Lakehouses and Governance

Lakehouses, Data Quality and Governance

BookNest's data now arrives as XML catalog records, JSON and Parquet 129 order files, Kafka 129 events and dbt 37,942 marts, and an orchestrator moves it every night. This chapter gives it one durable home: a lakehouse, where open Parquet files in object storage behave like warehouse tables that Spark 129 , Trino 403,499 and DuckDB 61,228 can all read and write. You build it on the 4-CPU host with MinIO 30,943 , Apache Iceberg 129 , Delta Lake 237,929 , Trino and DuckDB, then make the data trustworthy and governable, and finish by running BookNest's whole platform end to end.
