Databricks Lakehouse Architecture: An Overview
Key Components of Lakehouse Architecture
Data Ingestion Layer
Data is ingested from different sources:
- Databases
- APIs
- Streaming systems
- IoT devices
Supports both:
- Batch ingestion
- Real-time streaming
Storage Layer (Data Lake)
All data is stored in a centralized data lake.
Key Characteristics:
- Cost-effective storage solution
- Supports all types of data
- Scalable
Examples:
- Cloud storage (S3, ADLS)
Processing Layer
Data is processed through distributed computing system.
Technologies:
- Apache Spark
- SQL engines
