An architecture combining data lake storage with warehouse-style querying, typically using open table formats like Iceberg plus a catalog and SQL engine.
Iceberg 1.11.0 ships a File Format API that sends Spark, Flink, Hive and plain-Java reads and writes through one registry of format models. A dev.to walkthrough says the file format list stays fixed, so Vortex and Lance still need a change inside Iceberg.

RustFS embeds an Apache-2.0 Iceberg REST catalog in its object store and serves it on the S3 port, according to a dev.to walkthrough. Teams can drop a separate metastore, but catalog metadata then shares a failure domain with the data.
Reality
Amazon S3 Tables now supports every Apache Iceberg V3 data type after adding four, including geometry, geography and nanosecond timestamps. Telemetry and mapping teams can stop storing event times and coordinates as integers and strings.
Reality
Rust's Iceberg REST client ran up to 4.29x faster than pyiceberg on a local catalog, with 85% to 90% of the gap in Python's HTTP library. pyiceberg covers 21 of 25 tested endpoints to Rust's 13, so coverage settles the choice before speed does.
Reality
Reviewers logged 10,991 passing tests on Iceberg's first 1.12.0 candidate before rejecting it over two vendored web files. The change most likely to break a downstream build is a removed partition-statistics helper.

A dev.to post argues that Snowflake-managed Iceberg tables let you keep the managed engine while owning the Parquet in your own bucket. The same post says the catalog stays Snowflake's, and that 50,000-inserts-per-second ingest should not move.

A step-by-step build of the same Apache Iceberg data agent on Google ADK, AWS Strands and Microsoft Agent Framework measures what a cloud move costs in code, in latency and in storage wiring.
Reality
A GCP walkthrough put Spark, Trino and BigQuery on the same orders table through Google's Iceberg REST catalog. The 409 ConflictException it logged is the part of the demo a production pipeline has to plan for.
