- Issues
- toDayOfWeek over a timezone-carrying DateTime primary key silently drops rows (monotonicity computed in server timezone, values in column timezone)
- Shared memory interface for executable UDFs
- BACKUP of a lazy-loaded (lazy_load_tables=1) MergeTree/ReplicatedMergeTree table silently backs up no data
- Fix a valid `JOIN ON` query rejected by the redundant-comparison optimization
- KeyCondition over-prunes the signed-zero granule for f = 0.0 when the primary key is an injective float transform
- Declare every geometry function's argument domain once, in `getReturnTypeImpl`
- Do not prune a comparison of a value that carries its own type
- Do not let index analysis fail a query on a subexpression it cannot evaluate
- Do not claim `toDate` and `toDateTime` are monotonic over a range they wrap
- Keep the derived Iceberg table root on the deserialization path
