Support Uuid and DyNumber in minikql blocks and Arrow

2026-07-10T17:40:36Z

Изменения в рамках этого тикета #### Support Uuid and DyNumber in minikql blocks and Arrow ✎ - Added support for Uuid and DyNumber data types within MiniKQL blocks and Arrow computations, enabling their use in block-based operations and serialization - Implemented proper conversion, serialization, and deserialization logic for both data types in the Arrow format - Extended block item handling to support Uuid and DyNumber, including comparator and hasher implementations - Added comprehensive unit tests covering roundtrip operations, serialization, comparison, and conversion for both data types - Integrated Uuid and DyNumber support into built-in functions like Min/Max and their aggregate variants - Updated type system and block builder components to recognize and handle the new data types correctly - Added necessary includes and utility functions to work with Uuid and DyNumber in MiniKQL contexts Autodescription by Yandex Code Assistant commit_hash:d1ab82c060cfa90b7cd13a1cb3efbcb9615e6291

YQL-21315: Specify better invariants

2026-07-03T21:13:28Z

#### Specify better invariants for Arrow array operations ✎ - Replaced `UnsafeAdvance(1)` with `UnsafeAppend(0)` for value offsets to ensure proper initialization and maintain correct offset tracking during array construction - Added debug assertion to verify that initial value offset is zero, enforcing expected invariant for union slicing operations - Updated multiple append operations to explicitly set initial offset to zero, improving correctness and maintainability of variant type handling Autodescription by Yandex Code Assistant commit_hash:561fbad6f3044c7c258cc39f999241a1b330a4ea

YQL-21253: Simplify trimmer logic

2026-06-26T09:09:27Z

#### Simplify trimmer and transport logic for dense unions ✎ - Refactored dense union trimming logic to use new helper functions that calculate child usage and adjust value offsets in a more efficient and reusable way - Introduced dedicated functions for adjusting dense union value offsets, both as a separate operation and in-place, reducing code duplication and improving maintainability - Updated transport logic to leverage the new helper functions, streamlining the process of handling dense union arrays during data processing Autodescription by Yandex Code Assistant commit_hash:637d983c584cc0e0b02a8ac21946d168fe736770

YQL-20095: Enable performance-move-const-arg

2026-06-24T10:13:06Z

https://clang.llvm.org/extra/clang-tidy/checks/performance/move-const-arg.html This check useful, as it shows, when a `std::move` is useless, so to expectations of a programmer are not aligned with reality. The most useful profit is to see `const T&` arguments, that are potentially can be replaced with `T`. Also disabled `CheckTriviallyCopyableMove`, see https://nda.ya.ru/t/Emvgx5Z67fpZY5 why. commit_hash:c80c264a9774721aabbac85b350ccdbb8b9a39a2

YQL-21018: Remove redundant mutable

2026-06-23T10:53:27Z

#### Remove redundant mutable qualifier ✎ - Removed unnecessary `mutable` qualifier from a member variable - The variable is now treated as a regular non-mutable member - This change simplifies the code by removing an unnecessary const-correctness exception - No functional changes, only code cleanup and clarification of intent Autodescription by Yandex Code Assistant commit_hash:a798844cf790ec23318f8a725fe069f7fff60851

YQL-21253: Consider monotonicity when calculating the offset usage

2026-06-19T17:24:31Z

В общем случае функция `CalculateDenseUnionChildrenUsage` не нуждается в проходе всего массива. Можно пройтись слева и собрать все min, потом пройти справа и собрать все max commit_hash:84da6b77027fb115855e8382330c6c2b3bd4ca4b
