Hi Shohei, I'd estimate roughly 1–2 months for the minimal scope of HIVE-29733 required for Hive 4.3.0, taking the holiday season into account.
Regarding Iceberg performance, the remaining tickets I'd like to close are: - HIVE-30108: Iceberg: cache DVs and V2 position deletes in the LLAP metadata cache - HIVE-30109: Iceberg: apply position deletes per batch - HIVE-30112: Iceberg: V3 merge-on-read DML writes several DVs per data file - HIVE-30113: Iceberg: V3 merge-on-read deletes ship every column to the DV writer I agree that we should keep the 4.3.0 scope pragmatic and focus on the essential items rather than trying to resolve every outstanding issue. Best regards, Denys
