Data Lakehouse vs Data Mesh Data Lakehouse is a data management solution like a database , datawarehouse or a data lake. A simple definition of a lakehouse will be the " best of both datawarehouses and data lakes". For technical folks it is data lake plus a table format (apache hudi, apace iceberg or delta lake). Lakehouse can be implemented in various ways and many vendors have done it in their own way. But some common requirements to satisfy a lakehouse architecture are 1. Handle all types of data 2. Faster data discovery & exploration 3. Reduced ETL 4. Reduced data redundancy 5. Metadata management 6. Use open file formats 7. Decoupled storage & compute 8. Cost effective 9. Integrated security & governance controls 10. Handle multiple use cases. (BI, ML) Databricks Lakehouse, Aws redshift spectrum, Azure Synapse analytics, Dremio are some of the well known lakehouse solutions. Data Mesh: Data Mesh on the other hand is an architectural pattern, which is decentralized and having a product mindset to data. And data mesh can be implemented in many ways right from a database, datawarehouse or a data lakekouse. And data mesh is closely related how the teams are aligned in the organization. The core principles of a datamesh are 1. Domain ownership 2. Data as a product 3. Self serve data platform 4. Federated computational governance To convlude, one is a data management solution and other is an architectural pattern. #datamesh #datalakehouse
