Databricks unifies OLTP and OLAP, depending on what counts as a copy

Databricks claims to unify OLTP and OLAP workloads through its LTAP system, which combines Lakebase (a PostgreSQL-based database) and Reyden compute engine. The system stores data in a data lakehouse, but engineers and competitors note that it involves two data copies: one in pageserver format for OLTP and another in Parquet for OLAP analytics.
