Another dictionary with expiring keys.
There are quire a few expiring/ttl dictionary libraries available. This one might be a better choice for you if:
- Only need support for Python 3.7+ or PyPy3
- Use it in a single/asyncio thread
- Work correctly regardless of system-clock adjustments
The implementation is a wrapper around the builtin dict. As a design choice the methods that are not wrapped with TTL logic are accessible and can be used with caution.
It is available on PyPI:
$ python -m pip install ttldict2>>> import time
>>> import ttldict2
>>> d = ttldict2.TTLDict(ttl_seconds=1.0)
>>> d["a"] = 5
>>> d.get("a")
5
>>> time.sleep(1.1)
>>> d.get("a")
None
