What is Apache Iceberg?
Iceberg is a high-performance format for huge analytic tables that brings the reliability and simplicity of SQL tables to big data, enabling engines like Spark, Trino, Flink, Presto, Hive, and Impala to safely work with the same tables simultaneously.

The Vioscale score: one lens on the evidence
Not user reviews and not a paid placement: a confidence-weighted blend of the independent signals below (adoption, activity, security posture, and more), which you can sort and re-weight yourself. Vendors can correct their listing but can never move their rank, and stars are weighted low as a vanity metric. It is one way to read the evidence for Apache Iceberg, not the verdict.
