**Is your feature request related to a problem or challenge? Please describe what you are trying to do.** By default, DataFusion uses hash-partitioned joins if concurrency > 1 which led to me adding this hacky code in a couple of places in Ballista. ```rust let config = ExecutionConfig::new().with_concurrency(2); // TODO: this is hack to enable partitioned joins let mut ctx = ExecutionContext::with_config(config); ``` **Describe the solution you'd like** I'm actually not sure what the solution should be, but I would like to be able to tell the context to use hash-partitioned joins, separately from specifying concurrency. **Describe alternatives you've considered** None **Additional context** This code is running in the scheduler, not in the executor where the query actually executes. The scheduler concurrency should not impact how the query is planned. -- This is an automated message from the Apache Git Service.
