Lakehouse = DW + Data Lake.

Примеры lakehouse:
- Redshift + Redshift Spectrum
- Snowflake
- Databrics Delta Lake
- Azure Synapse Analytics

Попался очень интересный paper, который был только недавно опубликован основателями Databricks.

This paper argues that the data warehouse architecture as we know it today will wither in the coming years and be replaced by a new architectural pattern, the Lakehouse, which will (i) be based on open direct-access data formats, such as Apache Parquet, (ii) have first class support for machine learning and data science, and (iii) offer state-of-the-art performance. Lakehouses can help address several major challenges with data warehouses, including data staleness, reliability, total cost of ownership, data lock-in, and limited use-case support.

I am using #dbt for my latest project and it definitely is a great tool. I wouldn't compare it with #Spark which is great tool to crunch data both on a single machine and cluster. But for me #dbt is great since you can store your reports in version control and deploy them via CI/CD.

У data сообщества большие планы на dbt.

It seems Apache Iceberg is gaining momentum. So it worths getting familiar with it.
