Halo
The Halo Lib is a python based library utilizing Serverless technology and microservices architecture
Halo provides the following features:
Django and/or Flask development for AWS Lambda & Dynamodb
correlation id across microservices
structured json based logging
sample debug log in production
support for microservice transactions with the saga pattern
using SSM Parameter Store over Lambda env variables
Serverless Error Handling & trace id for end users
Lambda timeout management for slow HTTP responses
ootb support for Idempotent service invocations (md5)
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
