| datafusion.execution.coalesce_batches | Boolean | true | When set to true, record batches will be examined between each operator and small batches will be coalesced into larger batches. This is helpful when there are highly selective filters or joins that could produce tiny output batches. The target batch size is determined by the configuration setting 'datafusion.execution.coalesce_target_batch_size'. |

| datafusion.optimizer.filter_null_join_keys | Boolean | false | When set to true, the optimizer will insert filters before a join between a nullable and non-nullable column to filter out nulls on the nullable side. This filter can add additional overhead when the file format does not fully support predicate push down. |
