Mastering Big Data with PySpark



- **High throughput:** Kafka can deliver messages at network-limited throughput using a cluster with minimal latency.
- **Scalability:** The platform scales smoothly to accommodate clusters with up to a thousand brokers, managing trillions of messages daily and petabytes of data.
- **Storage:** Kafka securely stores streams of data in a distributed, durable, and fault-tolerant cluster.
- **Availability:** It ensures robust connectivity across separate clusters, spanning various geographic locations.

# Kafka architecture

Kafka operates as an event streaming platform, integrating three critical capabilities for end-to-end event streaming solutions:

- **Publishing and subscribing:** It allows writing (publishing) and reading (subscribing) streams of events, facilitating continuous data import/export from different systems.
- **Persistent storage:** Kafka stores streams of events reliably and durably, allowing data retention for as long as needed.
- **Event processing:** It processes streams of events in real-time and retrospectively.

## How Kafka works

Kafka's core components involve **brokers** (servers) that manage **topics**, which are streams of events. Topics are partitioned and replicated across multiple brokers for fault tolerance and scalability. Each event record encapsulates key, value, timestamp, and optional metadata.

- **Producers:** These client applications publish events to Kafka topics.
- **Consumers:** Applications retrieve data from these topics. Consumers can manage their progress via offsets, while Kafka organizes consumers into logical groups called consumer groups for parallel data processing.

The communication within Kafka occurs through a high-performance TCP network protocol, allowing seamless interaction between producers, consumers, brokers, and topics. Understanding these fundamental concepts is crucial for effectively utilizing Kafka in handling real-time data streams and distributed event processing.
