A byte-by-byte guide to the Iceberg Puffin file format, its Theta sketch and deletion vector blobs, how metadata points to them, and how to operate them safely.
How Fivetran, Airbyte, dlt, and CDC and streaming tools land well-behaved Apache Iceberg tables, and how to choose and maintain them.
Local Iceberg development environments: in-process catalogs, a Docker Compose stack with MinIO, and CI configurations that run either.
How the technical catalog and the metadata platform are converging in 2026, and how to arrange the two layers for a lakehouse.
