AWS DataOps Development Kit (DDK)Packages 🗳️NPMPypiThe AWS DataOps Development Kit is an open source development framework for customers that build data workflows and modern data architecture on AWS.Based on theAWS CDK, it offers high-level abstractions allowing you to build pipelines that manage data flows on AWS, driven by DevOps best practices.  The framework is extensible, you can add abstractions for your own data processing infrastructure or replace our best practices with your own standards. It's easy to share templates, so everyone in your organisation can concentrate on the business logic of dealing with their data, rather than boilerplate logic.TheDDK Coreis a library of CDK constructs that you can use to build data workflows and modern data architecture on AWS, following our best practice. The DDK Core is modular and extensible, if our best practice doesn't work for you, then you can update and share your own version with the rest of your organisation by leveraging a privateAWS Code Artifactrepository.You can compose constructs from the DDK Core into aDDK App.  Your DDK App can also add contain constructs from the CDK Framework or theAWS Construct Library.OverviewFor a detailed walk-through, check out ourWorkshopor
take a look atexamples.Build Data PipelinesOne of the core features of DDK is ability to create Data Pipelines. A DDKDataPipelineis a chained series of stages. It automatically “wires” the stages together usingAWS EventBridge Rules.DDK comes with a library of stages, however users can also create their own based on their use cases,
and are encouraged to share them with the community.Let's take a look at an example below:...firehose_s3_stage=FirehoseToS3Stage(self,"ddk-firehose-s3",bucket=ddk_bucket,data_output_prefix="raw/",)sqs_lambda_stage=SqsToLambdaStage(scope=self,id="ddk-sqs-lambda",code=Code.from_asset("./lambda"),handler="index.lambda_handler",layers=[LayerVersion.from_layer_version_arn(self,"ddk-lambda-layer-wrangler",f"arn:aws:lambda:{self.region}:336392948345:layer:AWSSDKPandas-Python39:1",)])(DataPipeline(scope=self,id="ddk-pipeline").add_stage(firehose_s3_stage).add_stage(sqs_lambda_stage))...First, we import the required resources from the aws_ddk_core library, including the two stage constructs:FirehoseToS3Stage()andSqsToLambdaStage().
These two classes are then instantiated and the delivery stream is configured with the S3 prefix (raw/).
Finally, the DDK DataPipeline construct is used to chain these two stages together into a data pipeline.Complete source code of the data pipeline above can be found inAWS DDK Examples - Basic Data PipelineOfficial ResourcesWorkshopDocumentationAPI ReferenceExamplesGetting HelpThe best way to interact with our team is through GitHub.  You can open an issue and choose from one of our templates for bug reports, feature requests, or documentation issues.  If you have a feature request, don't forget you can search existing issues and upvote or comment on existing issues before creating a new one.ContributingWe welcome community contributions and pull requests.  Please seeCONTRIBUTING.mdfor details on how to set up a development
environment and submit code.Other Ways to SupportOne way you can support our project is by letting others know that your organisation uses the DDK.
