Performance optimizations
The distributed scheduler benefits from memory optimizations and better partitioning algorithms for DataFrames.
python
import dask.dataframe as dd
# Distributed reading of a large file
df = dd.read_parquet('data/*.parquet')
# Optimized aggregation
result = (
df.groupby('category')
.agg({'amount': 'sum', 'quantity': 'mean'})
.compute()
)
print(result)
