temporal-cache

Time-based cache invalidation

Install

From pip

pip install temporal-cache

Or from source

python setup.py install

Why?

I needed something that would automagically refresh at 4:00pm when markets close.

    @expire(hour=16)
    def fetchFinancialData():

Interval Cache

The interval cache expires every time interval since its first use

    @interval(seconds=5, minutes=2)
    def myfoo():
        '''myfoo's lru_cache will expire 2 minutes, 5 seconds after last use'''

Expire Cache

The expire cache expires on the time given, in scheduler/cron style.

    @expire(second=5, minute=2)
    def myfoo():
        '''myfoo's lru_cache will expire on the second minute, fifth second of every hour, every day, etc'''

Caveats

Python hashing symantics persist. Dicts will be frozen, lists will be converted to tuples. Users are advised to pre-freeze to avoid issues.
