• Language should be mature and have a mature kafka client

Kafka Benchmarking:

• The Language should be performant
• Language should support concurrency

Language Go or Node are preferable.

Document Architecture decisions using ADR TOOLS If you cannot install the tools then use the provided template

• single receiving topic enter the persist-and-validate consumer:
  • This consumer persists all webhooks and validates them afterward.
  • Then if it is invalid it will not send it on to the next consumer.
  • Valid uuid's are passed onto the next topic

• Unique URL's should be persisted and monitored
  • When a message arrived with a new URL this URL is added to the ENDPOINTS table
  • This URL is monitored periodically for availability

• single delivering topic from the webhooks received consumer will be dispatched here:
  • This consumer will poll the URL provided for the webhooks and send the webhooks on to the next stage

1. Create exported functions to be passed to a consumer and create unit tests for these functions.

1. Spin up the app with a consumer and producer and connect to a kafka cluster
2. Receive messages and process them into the database
3. Retrieve successfully stored messages and validate the contents
   1. Is valid url for urls in collection
   2. Is a valid json body (can be json parsed - all we can do really)
4. Post successfully validated webhooks concurrently for all urls provided
5. Create a container to receive webhooks and test response
   1. Status - 200
   2. Status - 404
   3. Status - 401
   4. Status - 301
   5. Status - 500
