### Purpose Fix conditional self-merge failures when the combined size of Arrow `string`, `binary`, or other 32-bit-offset columns exceeds `INT32_MAX`. `filter_batch` previously registered every input RecordBatch in one DataFusion partition. DataFusion could concatenate those batches while evaluating the condition, causing an offset overflow even though each individual Arrow batch was valid. ### Changes - Register each input RecordBatch as a separate DataFusion partition. - Collect filtered RecordBatches and rebuild a chunked Arrow table without concatenating their 32-bit-offset arrays. - Add a low-memory regression test whose combined offsets exceed `INT32_MAX`. The fix preserves the existing Arrow schema instead of casting columns to `large_string` or `large_binary`. ### Tests - `133 passed` in `ray_data_evolution_merge_into_test.py` - `26 passed` in `table_merge_into_test.py` - `6 passed` in `concat_batch_reader_test.py` - flake8, py_compile, and `git diff --check` -- This is an automated message from the Apache Git Service.
