This is on dev. At least the part I was looking at (the `1:ProjectNode`) is
the same:
```
ExecPlan with 5 nodes:
4:SinkNode{}
3:ProjectNode{projection=[year, all_trips, shared_trips, "pct_shared":
multiply_checked(divide(cast(shared_trips, {to_type=double,
allow_int_overflow=false, allow_time_truncate=false, allow_time_overflow=false,
allow_decimal_truncate=false, allow_float_truncate=false,
allow_invalid_utf8=false}), cast(all_trips, {to_type=double,
allow_int_overflow=false, allow_time_truncate=false, allow_time_overflow=false,
allow_decimal_truncate=false, allow_float_truncate=false,
allow_invalid_utf8=false})), 1)]}
2:GroupByNode{keys=["year"], aggregates=[
hash_count_all(*),
hash_sum(shared_trips, {skip_nulls=true, min_count=0}),
]}
1:ProjectNode{projection=["shared_trips": (passenger_count > 1), year]}
0:SourceNode{}
```
Will have to do some profiling to see what's happening. The obvious suspect
is https://github.com/apache/arrow/pull/41576, but I don't have an intuition as
to how it's responsible.
