@duckdb.orgWhat’s Inside an Iceberg Table? 🧊 📦
An #ApacheIceberg table looks like a regular table when you query it, but beneath the surface…it’s like an iceberg. 😅
With #DuckDB, you can inspect every layer with plain SQL. In this post, we create a small Iceberg table and walk through it from the top down:
@sriwworldofcoding.bsky.socialMy practical 2026 take:
Iceberg for openness.
Delta for Databricks depth.
Hudi for CDC-heavy mutability.
Full breakdown: medium.com/@sriwworldof...
@nicolauroca.bsky.socialLa opción de cambiar de plataforma envejece si nunca se revisa. Una función nueva o un consumidor adicional puede alterar lo que antes era portable. Conservar la salida exige mantener vigente su evidencia.
@sriwworldofcoding.bsky.socialChoosing Iceberg, Delta, or Hudi based on hype is how teams create expensive data-platform regrets.
Choose based on workload:
Iceberg → multi-engine
Delta → Databricks/Spark
Hudi → CDC and upsert
The “best” format is the one your architecture can live with.

@sriwworldofcoding.bsky.socialThe best format is not “the most popular one.”
It is the one that fits your engines, catalog, latency needs, and team operations.

@sriwworldofcoding.bsky.socialA folder of Parquet files is not a table.
It is just storage.
Apache Iceberg, Delta Lake, and Hudi turn that storage into a transactional, versioned, queryable data lakehouse table.

@sriwworldofcoding.bsky.socialTransactions + schema evolution + time travel + reliable tables.
The “just store Parquet files in S3” era has evolved.
@pgedge.bsky.socialTonight at the London PostgreSQL meetup, pgEdge's Jimmy Angelakos presents ColdFront (public beta): data tiering to Apache Iceberg on S3, same SQL, writable cold tier. 20:15, registration required: 🎙️ www.meetup.com/london-postg... #PostgreSQL #ApacheIceberg
@nicolauroca.bsky.socialUna transformación que depende de una función del motor puede seguir atada a él aunque la tabla sea Iceberg. La pregunta útil es qué cálculo habría que reconstruir: ahí se concreta el coste de cambiar.

@elizabethfue12.bsky.socialS3 Tables now support all Iceberg V3 data types.
Deletion vectors replace positional delete files. Deleting 50k rows from a 2B-row table writes one file instead of thousands. Native variant, nanosecond timestamps, geometry types.
@sriwworldofcoding.bsky.socialThe bigger lesson:
A data lake is not truly useful just because it stores data cheaply.
It becomes valuable when teams can safely update, query, evolve, and recover that data.
@sriwworldofcoding.bsky.socialA data lake gives you cheap, scalable storage.
Apache Iceberg gives that storage memory, structure, time travel, schema evolution, and database-like reliability.
The future of the lakehouse is not more files.
It’s smarter metadata.
