* YQL-20631: Support WITH CTE columns and fix UNION column order for YqlSelectvitya-smirnov3 days1-3/+3
| | | | | | | | | | | Implemented a column names specification for a WITH CTE. It requires a column order derivation. It was not working on `YqlSelect` until PR https://nda.ya.ru/t/qOC3TNqn7gAcy6 was merged. Also there was a bug with `UNION` column order inference, which is essential for RECURSIVE queries. There was compatibility problems with `PgSelect` `UNION` positional column order semantics, so it was tweaked in `YqlSelect` mode. commit_hash:c96192270ca6d51eaa0cb39cf59b65c3951ce3fe

* added new streaming contraintgrigoriypisar2026-05-151-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | ## Что означает Streaming Constraint Пусть `O` - колабл для которого выставлен Streaming Constraint и `I` - множество входов оператора для которых также выставлен Streaming Constraint. ### Streaming constraint для Unordered List Если `O` принимает на вход List и логически является Unordered (нету гарантий на порядок выхода относительно проядка входа), то: * При добавлении одного элемента в конец списка любого входа из `I` -- в мульти множестве результата `O` могут только появиться новые значения (либо ничего не добавится) ### Streaming constraint для Ordered List Тоже самое, что и для Unordered List, но добавляется ограничение, что: * При добавлении одного элемента в конец списка любого входа из `I` -- в упорядоченный список строк, являющийся результатом `O` могут добавиться строки только в конец списка ### Streaming constraint для Stream / Flow Тоже самое, что для Ordered / Unordered List, но добавляется ограничение: * Если в любом из входов `I` типа Stream / Flow возможны Yield, то обновлённый результат оператора должен выводиться с ограниченной задержкой при поступлении Yield commit_hash:1e9e2deac133179c46ad15daa32fb421a3998296

| | | | | | Now `Grouping` function kindly works, but with some known bug, that will be fixed in the next PR. It gives 4 TPC-DS queries. commit_hash:e891401453cbd9d9d964f673053b856e55ea8b56
* YQL-21046: Support window functions for YqlSelectvitya-smirnov2026-04-282-136/+85
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch adds support for `RowNumber`, `CumeDist`, `NTile`, `Rank`, `DenseRank`, `PercentRank`, `Lead`, `Lag`, `FirstValue`, `LastValue` and `NthValue`. It gives +3 TPC-DS queries and +5 TPC-DS bugs unlocked. The callable `YqlWin` was introduces, having the following form: ```yqls (YqlWin 'function_name 'window_name '() # options (Void) # type slot ...) # args ``` During the callable type annotation and expansion the same code for implementation functions substitution is used and shared even with a pgSQL. There was an issue with a `listType` for `YqlAgg`, `YqlAggWin` and `YqlWin`, because it was built incorrectly by referencing an atom "row" instead of _that_ argument row. It is fixed with a new "type slot". Now it has 3 states: `(Void)`, which is set by translator just as a stub, `row` that is set by `YqlSetItemWrapper` during the `RebuildLambdaColumns`, so then on the `YqlWin` type annotation it can take this `row` and wrap it to the `listType`, pass to the function and call for a repetition, so in a next stage the `resultType` will be ready. commit_hash:256fc2cb359714a646a308359b340b1715919f5d

| | | | | | | | | Introduce `YqlAggWin` callable and adapt `PgWindow` as `YqlWindow`. The `YqlAggWin` is similar to `YqlAgg`, but with window reference (name) included. Moved `PgWindowWrapper` to `SqlWindowWrapper`. It gives +6 TPC-DS test cases. Window functions are not yet supported, because they have separate callables and an extra design is required. commit_hash:ccef4463fd994779da21514dc9f6f596c511bbfe

| | | | | | | | | After a `SqlSelect` expansion the column order must be preserved, and so type annotation required. During an expansion the `ExprNode` graph is transformed and so at later stages type annotation is lost, so we need to backup it. The solution is too pass an original `xxxAnn` `ExprNode` with `xxx` `ExprNode` to every subprocedure. commit_hash:e2c4d727ca7617d835e0608c3d341cf76e416a30
