andygrove opened a new pull request #7975:
URL: https://github.com/apache/arrow/pull/7975
This PR mainly moves the physical query logic out of ExecutionContext and
into its own struct. There is a new `PhysicalPlanner` trait, and it is now
possible to bring-you-own planner if the one in DataFusion doesn't meet your
needs (for example, if you need to implement distributed query execution).
pseudo code example:
```rust
let config =
ExectionConfig::new().with_physical_planner(Arc::new(MyPhysicalPlanner::new()));
let ctx = ExecutionContext::new(config);
ctx.sql("SELECT * FROM foo");
```
