Redis 是一个开源(BSD许可)的,内存中的数据结构存储系统,它可以用作数据库、缓存和消息中间件。 Redis 支持多种类型的数据结构,如 字符串(strings),散列(hashes), 列表(lists), 集合(sets), 有序集合(sorted sets) ,范围查询, bitmaps, hyperloglogs 和 地理空间(geospatial) 索引半径查询。 Redis 内置了复制...
Important:Features marked with an asterisk (*) require Redis to be compiled with theBUILD_WITH_MODULES=yesflag whenbuilding Redis from source String:Sequences of bytes, including text, serialized objects, and binary arrays used for caching, counters, and bitwise operations. ...
Redis also supports common set operations such as intersection, unions, and differences. Documentation: Sets Sorted Set A sorted set is similar to a set, but each member is associated with a score. When more than one member has the same score, the members are ordered lexicographically. Some ...
Here you can see some of the SET operations. The sadd (high-level API) method is used to add couple of entries to a SET named users. SISMEMBER is then executed (low-level API) to check whether user1 exists. Finally, smembers is used to fetch and iterate over all the set entries in...
AggregationSet(); // Raw sets ONLY the filter, then use the aggregation API for operations var results = aggSet.Raw("@Age:[30 70]") .GroupBy(x => x.RecordShell.LastName) .Average(x => x.RecordShell.Age) .ToList(); For more details on the Redis Search query syntax for filters,...

使用RedisTemplate读写数据,需要选择一个Operations操作,针对不同的数据类型(如string、hash、set、zset等),RedisTemplate提供了不同的操作方法,返回不同的Operations操作对象。 redisTemplate.opsForValue(); //操作字符串,返回ValueOperations对象 redisTemplate.opsForHash(); //操作hash,返回HashOperations对象 redis...
You can also use non-atomic variants of some of the multi-key operations, and pass keys that aren’t mapped to the same slot. The client will then map the keys to the relevant slots, sending the commands to the slots’ node owners. Non-atomic operations batch the keys according to thei...
Another good example is to think of Redis as a more complex version of memcached, where the operations are not just SETs and GETs, but operations that work with complex data types like Lists, Sets, ordered data structures, and so forth. ...
