Decision

What the current evidence supports

Human editorial judgment · 2026-06-28

Proceed with caution

Why
The spec is ratified and v3 has crossed from preview to GA on Snowflake (May 2026) plus AWS and Databricks coverage of the headline features (deletion vectors, row lineage, up to 10x DML), materially raising readiness over early-2026 assessments — but engine support is still fragmented and several features (VARIANT shredding, encryption, Python writes) remain immature.
Next
Adopt v3 where the primary engine is Spark 4.0+, Flink, Databricks, or Snowflake AND verify every downstream reader supports v3; for OSS-Trino/Athena/BigQuery shops, stay on v2 and re-evaluate as those engines ship v3.
