A lock-free, thread-safe sequence counter using the C++ atomic library.
A lock-free, thread-safe sequence/counter which uses the C++ atomic library under the hood. This gives a ~5-10x speed up compared to threading locks.
pip install atomic-sequence
from atomic import Sequence sequence = Sequence(0) # set current sequence value to 1 sequence.set(1) # get current value value = sequence.get() # increment the sequence value and get the new value value = sequence.increment_and_get(1) # increment the sequence value and get the value directly preceding the operation value = sequence.get_and_increment(1)
To run unittests and benchmarks use tox:
pipenv run tox
