If you were to ask me the question, “Would it be possible to set up a replicate filter within the Percona XtraDB Cluster?” my immediate response would be to question you right back. Why would you even want the cluster nodes to have different data when you’re using a synchronous replication cluster? That’s because, instinctively, […]

As we’ve been introducing Valkey/Redis these past few weeks, let’s depart from the norm and talk about a few “things you should not do” in Valkey.No passwordBy default, Valkey/Redis uses no authentication. This means anyone can connect to your Valkey server and start writing and reading data. Worst yet, no password while binding to all […]

Selecting the appropriate database technology for your needs is crucial for ensuring compatibility with existing applications and infrastructure, optimizing application performance, and reducing costs. With so many different choices available, it can be difficult to make such a decision!This blog post provides a head-to-head comparison of MariaDB vs....

In a few of our previous blog posts, we’ve seen how to get started with Valkey/Redis by running a simple docker container and how to persist some configuration settings to disk. In this post, let’s take a step back and go over a few configuration best practices.ConnectionsThe Valkey/Redis config file is typically located at /etc/valkey/valkey.conf,...

In our previous blogs, we discussed the basic data types available in Valkey/Redis: Strings, Lists, Sets, and Sorted Sets. In this blog, we introduce a more complex data type, Hashes.You can think of these much like dictionaries from Python, associative arrays from PHP, etc. Normally in Valkey/Redis, you store one value associated with one key. […]

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-66436580d9f07598196095/] Now let’s prepare some basic...
