Apache Flink vs Apache Spark: Difference Table
| Aspects | Apache Flink | Apache Spark |
|---|---|---|
| Processing Style | Primarily stream processing, with batch processing capabilities | Primarily batch processing, with real-time stream processing through Spark Streaming |
| Focus | Low-latency, real-time analytics | High-throughput, large-scale data processing |
| State Management | Advanced state management with exactly-once consistency guarantees | Resilient Distributed Datasets (RDDs) for fault tolerance |
| Windowing | Extensive capabilities for event-time and processing-time-based windows, session windows, and custom window functions (designed for streams) | Limited to time-based windows (less versatile for streams) |
| Language Support | Java, Scala, Python (Python support less mature) | Scala, Java, Python, R |
| Ecosystem & Community | Growing ecosystem, but less extensive than Spark’s | Comprehensive and well-developed ecosystem with a wide range of connectors, libraries, and tools |
| Strengths | Real-time analytics, complex event processing (CEP), low-latency requirements | Batch processing, machine learning (MLlib library), diverse language support |
| Ideal Use Cases | Real-time fraud detection, sensor data analysis, stock price analysis | ETL (Extract, Transform, Load) jobs, data cleaning, large-scale batch analytics |
