A topic in Kafka is like a category or folder where messages are stored and organized. It helps group similar messages together so consumers can read them easily.

beginner

Why does Kafka use topics to organize messages?

Kafka uses topics to organize messages so that producers can send messages to specific categories, and consumers can subscribe to only the topics they care about. This keeps data organized and efficient.

How do topics help in message delivery in Kafka?

Topics help by acting as channels where messages are stored in order. Consumers read messages from topics, ensuring they get the right data in the right sequence.

beginner

What happens if messages were not organized by topics?

Without topics, messages would be mixed up, making it hard for consumers to find and process the messages they need. It would be like searching for a book in a messy library without sections.

How do topics improve scalability in Kafka?

Topics allow Kafka to split messages into partitions, which can be handled by different servers. This makes it easy to handle lots of messages and users at the same time.

What is the main purpose of a topic in Kafka?

A To display messages on screen

B To store user passwords

C To run database queries

D To organize messages into categories

Topics organize messages into categories so producers and consumers can manage data efficiently.

How do consumers use topics in Kafka?

A They send messages to topics

B They create new topics automatically

C They subscribe to topics to read messages

D They delete topics after reading

Consumers subscribe to topics to receive and process messages relevant to them.

What would happen if Kafka did not use topics?

A Messages would be mixed and hard to find

B Messages would be faster

C Messages would be encrypted automatically

D Messages would be deleted immediately

Without topics, messages would be disorganized, making it difficult to manage and consume them.

How do topics help Kafka scale to many users?

A By storing messages in a single file

B By splitting messages into partitions handled by different servers

C By limiting the number of messages

D By deleting old messages quickly

Topics can be divided into partitions, allowing Kafka to handle large amounts of data across servers.

Which of these best describes a Kafka topic?

A A message category or channel

B A user account

C A database table

D A network protocol

A Kafka topic is a category or channel where messages are grouped.
