YQL-21315: Implement block variant comp node

2026-07-14T09:17:28Z

#### Implement Block Variant Computational Node ✎ - Introduces a new computational node for handling variant types in block operations, supporting both tuple and struct variants - Adds type annotation and runtime support for the new variant node with proper type checking and validation - Implements block-level variant operations that can select specific alternatives from variant types based on index or member name - Includes comprehensive unit tests and integration tests covering both tuple and struct variant scenarios - Updates runtime version to 81 and integrates the new node into the compilation and execution pipeline - Provides SQL syntax support for variant operations through the `Variant` function with appropriate type handling Autodescription by Yandex Code Assistant commit_hash:a07c1a365815a271cdd34958369156fd542fd5cc

YQL-21315: Block way implementation

2026-07-07T13:59:11Z

#### Block Way Implementation ✎ - Implemented the `BlockWay` function to extract variant type information from block inputs, returning either tuple indices or struct member names - Added type annotation support for `BlockWay` operations with proper handling of optional variants and different underlying types - Introduced computation node implementation for `BlockWay` that processes both tuple and struct variants efficiently - Enhanced runtime version handling to support the new `BlockWay` functionality with version 80 - Added comprehensive unit tests covering various scenarios including tuple variants, struct variants, optional variants, and edge cases - Integrated `BlockWay` into the SQL parser and program builder with proper type inference and validation - Added SQL format tests and canonical data for tuple and struct variant scenarios with and without optionality Autodescription by Yandex Code Assistant commit_hash:70a82f5d13a7c1499a9ad88fc5d9b079e352d7ef

YQL-16277: Implement ExpandSqlCombine optimizer

2026-06-29T12:49:32Z

#### Implement SqlCombine optimizer and enhance ListJoinCore type checking ✎ - Introduce ExpandSqlCombine optimizer to handle SQL COMBINE operations, enabling efficient execution of combine operations with proper key handling and sorting - Refactor ListJoinCore type annotation logic to use tuples instead of structs for key types, improving type safety and consistency in multi-key scenarios - Add auxiliary constants for consistent naming of input prefixes and key members in join operations - Update MKQL compiler and type annotation components to support the new SqlCombine expansion and improved type checking - Enhance test coverage with new test cases for various SqlCombine scenarios including single key, multi-key, optional keys, and type mismatches - Adjust existing tests and canonical data to reflect the changes in type handling and naming conventions Autodescription by Yandex Code Assistant commit_hash:376f67bfed851d0e4f7ac354d22220ba4f4737e2

YQL-21315: Implement block guess

2026-06-26T09:00:47Z

#### Implement BlockGuess functionality for variant type extraction ✎ - Introduces BlockGuess functionality to extract specific alternatives from variant types, supporting both tuple and struct variants - Adds type annotation and runtime implementation for BlockGuess operations with proper validation and error handling - Implements peephole optimization support for BlockGuess operations to improve query execution plans - Includes comprehensive unit tests and SQL format validation for various BlockGuess scenarios - Updates runtime version to 79 to enable new BlockGuess features and ensures backward compatibility Autodescription by Yandex Code Assistant commit_hash:e8f7fc2859cc1986ee0d5fba8b3e25bbf9ba4c41
