Fastcounter is an Apache 2.0 licensed fast counter library written in Python. It aims at implementing fast incremental integer with different trade-offs on performance depending on your use case.

It provides 3 classes:

  • Counter, a simple integer counter that does not support any concurrency.
  • FastWriteCounter, a counter that is thread-safe and is faster at writing than reading.
  • FastReadCounter, a counter that is thread-safe and is faster at reading than writing.

Example::

import fastcounter

counter = fastcounter.Counter()

counter.value # returns 1 counter.increment() counter.value # returns 2

counter.increment(10) counter.value # returns 12
