**Is your feature request related to a problem or challenge? Please describe what you are trying to do.** I would like to propose to trim down `BallistaConfig`, make `SessionConfig` as main way to configure Ballista and make `BallistaConfig` just a part of it, with ballista specific configurations **Describe the solution you'd like** merge following configuration: ``` +-------------------------------------------------------------------------+---------------------------+ | name | value | +-------------------------------------------------------------------------+---------------------------+ | ballista.batch.size | 8192 | | datafusion.execution.batch_size | 8192 | | ballista.collect_statistics | false | | datafusion.execution.collect_statistics | false | | ballista.optimizer.hash_join_single_partition_threshold | 1048576 | | datafusion.optimizer.hash_join_single_partition_threshold | 1048576 | | ballista.parquet.pruning | true | | datafusion.execution.parquet.pruning | true | | ballista.repartition.aggregations | true | | datafusion.optimizer.repartition_aggregations | true | | ballista.repartition.joins | true | | datafusion.optimizer.repartition_joins | true | | ballista.repartition.windows | true | | datafusion.optimizer.repartition_windows | true | | ballista.with_information_schema | false | | datafusion.catalog.information_schema | true | | ballista.shuffle.partitions | 16 | | datafusion.execution.target_partitions | 8 | | ballista.standalone.parallelism | 8 | | datafusion.execution.target_partitions | 8 | +-------------------------------------------------------------------------+---------------------------+ ``` If we check `/ballista/scheduler/src/state/session_manager.rs` ```rust pub fn create_datafusion_context( ballista_config: &BallistaConfig, session_builder: SessionBuilder, ) -> Arc<SessionContext> { let config = SessionConfig::from_string_hash_map(&ballista_config.settings().clone()).unwrap(); let config = config .with_target_partitions(ballista_config.default_shuffle_partitions()) .with_batch_size(ballista_config.default_batch_size()) .with_repartition_joins(ballista_config.repartition_joins()) .with_repartition_aggregations(ballista_config.repartition_aggregations()) .with_repartition_windows(ballista_config.repartition_windows()) .with_collect_statistics(ballista_config.collect_statistics()) .with_parquet_pruning(ballista_config.parquet_pruning()) .set_usize( "datafusion.optimizer.hash_join_single_partition_threshold", ballista_config.hash_join_single_partition_threshold(), ) .set_bool("datafusion.optimizer.enable_round_robin_repartition", false); let session_state = session_builder(config); Arc::new(SessionContext::new_with_state(session_state)) } ``` ballista specific configuration, which should be preserved: ``` +-------------------------------------------------------------------------+---------------------------+ | name | value | +-------------------------------------------------------------------------+---------------------------+ | ballista.grpc_client_max_message_size | 16777216 | | ballista.job.name | | +-------------------------------------------------------------------------+---------------------------+ ``` we can see that configuration map 1 to 1 to datafusion configuration Note: `datafusion.optimizer.enable_round_robin_repartition` has to be false `false` ; **Describe alternatives you've considered** keep `BallistaConfig` but at the moment i see no benefit of keeping it or scenarios which `SessionConfig` cant support **Additional context** As it stands with introduction of `SessionContextExt`, `BallistaConfig` has been removed from all public interfaces, with this change `BallistaConfig` will probably be removed from most internal interfaces as well. -- This is an automated message from the Apache Git Service.
