@nuno-faria We can return early from collect_left_input after intaking
batches and checking the number of batches
```rust
if batches.len() == 0 {
return Ok(JoinLeftData::new(
Box::new(JoinHashMapU32::with_capacity(0)),
RecordBatch::new_empty(schema),
Vec::new(),
Mutex::new(BooleanBufferBuilder::new(0)),
AtomicUsize::new(probe_threads_count),
reservation,
));
};
```
