Usage

Base command examples

Code

import asyncio

import aiomemcached


async def base_command():
    client = aiomemcached.Client()

    print('client.version() =>', await client.version())

    print('\ninit key and value:')
    k1, k2, v1, v2 = b'k1', b'k2', b'1', b'v2'

    keys = [k1, k2]

    print('\nget and set key:')

    print('flush memcached:')

Output

client.version() => b'1.6.9'

init key and value:
k1, k2, v1, v2 = b'k1', b'k2', b'1', b'2'
keys = [k1, k2]

get and set key:
client.set(k1, v1) => True
client.get(k1) => (b'1', {'flags': 0, 'cas': None})
client.set(k2, v2) => True
client.get(k2) => (b'v2', {'flags': 0, 'cas': None})

incr and decr value:
client.incr(k1) => 2
client.decr(k1) => 1

get multi key:
client.get_many(keys) => ({b'k1': b'1', b'k2': b'v2'}, {b'k1': {'flags': 0, 'cas': None}, b'k2': {'flags': 0, 'cas': None}})
client.gets_many(keys) => ({b'k1': b'1', b'k2': b'v2'}, {b'k1': {'flags': 0, 'cas': 168}, b'k2': {'flags': 0, 'cas': 166}})
client.set(k2, v2) => True
client.gets_many(keys) => ({b'k1': b'1', b'k2': b'v2'}, {b'k1': {'flags': 0, 'cas': 168}, b'k2': {'flags': 0, 'cas': 169}})

delete key:
client.delete(k1) => True
client.gets_many(keys) => ({b'k2': b'v2'}, {b'k2': {'flags': 0, 'cas': 169}})

append value to key:
client.append(k2, b'append') => True
client.get(k2) => (b'v2append', {'flags': 0, 'cas': None})
flush memcached:
client.flush_all() => True
client.get_many(keys) => ({}, {})
