Data Caching: Powered by Redis

At Xano, we understand that building powerful and efficient applications requires more than just writing code. That's why we've integrated Redis, an open-source data caching framework, into our platform. With Redis, you can store data in memory, ensuring lightning-fast retrieval and processing times for your applications.

In this guide, we'll explore the different data caching functions available in Xano, powered by Redis. These functions will help you take full advantage of in-memory data storage, allowing you to build high-performance applications without the hassle of complex setup or coding.

Accessing the Data Caching Functions

To get started with the data caching functions, follow these simple steps:

1. Log in to your Xano account and navigate to the Function Stack.
2. Locate the "Data Caching" section, usually the third option from the top.

Note that data caching functions are only available on our dedicated resource plans, ensuring optimal performance and scalability for your applications.

Setting a Cache Value

One of the fundamental operations in data caching is setting a value in the cache. Redis uses a key-value pair system, where you define a unique key to identify and retrieve your cached data. Here's how to set a cache value in Xano:

1. In the Function Stack, click on "Data Caching" and then select "Set a Cache Value."
2. Define a unique key for your cached data, e.g., `key123`.
3. Enter the data you want to cache, which can be a variable or a static value. For example, let's use the number `100`.
4. Specify the Time to Live (TTL) in seconds, which determines how long the cached value will be stored in memory. Set it to `0` to store the value indefinitely.
5. Click "Save" to store the cached value.

Retrieving a Cache Value

Once you've set a cache value, you can easily retrieve it using the "Get a Cache Value" function. Here's how:

1. In the Function Stack, click on "Data Caching" and then select "Get a Cache Value."
2. Enter the key associated with the cached value you want to retrieve, e.g., `key123`.
3. The cached value will be stored in a return variable, allowing you to manipulate or use the data throughout your function stack.

Additional Data Caching Functions

Xano provides several other data caching functions to help you manage and manipulate cached data more effectively:

• Has Cache Value: Check if a specific key exists in the cache. Returns a Boolean value (true or false).
• Delete Cache Value: Remove a cached value from memory by providing its key.
• Increment Cache Value: Increase the value associated with a specific key by a specified amount. Useful for implementing counters or tracking metrics.
• Decrement Cache Value: Decrease the value associated with a specific key by a specified amount.
• Get Cache Keys: Retrieve an array of all existing cache keys, optionally filtered by a wildcard pattern.
• Rate Limit: Implement rate limiting for your API endpoints by defining a maximum number of allowed requests within a specific time frame.

Optimizing Performance with Data Caching

Data caching is a powerful technique that can significantly improve the performance and scalability of your applications. By storing frequently accessed data in memory, you can reduce the load on your database and minimize response times, providing a seamless user experience.

Xano's data caching functions, powered by Redis, make it easy to leverage the benefits of in-memory data storage without the complexity of setting up and managing a separate caching system. Whether you're building a high-traffic web application, a real-time data processing pipeline, or a mobile app with demanding performance requirements, data caching can help you achieve your goals more efficiently.
