Challenge

Publish the Missing Records to the `inventory_purchases` Topic.

Publish the records using an HTTP request to Confluent REST Proxy:

curl -X POST -H "Content-Type: application/vnd.kafka.json.v2+json" 
  -H "Accept: application/vnd.kafka.v2+json" 
  --data '{"records":[{"key":"apples","value":"23"},{"key":"grapes","value":"160"}]}' 
  "http://localhost:8082/topics/inventory_purchases"

We can verify that the data is in the topic with a console consumer:

kafka-console-consumer --bootstrap-server localhost:9092 --topic inventory_purchases --from-beginning --property print.key=true

Challenge

Publish the Missing Records to the `member_signups` Topic.

Publish the records using an HTTP request to Confluent REST Proxy:

curl -X POST -H "Content-Type: application/vnd.kafka.json.v2+json" 
  -H "Accept: application/vnd.kafka.v2+json" 
  --data '{"records":[{"key":"77543","value":"Rosenberg, Willow"},{"key":"56878","value":"Giles, Rupert"}]}' 
  "http://localhost:8082/topics/member_signups"

We can verify that the data is in the topic with a console consumer:

kafka-console-consumer --bootstrap-server localhost:9092 --topic member_signups --from-beginning --property print.key=true
