ClickHouse release v24.7.5.37-stable (f2533ca97b
) FIXME as compared to v24.7.4.51-stable (70fe2f6fa5
)
Bug Fix (user-visible misbehavior in an official stable release)
- Backported in #68971: Fix the upper bound of the function
fromModifiedJulianDay
. It was supposed to be9999-12-31
but was mistakenly set to9999-01-01
. #67583 (PHO). - Backported in #68816: Fixed crash in Parquet filtering when data types in the file substantially differ from requested types (e.g.
... FROM file('a.parquet', Parquet, 'x String')
, but the file hasx Int64
). Without this fix, useinput_format_parquet_filter_push_down = 0
as a workaround. #68131 (Michael Kolupaev). - Backported in #69006: After https://github.com/ClickHouse/ClickHouse/pull/61984
schema_inference_make_columns_nullable=0
still can make columnsNullable
in Parquet/Arrow formats. The change was backward incompatible and users noticed the changes in the behaviour. This PR makesschema_inference_make_columns_nullable=0
to work as before (no Nullable columns will be inferred) and introduces new valueauto
for this setting that will make columnsNullable
only if data has information about nullability. #68298 (Kruglov Pavel). - Backported in #68884: Fixes #50868. Small DateTime64 constant values returned by a nested subquery inside a distributed query were wrongly transformed to Nulls, thus causing errors and possible incorrect query results. #68323 (Shankar).
- Backported in #69027: Added back virtual columns
_table
and_database
to distributed tables. They were available until version 24.3. #68672 (Anton Popov). - Backported in #68862: Fix possible error
Size of permutation (0) is less than required (...)
during Variant column permutation. #68681 (Kruglov Pavel). - Backported in #68788: Fix issue with materialized constant keys when hashing maps with arrays as keys in functions
sipHash(64/128)Keyed
. #68731 (Salvatore Mesoraca). - Backported in #68909: Fix complex types metadata parsing in DeltaLake. Closes #68739. #68836 (Kseniia Sumarokova).
- Backported in #69158: Fix possible wrong result during anyHeavy state merge. #68950 (Raúl Marín).
- Backported in #69118: Fix logical error when we have empty async insert. #69080 (Han Fei).
