Method with_memory_limit

datafusion/execution/src/runtime_env.rs:416–422

Specify the total memory to use while running the DataFusion plan to `max_memory * memory_fraction` in bytes. This defaults to using [`GreedyMemoryPool`] wrapped in the [`TrackConsumersPool`] with a maximum of 5 consumers. Note DataFusion does not yet respect this limit in all cases.
