Specifications for a notification system for a bank app using Kafka, Spring Boot, and Java 11

Here are some functional and technical specifications for a notification system for a bank app using Kafka, Spring Boot, and Java 11:

Functional Specifications:

• The notification system should be able to send real-time notifications to users of the bank app about various events such as account transactions, account balance updates, and promotional offers.

• Users should be able to customize their notification preferences, including the types of notifications they want to receive and the frequency of notification delivery.

• The notification system should be able to handle high volume and high throughput, as it will be serving a large number of users.

• The notification system should be reliable and should be able to handle failures and recover gracefully.

Technical Specifications:

• The notification system should be built using Kafka, a distributed streaming platform, as the messaging system. Kafka will be used to publish and subscribe to notification messages.

• The notification system should be implemented using Spring Boot, a Java-based framework for building microservices. Spring Boot will be used to build the REST APIs for the notification system and to manage the dependencies and configurations.

• The notification system should be developed using Java 11, the latest version of the Java programming language.

• The notification system should store user notification preferences and other relevant data in a database. A suitable database, such as MySQL or MongoDB, should be selected based on the size and complexity of the data.

• The notification system should have a user-friendly interface for managing notification preferences and viewing notification history. This interface can be implemented as a web application or as a mobile app, depending on the target platform.
