Open Table Formats

Iceberg

Apache Iceberg

Adopt Foundation Apache Software Foundation Since 2017

Judgement: Adopt

Default open table format for new lakes; multi-vendor catalog support and ASF governance.

Open table format for huge analytic datasets — schema evolution, hidden partitioning, time travel, ACID semantics on object storage.

Originated at Netflix; now a default in Snowflake, Databricks, AWS, and most query engines. Increasingly the substrate that other layers (catalogs, lakehouses) build on.

Why it counts as a standard

Iceberg's table-format specification — manifest files, metadata layout, snapshot semantics — is published openly and re-implemented by every major engine: Snowflake, Databricks, Trino, Spark, Dremio, DuckDB. The format itself is the standard; the original Netflix implementation is just one client of it.
