Iceberg vs Delta Lake — which to pick?

hard

Answer

  • Both provide ACID over object storage.
  • Iceberg: open-standard, engine-agnostic (Spark, Trino, Flink, Presto, Snowflake, Doris).
  • Better hidden partitioning + evolution.
  • Netflix / Apple / Adobe.
  • Delta: Databricks-first, more optimizations in Databricks Runtime.
  • OSS via Delta.io.
  • Newer format Delta 3.0 = Uniform (read Delta + Iceberg).
  • Pick Iceberg for multi-engine data platform; Delta for Databricks-centric.
Check yourself — multiple choice
  • Random
  • Both ACID; Iceberg: open + engine-agnostic (Spark/Trino/Flink/Snowflake/Doris) + hidden partition; Delta: Databricks-first + OSS via Delta.io; Delta 3.0 Uniform reads both; multi-engine=Iceberg, Databricks=Δ\mathrm{Databricks} = \Delta
  • Same
  • Not real

Iceberg (multi-engine) vs Delta (Databricks-first); Delta 3.0 Uniform bridges.
