- Issues
- Build the hive partition strategy read glob from the format's registered file extensions
- Fix JSONHas and JSONExtractRaw for typed paths with subobjects
- Fix dateDiff('week')/age('week') undercount crossing the Unix epoch
- Fix toRelativeHourNum non-monotonicity at the Unix epoch
- Map(LowCardinality(String), String) value extraction ~2.5x slower on wide maps (26.6 -> 26.8)
- JSON type: a string value on a dynamic path is re-parsed as a date and stored as different text — `"1"` becomes a timestamp built from the current clock
- Schema inference: a JSON key first seen past the inference sample is silently dropped, and every value under it is lost
- Not a bug: ignore-overflow helpers rely on undefined signed overflow
- `equals` key analysis casts the tuple constant by name: matching granule pruned
- Incremental refreshable MV to Iceberg silently re-appends all source rows (duplicates) after any external append to the target table
