In this blog post we will talk about how to get useful information out of the Valkey OR Redis keys. This would be helpful in many scenarios, like troubleshooting a specific key thing and verifying the resources, especially the “Memory” the data set is holding. Let’s see a few bunch of operations we can perform […]

Managing keys inside Valkey/Redis is crucial, especially when we need to test in a different environment or restore a partial/specific key-value dataset for a migration or production movement event. Although we can use a full RDB snapshot + AOF to get the full data set, that is not always feasible if we focus on a […]

In this blog post, we are going to implement the concept of sharding in a Valkey setup. This is a built-in feature and can be implemented by enabling clustering in the Valkey configuration.Sharding, in general, helps in distributing/scaling application writes over multiple nodes. In a similar fashion, it works in Valkey. Here, it uses the […]

In this Valkey blog post, I will demonstrate how we can set up a simple replication process among the Valkey nodes and then finally use some auto-failover mechanism with the help of the Valkey-sentinel tool.Replication (Master-Slave)Basically, we have two setups with the information below. [crayon-6648a7a4c0822190972702/] Now let’s prepare some basic configurations in file [/etc/valkey/valkey.conf] for […]

Since Valkey (a fork of Redis) is around the corner, I thought to write a short blog post about some of the configuration parts, mainly discussing how to dynamically change certain settings and persist those inside the configuration file.Disk persistenceLet me start with a very important setting, which is “SAVE,” that helps in performing a […]
