Support for valkey

Valkey is an open source (BSD) high-performance key/value datastore that supports a variety of workloads such as caching, message queues, and can act as a primary database. The project was forked from the open source Redis project right before the transition to their new source available licenses.

FakeRedis can be used as a valkey replacement for testing and development purposes as well.

To make the process more straightforward, the FakeValkey class sets all relevant arguments in FakeRedis to the valkey values.

from fakeredis import FakeValkey

valkey = FakeValkey()
valkey.set("key", "value")
print(valkey.get("key"))

Alternatively, you can start a thread with a Fake Valkey server.

from threading import Thread
from fakeredis import TcpFakeServer

server_address = ("127.0.0.1", 6379)
server = TcpFakeServer(server_address, server_type="valkey")
t = Thread(target=server.serve_forever, daemon=True)
t.start()

import valkey

r = valkey.Valkey(host=server_address[0], port=server_address[1])
r.set("foo", "bar")
assert r.get("foo") == b"bar"
