SchedulerApp

Job scheduling service that can streamline credit card statement generation.

Download kafka and extract it.

Run Kafka By using CLI Commands

• Step 1. Run Zookeeper Server

$ bin/zookeeper-server-start.sh config/zookeeper.properties

on windows:
kafka-3.7.1>bin\windows\zookeeper-server-start.bat .\config\zookeeper.properties

• Step 2. Run Kafka Server

$ bin/kafka-server-start.sh config/server.properties

on windows:
kafka-3.7.1>bin\windows\kafka-server-start.bat .\config\server.properties

• Step 3. Run the producer server. In this app, a scheduler will fetch the transaction details of users whose statements are to be generated today and send them to the Kafka server for further processing.

producer>mvn spring-boot:run

• Step 4. Run the consumer server. Receives the transaction details of users from the Kafka server and generates the card statement document for each user.

consumer>mvn spring-boot:run
