Study Notes
Kafka Fundamentals
- Apache Kafka is an open-source distributed event streaming platform.
- It excels in delivering high performance, scalability, and durability.
- It handles vast volumes of data in real-time, ensuring data processing speed and no message loss.
Kafka Architecture
- A Kafka cluster is made up of multiple brokers, each responsible for storing data and serving clients.
- Brokers are individual servers (physical or virtual).
- Partitions are ordered, immutable sequences of messages that are continually appended to, similar to a log file.
- Partitions allow for parallel message consumption, enabling scalability.
- A topic is a logical grouping of partitions, used for data publishing and subscription.
- Topics are multi-producer, allowing zero, one, or many producers to write data to them.
- Topics logically group messages, while partitions physically group messages on different brokers.
Kafka Use Case: Real-time Sports Statistics
- A website requires real-time statistics updates for a hypothetical World Cup with a large number of matches.
- Events (goals, bookings, substitutions) are queued and processed.
- The producer is the server that places events on the queue.
- The consumer is the server that reads events from the queue and updates the website.
Kafka Scalability Challenges
- Scaling the system to handle a large number of events from multiple matches requires distributing events across servers.
- Challenges arise in maintaining order and ensuring each event is processed only once.
Kafka Scalability Solutions
- Distributing events based on the game they are associated with ensures order within a game.
- Consumer groups allow for parallel consumption of events, with each event processed by only one consumer within the group.
- Topics enable event categorization based on the sport, allowing different websites to subscribe to specific sports events.
