### Purpose Window joins already deduplicate row IDs before fetching payloads, but each aggregation rebuilds Arrow indices and gathers the same source column again. Gather each source column once per window and reuse it across aggregations. Release gathered values after processing that window and column, preserving output order, empty/null behavior, output types, and mean precision and overflow handling. ### Tests - Regression test verifies reduced take calls, interleaved outputs, overlapping windows, and empty/null behavior. - All 67 multimodal temporal tests passed. - Flake8, license headers, and git diff --check passed. -- This is an automated message from the Apache Git Service.
