Study Notes
Lakehouse Architecture
- Combines advantages of data lakes and data warehouses into a single platform.
- Designed to overcome limitations and complexity of traditional business intelligence (BI) and machine learning (ML) systems.
- Utilizes low-cost object storage, leveraging modern system design principles.
Features of Lakehouse
- Supports various data-related tasks, including BI, SQL analytics, data science, and ML on one platform.
- Databricks Unified Data Analytics Platform exemplifies lakehouse architecture.
- Open-source file formats like Delta Lake facilitate building custom lakehouse systems.
Benefits of Lakehouse Approach
- Users can incrementally enhance data quality before it becomes available for analysis.
- Streamlines access to data using industry-standard tools like Spark, Python, and R.
- Facilitates collaboration and shared data use between data scientists and analysts.
Challenges in Data Science
- Data scientists often face barriers to productivity due to infrastructure management and collaboration difficulties.
- A conducive collaborative environment for data exploration, visibility, and reproducibility is essential but challenging to achieve.
- Existing data warehouse solutions are constrained by clustered storage and limited scalability.
Comparison of Data Approaches
- Data warehousing typically supports structured data, while lakehouses and data lakes can handle structured, semi-structured, and unstructured data.
- Data lakes provide high scalability and flexibility that traditional data warehouses lack.
- Lakehouse approach is newer compared to data warehouses (1980s) and data lakes (2011), focusing on addressing modern data challenges.
Future-Proofing Data Management
- Data warehousing lacks the capabilities for predictions, real-time data, scalable architectures, and handling raw data.
- Lakehouses address the demand for dynamic systems capable of processing diverse data types efficiently.
Cost and Vendor Lock-In
- Traditional data warehouses may lead to vendor lock-in, complicating the use of proprietary data formats across different systems.
- Lakehouses aim to provide more accessible and cost-effective data management solutions without restrictive formats.
