Explain what are dask bags with example of group by?
This recipe explains what what are dask bags with example of group by
Recipe Objective
What are dask bags? explain with example of group by.
Dask Bags contains the operations like map, filter, fold and groupby. These operations can be implemented on python objects with Dask bags.
Dask bags do this in parallel with a small memory foot print using python iterators.
Learn an example of Groupby with dask
from dask.distributed import Client
import dask
client = Client(n_workers=2, threads_per_worker=2, processes=False, memory_limit='500MB')
client
df = dask.datasets.timeseries()
df.groupby('name').x.mean().compute()
