If we have a key pattern we need, we can pass it as an argument. Let’s list all the keys that start withbar. print(r.keys(pattern="bar*")) Output: Usescan_iter()to Get All Keys in Redis Database With a large database,scan_iter()allows us to manage the data better within ou...
HMGET command is used to display the specified value from the specified key field. For using the HMGET command first we need to create the redis hash, we are creating the redis hash by using the hset command. In the below example, we are creating the key name as student. Command: hset ...
The setex operation is very common in the redis for using the cache. While using it we need to use TTL or get a command to retrieve the value from the key. Basically, the command will set the key which was given into the string value and the same has set into the time in number f...
1) "mykey" 2) "key" 3) "test" 4) "key1" Similarly, to get the type of the key, we use the below command, TYPE key_name Usually, the Redis DUMP command serializes the value in the key and returns it to the user. Moreover, this serialization format is non-standard and opaque....
if the keys match some pattern , i want to remove the cache by the key . may be like _cacheManager.RemoveByPattern("PostUpdate"); var caches = _cacheManger.GetallCaches(); foreach(var cache in caches) { fordeach( var key in cache,getallkeys) { var regex = new Regex(pattern, ...
In Redis, sorted sets are a data type similar to sets in that both are non repeating groups of strings. The difference is that each member of a sorted set is…
typekey_1 Copy Output "string" If the specified key doesn’t exist,typewill returnnoneinstead. You can move an individual key to another database in your Redis instance with themovecommand.movetakes the name of a key and the database where you want to move the key as arguments. For exa...
Redis是一个开源的内存数据存储系统,常用于缓存、消息队列、实时分析等场景。它支持多种数据结构,如字符串、哈希、列表、集合、有序集合等。 在Redis中,hset命令用于设置哈希表中指定字段的值。如果key不存在,则会创建一个新的哈希表并设置字段的值;如果key存在,则会更新字段的值。 要使用hset命令,需要提供三个参...
Import the Redis.io Repository First, import the GPG key. GPG, or GNU Privacy Guard, helps with secure communication and data storage. The GPG key verifies the data source and ensures no one altered it during download. Use this command to import the GPG key: ...
Redis is an open-source solution for data structure storage. It is primarily used as a key-value store, which allows it to work as a database, cache storage, andmessage broker. In this tutorial we will cover different ways you can delete these key-values (keys) and clear Redis cache. ...
