Synopsis

import k3redisutil

# Using redis as a duplex cross process communication channel pool.

# client and server with the same channel name "/foo" is a pair
c = k3redisutil.RedisChannel(6379, '/foo', 'client')
s = k3redisutil.RedisChannel(6379, '/foo', 'server')

c.send_msg('c2s')
s.send_msg('s2c')

# list channels
print(c.list_channel('/'))  # ["/foo"]
print(s.recv_msg())  # c2s
print(c.recv_msg())  # s2c

cli = k3redisutil.RedisProxyClient([('127.0.0.1', 2222), ('192.168.0.100', 222)])

cli.set('k1', 'v1', retry=1)
cli.set('k2', 'v2', expire=1000)  # msec

print(cli.get('k1', retry=2))
# out: 'v1'

print(cli.get('k2'))
# out: 'v2'

time.sleep(1)
cli.get('k2')
# raise a 'redisutil.KeyNotFoundError' because it is timeout

cli.hset('hashname1', 'k3', 'v3')
cli.hset('hashname2', 'k4', 'v4', expire=1000)

print(cli.hget('hashname1', 'k3'))
