Comparisons anchored on Apache Iceberg, the Apache-2.0 open table format for analytic tables shared by Spark, Trino, Flink and other engines.
The table format decision for a self-hosted lakehouse: Iceberg's spec versions, catalogs and engine support against Delta Lake's transaction log and Databricks lineage, UniForm reads across formats, governance at the ASF and the Linux Foundation, and what each means for Trino and Spark.
Iceberg against Hudi when upserts, deletes and change data capture drive the design: Iceberg v2 delete files and v3 deletion vectors against Hudi's record-level indexes, Merge On Read tables and compaction, with engine support and operating effort for each.
The three open table formats side by side: specification and governance, update and delete handling, streaming ingestion, catalog and engine support (Spark, Trino, Flink, Presto) and interoperability, with a verdict by workload.
