        # Halo
        
        The **Halo** Lib is a python based library utilizing [**Serverless**](https://logz.io/blog/serverless-vs-containers/) technology and [**microservices architecture**](http://blog.binaris.com/your-guide-to-migrating-existing-microservices-to-serverless/) 
        <p/>Halo provides the following features:
        
        -  Flask development for AWS Lambda & Dynamodb
        -  [correlation id across microservices](https://theburningmonk.com/2017/09/capture-and-forward-correlation-ids-through-different-lambda-event-sources/)
        -  [structured json based logging](https://theburningmonk.com/2018/01/you-need-to-use-structured-logging-with-aws-lambda/)
        -  [sample debug log in production](https://theburningmonk.com/2018/04/you-need-to-sample-debug-logs-in-production/)
        -  [support for microservice transactions with the saga pattern](https://read.acloud.guru/how-the-saga-pattern-manages-failures-with-aws-lambda-and-step-functions-bc8f7129f900)
        -  [using SSM Parameter Store over Lambda env variables](https://hackernoon.com/you-should-use-ssm-parameter-store-over-lambda-env-variables-5197fc6ea45b)
        -  [Serverless Error Handling & trace id for end users](https://aws.amazon.com/blogs/compute/error-handling-patterns-in-amazon-api-gateway-and-aws-lambda/)
        -  [Lambda timeout](https://blog.epsagon.com/best-practices-for-aws-lambda-timeouts) management for [slow HTTP responses](https://theburningmonk.com/2018/01/aws-lambda-use-the-invocation-context-to-better-handle-slow-http-responses/)
        -  [ootb support for Idempotent service invocations (md5)](https://cloudonaut.io/your-lambda-function-might-execute-twice-deal-with-it/)
        
        If you are building a Python web app running on AWS Lambda (Django or Flask), use this library to manage api transactions:
        
        ```
                    sagax = load_saga("test", jsonx, schema)
                    payloads = {"BookHotel": {"abc": "def"}, "BookFlight": {"abc": "def"}, "BookRental": {"abc": "def"},
                                "CancelHotel": {"abc": "def"}, "CancelFlight": {"abc": "def"}, "CancelRental": {"abc": "def"}}
                    apis = {"BookHotel": self.create_api1, "BookFlight": self.create_api2, "BookRental": self.create_api3,
                            "CancelHotel": self.create_api4, "CancelFlight": self.create_api5, "CancelRental": self.create_api6}
                    try:
                        self.context = Util.get_lambda_context(request)
                        ret = sagax.execute(self.req_context, payloads, apis)
                        return {"saga": "good"}, 200
                    except SagaRollBack as e:
                        return {"saga": "bad"}, 500
        ```
