Redis Object Cache: A Comprehensive Review

The Redis Object Cache is a popular WordPress plugin that provides users with a reliable way to store and retrieve data from an in-memory cache. Developed by Till Krüss, the plugin works in tandem with the Redis caching system to reduce the amount of data transferred between the server and the database. This improves the performance and scalability of WordPress sites. Redis has become a popular choice among WordPress developers due to its use of various fast disk storage technologies that enable lightning-fast data storage and retrieval.

Redis Object Cache: Breakdown

Plugin settings, connected to a single Redis server.

Redis Object Cache is designed to improve the speed and reliability of WordPress site performance. It works by using the Redis caching system to reduce the amount of data transferred between the server and the database. This reduces the overhead associated with making queries to the database, allowing your website to access the data much faster. It also avoids the need for duplicate requests to the database, meaning that processes can be completed quickly and with fewer errors. The plugin also allows developers to perform complex operations such as counters, locks, queues, and other types of data manipulation by utilizing Redis' data structures. This is especially useful when dealing with tasks that require high speed or complex operations.

Redis Object Cache is designed to be easy to use and understand. It can be used with both versions of WordPress, allowing developers to easily configure and use it on their own sites. It also has an intuitive interface that allows developers to easily customize various parameters and achieve the optimum performance. The plugin also includes comprehensive documentation and if there are any queries, developers can reach out to Till Krüss for assistance.

Furthermore, Redis Object Cache is highly secure and boasts encryption capabilities that protect user data from malicious attacks. Additionally, Redis Object Cache uses a range of additional caching techniques that reduce the time taken to read and write from the server. These caching techniques not only save time, but they also protect user data from latency issues. The plugin also has a wide array of features such as command line administration, support for memcached as a fallback option, and the ability to flush data without restarting the server.

Pros of Using Redis Object Cache

Faster Performance: Redis Object Cache provides a significant increase in speed, allowing WordPress websites to be more performant. Caching database queries, page loads, and more, the improved performance means more reliable and stable experiences for users. Furthermore, fewer resources and time will also be needed from the server.

Better Security: Redis Object Cache is more secure than other caches, as it’s an atomic operation. This means that the information stored is checked to see if it’s up to date before any operations occur. Additionally, Redis Object Cache is only available to authorized users which makes it a secure way to cache data.

Scalability: Redis Object Cache is also a good option for scaling a WordPress website. With built-in support for clusters, the Redis server can easily be scaled up or down as needed. This is beneficial as the website will be able to withstand spikes in traffic while managing the cost associated with running the server.

Great for Developers: Developers will find Redis Object Cache especially useful. Functions can be quickly cached, and the data stored is easily accessible, making it easier for developers to stay efficient and productive. Redis Object Cache can also be easily integrated into development pipelines, meaning new code can be tested and deployed quickly.

Easy Setup and Maintenance: Redis Object Cache is relatively straightforward to install and will normally require only a few changes to the WordPress configuration. Additionally, once the plugin is installed, it's straightforward to maintain. Regular updates to the plugin will ensure that the cache is running effectively and securely.

Cons of Using Redis Object Cache

Technically Challenging to Use: Using Redis for WordPress caching can be a bit tricky and require a good amount of technical skill and know-how. If you're not used to using caching technologies or Redis, you'll need to learn how to use it and ensure that your server is configured correctly.

High Resource Requirement: Using the Redis Object Cache plugin increases the resources needed to run your WordPress website, as it requires more RAM and CPU usage, and stores the cache on the RAM which increases the server load.

Intermittent Support: The Redis Object Cache plugin can be finicky and sometimes act unpredictably. It can be difficult to understand why the plugin isn't working correctly and troubleshoot any issue that may arise.

Not Widely Used: The Redis Object Cache plugin is not widely used. This means that if you have a problem with the plugin you won't have as many people out there who can help with it as you would with more popular caching solutions.

Costly: Using the Redis Object Cache plugin can be quite costly. Depending on the hosting environment and configuration you require, the cost of running Redis can be quite high.
