Data Types

The types of data you can store and analyze play a major role in your choice between data lakehouse vs data warehouse. A data warehouse focuses on structured data, such as tables from transactional systems or spreadsheets. Some modern warehouses support semi-structured data, but they struggle with unstructured formats like images, videos, or raw logs.

A data lakehouse, on the other hand, supports a much broader range of data types. You can store structured, semi-structured, and unstructured data in one place. This flexibility allows you to run advanced analytics, machine learning, and real-time processing on diverse datasets.

• Data lakehouses support:
  • Structured data (tables, relational databases)
  • Semi-structured data (JSON, XML)
  • Unstructured data (text, images, audio, video)
• Data warehouses primarily support:
  • Structured data
  • Some semi-structured data

You gain a significant advantage with a data lakehouse if your business needs to analyze raw logs, multimedia files, or data from IoT devices. If your focus remains on traditional business reporting, a data warehouse may meet your needs.

Storage

Data storage methods differ greatly between data lakehouse vs data warehouse. A data warehouse stores data in a highly structured format, often using proprietary storage systems optimized for fast queries and reporting. This approach delivers high performance for business intelligence but can become expensive as your data grows.

A data lakehouse uses scalable, cost-effective storage that supports structured, semi-structured, and unstructured data. Technologies like Delta Lake or Apache Iceberg enable features such as ACID transactions, schema evolution, and data versioning. You can store large volumes of raw data at a lower cost and process it as needed for analytics or machine learning.

You can reduce data ingest compute costs by up to 95% with a data lakehouse compared to a traditional data warehouse. Modern data lakes offer interoperability and lower total ownership costs, making them attractive for organizations with large and diverse datasets.
