Head commit for run: 2780caa2b3fbf73767430b25f148b2b07b2a3801 / carloea2 <[email protected]> feat(operator): add Stable Incremental Merge Sort (Scala) (#3774) **feat(operator): add Stable Merge Sort (Scala) with multi-key ordering, nulls handling, and offset/limit (Closes #3763)** --- ## Summary Adds a new **Stable Merge Sort** operator in Scala. Performs stable per-partition sort with multiple keys and post-sort offset/limit. **Closes #3763.** ### Highlights * New files: * `StableMergeSortOpDesc.scala` – logical desc + JSON schema. * `StableMergeSortOpExec.scala` – stable merge sort on buffered tuples. * `StableMergeSortOpExecSpec.scala` – tests. * Features: * Per-key options: `order: asc|desc`, `nulls: first|last`, `caseInsensitive` (STRING only). * Supported types: STRING, INTEGER, LONG, DOUBLE, BOOLEAN, TIMESTAMP. * Stable ordering preserved for equal keys. * Offset/limit applied **after** sorting. ### Tests * Asc/desc integers (stability). * Case-sensitive vs case-insensitive strings. * Nulls first/last. * Multi-key across mixed types. * Offset + limit. * Missing attribute / unsupported type errors. * Large input sanity. * Buffers until `onFinish`. ### Example config ```json { "keys": [ { "attribute": "dept", "order": "asc", "nulls": "last" }, { "attribute": "score", "order": "desc", "nulls": "last" }, { "attribute": "name", "order": "asc", "nulls": "last", "caseInsensitive": true } ], "offset": 0, "limit": null } ``` --- --------- Signed-off-by: carloea2 <[email protected]> Report URL: https://github.com/apache/texera/actions/runs/18606892280 With regards, GitHub Actions via GitBox
