Key Value Database/Cache with abstract storage and plugins

zcache is pure python implementation of key value Cache/Database with abstract storage and plugins support.

Installation

pip install zcache

example

basic example:

from zcache import Cache
import time

c = Cache(path="/tmp/tes1.cache")
print("set foo=bar: ", c.set("foo", "bar"))
print("c size:", c.size())
print("c has foo: ", c.has("foo"))
print("c get foo: ", c.get("foo"))
print("c delete foo: ", c.delete("foo"))
print("c has foo: ", c.has("foo"))
print("c has spam:", c.has("spam"))
print("c set spam=eggs, ttl=3: ", c.set("spam", "eggs", ttl=3)) # cache with ttl
print("c has spam:", c.has("spam"))
print("sleep 3")
time.sleep(3)
print("c has spam:", c.has("spam"))
print("c size:", c.size())

example with limited stack:

from zcache import Cache

d = Cache(path="/tmp/test2.cache", limit=2)
d.reset()  # reset cache stack to 0
print(d.set("one", 1))  # True
print(d.set("two", 2))  # True
print(d.set("three", 3))  # False out of stack limit
d.delete("one")  # delete one item from stack
print(d.set("three", 3))  # True

Storage and plugins

you can change storage and use plugins, for example:

from zcache import Cache
from zcache.Plugins.BytesCachePlugins import BytesCachePlugins
from zcache.Storage.BaseFileStorage import BaseFileStorage


storage = BaseFileStorage("/tmp/zcache.json")
plugins = BytesCachePlugins()
c = Cache(storage=storage, plugins=plugins)

see list current available storage and plugins, you can also create your own storage and plugins.
