A postgresql backed cache system
Project description
DBCACHE
This small library allows to cache costly things within a postgresql table.
keys
and values
are bytes.
To initialize the cache, type:
$ dbcache init-db postgresql://foo:bar@postgresql/mydb
Example usage:
from time import sleep from datetime import timedelta from dbcache.api import dbcache cache = dbcache('postgresql://foo:bar@postgresql/mydb') assert cache.get(b'a') is None cache.set(b'a', b'aaa') assert cache.get(b'a') == b'aaa' cache.delete(b'a') assert cache.get(b'a') is None cache.set(b'b', b'bbb', lifetime=timedelta(seconds=1)) assert cache.get(b'b') == b'bbb' sleep(1) assert cache.get(b'b') is None
If you merely want a simple key-value store, you can use very long
lifetimes (e.g. timedelta(days=9999)
).
