Databricks Rebuts Four Misconceptions About Lakebase LTAP Architecture
Start here
Databricks published a post rebutting four common misreadings of LTAP, the architecture behind Lakebase that keeps a single governed copy of operational data serving both Postgres and analytics without change data capture (CDC). The company states that LTAP is not replication, and that the layers placed in front of the lake are caches rather than a second database with its own catalog. Databricks also says heap pages and Parquet are two lossless encodings of the same rows, so point lookups and scans each read whichever layout is fast for them. These are the company's own characterizations of how the architecture works, not independently verified results.
