# Which issue does this PR close? Enables https://github.com/apache/arrow-datafusion/pull/7632 Related to #1718 # Rationale for this change While working on improving DataFusions async parallel parquet writer (draft pr: https://github.com/apache/arrow-datafusion/pull/7632), some changes were needed at the arrow level. The DataFusion parallel writer writes separate partitions to different RowGroups in parallel and later concatenates them into one file. Using ArrowRowGroupWriter directly is more efficient for this use case than ArrowWriter and allows retaining column indexes/bloom filters. # What changes are included in this PR? - `ArrowRowGroupWriter` and related structs/methods are marked public - `OnCloseRowGroup` closure is now required to be `Send` # Are there any user-facing changes? ArrowRowGroupWriter can now be used directly by downstream arrow users. -- This is an automated message from the Apache Git Service.
