Spark
Definition
Open-source data processing engine that runs computations in memory rather than reading and writing to disk at each step.
Use Cases
- Netflix: Recommendation engine — Netflix uses Spark to process large volumes of viewing data in real-time, enabling the recommendation system to update quickly based on user interactions. (Improved user engagement and satisfaction by providing timely and relevant content recommendations.)
Provider Equivalents
- AWS: Amazon EMR
- Azure: Azure Synapse Analytics
- GCP: Google Cloud Dataproc
- OCI: Oracle Cloud Infrastructure Data Flow
Frequently Asked Questions
- What's the difference between Spark and Hadoop?
- Spark processes data in memory, making it faster for iterative tasks, while Hadoop writes intermediate results to disk, which can be slower but more reliable for batch processing.
- When should I use Spark?
- Use Spark for tasks requiring fast data processing, like real-time analytics, machine learning, and interactive querying, especially when working with large datasets.
- How much does Spark cost?
- Costs vary based on the cloud provider and resource usage. Managed services like AWS EMR, Azure Synapse, and GCP Dataproc charge based on compute and storage resources consumed.
Spark in Cloud Architecture
Understanding Spark is important for experienced cloud architects building complex, enterprise-scale systems. Cloud architects encounter this concept when designing systems for reliability, scalability, security, and cost-efficiency across Amazon Web Services (AWS), Microsoft Azure, Google Cloud Platform (GCP), and Oracle Cloud Infrastructure (OCI).
In cloud Data, Spark is one of several foundational concepts that practitioners must master to design production-ready systems. Related concepts in the same domain include the terms listed in the See Also section below.
