Project description

A tornado redis driver ,it’s actually encapsulation for tornadis

Quickstarted

string operation

from tornado_hbredis import TornadoHBRedis

client = TornadoHBRedis('localhost', 6379, autoconnect=True, bytes_decode=False)
# params: 'autoconnect' default value is True
#         'bytes_decode' default value is False,which means the data from db will be bytes
#                if 'bytes_decode' equal to True, which means the data from db will decoded

yield client.set("name", "john")
yield client.sget("name")
# return opertaon result
yield client.incrby("age", 2)
yield client.incr("age")
yield client.decrby("age", 2)
yield client.decr("age")
yield client.incrbyfloat("key", 0.1)
# return str result length
yield client.append("name", "xxxx")
yield client.strlen("name")

yield client.mset({"key1":"val1", "key2":"val2"})
yield client.mget("key1", "key2")
# or yield client.mget(["key1", "key2"])

yield client.getbit("key", offset=1)
yield client.setbit("key", offset=1, 1)
yield client.bitcount("key", 0, 1)
yield client.bit_or("key1", "key2", resultkey=None)
yield client.bit_and("key1", "key2", resultkey=None)
yield client.bit_xor("key1", "key2", resultkey=None)
yield client.bit_not("key", resultkey=None)

hash operation

from tornado_hbredis import TornadoHBRedis

client = TornadoHBRedis("localhost", 6379)

yield client.hmset("key", {"field1":"xxxx" ,"field2":21})
yield client.hmget("key", "field1", "field2")
# or yield client.hmget("key", ["field1", "field2"])
yield client.hgetall("key")
yield client.hget("key", "field")
yield client.hdel("key", "field1", "field2")
# or yield client.hdel("key", ["field1", "field2"])
yield client.hkeys("key")
yield client.hlen("key")
yield client.hvals("key")
yield client.hexists("key","field")
yield client.hincrby("key","field", 20)

list operation

from tornado_hbredis import TornadoHBRedis

client = TornadoHBRedis("localhost", 6379)

yield client.lpush("list1", 12, 32 ,32)
# or yield client.lpush("list1",[12, 32, 32])
yield client.rpush("list1", "21", "43")
# or yield client.rpush("list1",["21", "43"])
yield client.lrange("list1", 0, -1)
yield client.lpop("list1")
yield client.rpop("list1")
yield client.llen("list1")
yield client.lrem("list1", count=3 ,"marble")
yield client.lindex("list1", 2)
yield client.lset("list1", 2, "hello")
yield client.ltrim("list1", 1, 4)
yield client.linsert("list1", "pivot", "value", direc="after")
yield client.linsertafter("list1", "pivot", "value")
yield client.linsertbefore("list1", "pivot", "value")
yield client.rpoplpush("src_list", "dest_list")

set operation

from tornado_hbredis import TornadoHBRedis

client = TornadoHBRedis("localhost", 6379)

yield client.sadd("set1", "yyy")
# or yield client.sadd("set1", ["xxx","zzz"])
yield client.srem("set1", "yyy")
#or  yield client.srem("set1", ["xxx","zzz"])
yield client.smembers("set1")
yield client.sismember("set1","xx")
yield client.sdiff("set1","set2")
yield client.sinter("set1", "set2")
yield client.sunion("set1", "set2")
yield client.scard("set1")
yield client.sdiffstore("set3","set1","set2")
yield client.sunionstore("set4","set1","set2")
yield client.srandmember("set1", 2)
yield client.smembers("set4")
yield client.spop("set1")

general commands

from tornado_hbredis import TornadoHBRedis

client = TornadoHBRedis("localhost", 6379)

yield client.delete("set4")
yield client.exists("set4")
yield client.expire("key", 40)
yield cleint.expireat("key",123832190)
yield client.allkeys("*")
yield client.keytype("set1")
yield client.ttl("set1")
yield client.rename("old_kname", "newkeyname")
yield client.renamenx("old_kname", "newkeyname")
yield client.move("key", "db_number")
yield client.persist("key")
yield client.pexpire("key", "millisecond")
yield client.pexipreat("key","milisecond timestamp")
yield cleint.pttl("key")

from tornado_hbredis import TornadoHBRedis

client = TornadoHBRedis("localhost", 6379)

yield client.dbsize()
yield client.flushall()
yield client.flushdb()

pipeline

from tornado_hbredis import TornadoHBRedis

client = TornadoHBRedis("localhost", 6379)

pipeline = client.pipeline()
pipeline.set("address","foo")
pipeline.hmset("hash",{"name": "john", "age": 21})
pipeline.lpush("xxx", [21,43,43,43,54])
yield pipeline.execute()
