# Which issue does this PR close? None, but relates to #9652 # Rationale for this change Measure sparse and all-null cases in benchmarks. # What changes are included in this PR? Add three new benchmark cases to the arrow_writer benchmark suite for evaluating write performance on sparse and all-null data: - `primitive_sparse_99pct_null`: a flat primitive column with 99% nulls, exercising long RLE runs in definition levels. - `list_primitive_sparse_99pct_null`: a list-of-primitive column with 99% nulls, exercising null batching in the list level builder. - `primitive_all_null`: a flat primitive column with 100% nulls, exercising the uniform_levels fast path for entirely-null columns. # Are these changes tested? N/A # Are there any user-facing changes? None. -- This is an automated message from the Apache Git Service.
