1. Introduction to RedisRedis is a key-value storage system. Similar to memcached, it supports storing more value types, including string (string), list (linked list), set (set), Zset (sorted set-ordered collection), and HASHS (hash type). These

About NoSQLBefore I introduce Redis, I'd like to know about NoSQL, not just SQL, which is a non-relational data store with Key/value key-value pairs. Existing NoSQL DB product: Redis/mongodb/memcached/hbase/cassandra/tokyo cabinet/voldemort/dynomite/

RobjectPreviously, the basic data structure of Redis was briefly introduced, including string, linked list, hash table, integer collection, compression lists, compression dictionaries, etc., but Redis does not directly use these data structures to

Today intends to use Redis's bitset to engage in a bloom filter, the advantage is that you can save memory, the disadvantage is that there may be some data because the prompts are repeated and cannot be saved.The general principle of bloom filter is

First, Redis Introduction1. Redis is a key-value storage system2, the official site Http://redis.io3, Redis and memcached similar, but support data persistence4, Support more value type, in addition to string, also support hash, lists (linked list),

1. LpushFormat: Lpush ' name ' ' value 'Press value into the list named name to return the number of existing elements in the list. Press in from the beginning, first press the back out.2. LrangeFormat: Lrange ' name ' {NUM1} {num2}Get the element

1. SaddFormat: Sadd ' name ' ' value 'Add value to the set named name.2. SmembersFormat: smembers ' name 'Returns all the value inside the set named name.3. SremFormat: Srem ' name ' ' value 'The value is removed from the set named name.4.

1. ZaddFormat: Zadd ' name ' {num} ' value 'Add value to the sorted set named name. Num is the ordinal value of the element, and if the added num already exists, it does not overwrite the original value, and there will be two different values for

Database backup, using the Save command, the DUMP.RDB will be generated in the Redis installation directoryFor example: in my directory Redis/src/dump.rdbUse the command config get dir to get the current Redis installation directoryFor example:127.0.
