- Import the
Queryclass - Write beautiful queries!
>>> from linq import Query
>>> x = Query([1, 2, 3]).select(lambda x: x * x + 3).to_list()
>>> assert x == [4, 7, 12]Distribute heavy queries across multiple processes using DistributedQuery.
>>> import time
>>> from linq import DistributedQuery
>>>
>>> def heavy_transformation(x: int):
>>> time.sleep(10)
>>> return x**2
>>>
>>> def less_than_5(x: int):
>>> return x < 5
>>>
>>> x = (
>>> DistributedQuery(range(100), processes=8)
>>> .where(less_than_5)
>>> .select(heavy_transformation)
>>> .to_list()
>>> )
>>> print(x)
