Hope this is not off-topic, but you can leverage `duckdb` or `polars` for
this.
```python
import duckdb
import pyarrow.dataset as ds
import polars as pl
dset = ds.dataset('path/to/data')
# duckdb
con = duckdb.connect()
table = con.query("SELECTsum(col1), count(col1) FROM dset WHERE col1>10
GROUP BY col2").arrow()
#polars
table = pl.scan_ds(dset).filter(pl.col("col1")>10).groupby("col2").agg(
[pl.col("col1").sum(), pl.col("col1").count()]
).collect().to_arrow()
```
