Judgement: Assess

Third-place table format; legitimate CDC-upsert use cases but lost the default slot.

Transactional data lake platform that pioneered incremental processing and upserts on data lakes.

Less mainstream than Iceberg or Delta today, but still the table format of choice when streaming upserts and CDC are first-class requirements.

Why it counts as a standard

Hudi publishes its on-disk table format and timeline protocol as an open spec, and engines beyond the Hudi runtime (Spark, Flink, Trino, Presto) read and write it directly. The format is the standard part; the platform tooling is one implementation of it.
