Deep Dive on Calendar Receipts and how they are gathered for Millions of Events

AWS Calendar Invite Server - What's behind the Calendar Receipt Workflow
  • What is the core function of the AWS Calendar Invite Server? The AWS Calendar Invite Server facilitates the sending of calendar invites, particularly for events like MLB games, and, importantly, collects detailed receipt data for these invites. It's designed to manage both bulk and individual invite distributions.

  • What is API number one, and how does it initiate a calendar invite? API number one is a "one-click embedded calendar invite button" used on webpages. When activated for a specific event (e.g., a baseball game), it triggers a series of AWS Lambda functions. These Lambdas reconstruct the calendar invite data, which is initially stored disassembled in a DynamoDB database, into a complete calendar invite.

  • How does the server actually send out calendar invites? After the Lambda functions reconstruct the calendar invite, it's sent out using Amazon's Simple Email Service (SES). The system builds a "raw calendar invite," which is then distributed via SES to the intended recipients.

  • How does the AWS Calendar Invite Server collect receipt data for sent invites? When recipients interact with the individual calendar invites they receive (e.g., by accepting or declining), their email client sends data back to the AWS API Gateway. This receipt data is then collected into an S3 bucket, processed by another series of Lambda functions, and finally stored back into a DynamoDB database.

  • What kind of data is stored in DynamoDB related to calendar invites? Initially, the "articulated calendar invite data" is stored in a disassembled, raw form within DynamoDB. After invites are sent and receipts are collected, the individual calendar receipt data, potentially millions of them, is also stored in DynamoDB.

  • What AWS services are key to the operation of the calendar invite server? Several AWS services are critical: DynamoDB for data storage, Lambda for processing and reconstruction of invites and receipts, S3 for temporary storage of receipt data, and the Simple Email Service (SES) for sending the actual calendar invites. The API Gateway is used to receive incoming receipt data.

  • How is the collected calendar receipt data utilized or visualized? The collected receipt data, which can amount to millions of entries, is used to provide detailed calendar receipt information. This data is then summarized and visualized through various other APIs, mentioned explicitly as API number three, API number six, and APIs four and five, allowing for analysis of recipient interactions.

  • What is the "intellectual property" mentioned in relation to collecting receipt data? The intellectual property, as highlighted, revolves around the process of how API 1 extracts the calendar invite data from DynamoDB, the series of Lambdas that reconstruct and send the invite via SES, and then the subsequent collection of recipient interaction data (receipts) via the API Gateway into S3, processing with Lambdas, and storing back into DynamoDB for detailed visualization.
