-event-driven-architecture-on-aws-bk	Decouple your DAGs with an event driven architecture on AWS IntroductionApplying domain driven design and an event driven architecture to the orchestration of our services has given our teams some very practical benefits in their day to day work on development and support The ProblemUp until recently we ran our main scoring job in one big DAG running in Airflow This DAG calls services developed and maintained by at least separate teams With this setup we were tightly coupling our systems our processes on call support and our development and technology choices In practice here are a couple of real world problems we were running into The upstream team had several variations of their steps within the DAG Each variation needed to have our teams steps copied and maintained in separate DAGs Decoupling allows us to keep all our steps in a single DAG and to know where exactly our services are being orchestrated from The decision to use Airflow was made by the upstream team as it made sense for their skills and technologies Decoupling will also allow us to use a technology that may be better suited to our teams skills and technologies For example we could move to Step Functions if we wanted We will not be bound to another team or domains technology choices In addition to being on a mailing list for all alerts from the DAG having to troubleshoot any failure may involve going through the larger DAG While this may seem minor situations like these can take a toll on a developer s productivity Having our own separate DAG allows us to focus on our own services The Solution Domain Driven DesignThe first step was to identify the different domains represented within the larger DAG From the outside these may seem simple The core services can be easy to identify but the boundaries are harder to identify Where does one domain end and another begin Our criteria for each domain was resolved around which team supported the service called In addition it was agreed the upstream domain was responsible for publishing an event when a material step in the DAG had completed The downstream domain was responsible to consume that event Using these guidelines we were able to split the DAG out into separate domains Communication between domainsWe knew we needed to communicate between domains This communication would involve more than just a marker to say that an event had happened We also needed to pass some parameters between domains These parameters were necessary to the execution of the end to end flow and needed to be passed from domain to domain The term event driven has become ubiquitous in modern software development but what does it mean What exactly is an event According to AWSAn event is a change in state or an update like an item being placed in a shopping cart on an e commerce website Events can either carry the state the item purchased its price and a delivery address or events can be identifiers a notification that an order was shipped Using this definition we would able to use the event to pass information from one domain to another Technical solutionWhile our Airflow clusters are hosted on premise we decided early on that we wanted to use AWS services to publish and subscribe to events We have an internal goal to host our services on AWS and to use a serverless service where we can Ultimately the SNS Fanout to SQS pattern fitted well to our requirements For more information on this pattern see this post on the AWS blog This pattern allows us to separate out the publisher and subscriber into distinct services The upstream service publishes an SNS topic with the event details Each downstream service owns a separate SQS queue that subscribes to that topic A JSON document can be passed between both services to communicate any necessary parameters This is the upstream Airflow DAG Once it has passed a certain point a JSON document is passed via API Gateway to an SNS topic SNS immediately informs all subscribers that a new event has been received The JSON document is passed along to all subscribers In the downstream domain an FIFO SQS queue is subscribed to the SNS topic The first step in the downstream DAG polls the SQS queue on a regular interval for messages using API Gateway If a message is on the queue the step validates the message to see if it is properly formed If so it kicks off the DAG with the parameters from the JSON document and deletes the message from the queue via API Gateway An obvious advantage of this design is that when multiple SQS queues can subscribe to the SNS topic without impacting on the upstream DAG or other subscribed SQS queues Note No Lambdas were harmed in the development of this application Serverless is about more than Lambda CDKWe used CDK to deploy our services This construct is very similar to what we used aws solutions constructs aws sns sqs v lang pythonHowever you will need to split out the SQS queue into the downstream domains code base parameterized with the name of the SNS topic This is still a manual step for us but we are investigating the use of AWS Systems Manager Parameter Store to store and retrieve the name of relevant topic within the CI CD process SummaryUtilizing AWS services to facilitate an event driven architecture has been a game changer for us It is a relatively simple change in our case but provides several powerful benefits To find out
