bballreport_lambdas

Collection of FaaS Python scripts to be used with AWS lambda to put/get/update items in DynamoDB

Contents

• Data creation functions

  • All scripts with filename postfix handler are for accessing information from the MySportsFeeds website and creating a data model more tenable to my data access patterns.
  • These functions require you to have an active subscriptions to MySportsFeeds. You will need to set a Lambda environment variable "api_key": "YOUR-KEY-HERE"
  • To create your own DynamoDB table and wire it up to work with these, create a table of your choice and change the tablename within the script of your choosing
    • If you plan to use indexes for alternate access patterns, consult the AWS documentation on Global Secondary Indexes in DynamoDB to become more comfortable with them
  • All data creation lambdas will need BatchWriteItem, PutItem, and UpdateItem permissions on the DynamoDB service

• Data access functions

  • All scripts pre-fixed with get are for accessing information within DynamoDB
  • All data access lambdas will need Query permissions on the DynamoDB service

Wiring Lambdas to API Gateway

1. Create an instance of the API Gateway service using either the AWS CLI or Console
2. Create resources for the following suggested topics:
   • player
   • games
   • team
3. Create methods on those resources and for each:
   1. Specify the lambda functions to hook up
   2. Force the requried QueryString parameters and select whichever authorizer you plan to use for validation
   3. Create a mapping within the integration to map QueryString -> {name of event parameter(s) within the functions}
4. Optionally secure your API by referencing the various methods found in the API Gateway documentation
5. Publish your API and access using whichever requests library you prefer passing relevant QueryStrings and authorization information
