How much data can be cached in Redis?

You can store up to 512 megabytes in a Redis string. It can store any type of data, like text, integers, floats, videos, images, or audio files. In this example, SET and GET are Redis commands, which we will discuss later. name is the key, and educative is the string value that we are storing.

How long can a Redis value be?

Redis Strings are binary safe, this means that a Redis string can contain any kind of data, for instance a JPEG image or a serialized Ruby object. A String value can be at max 512 Megabytes in length.

What is Redis cache in Azure?

Azure Cache for Redis is a fully managed, in-memory cache that enables high-performance and scalable architectures. Use it to create cloud or hybrid deployments that handle millions of requests per second at sub-millisecond latency—all with the configuration, security and availability benefits of a managed service.

How is data stored in Redis cache?

Redis is an in-memory non-relational key-value store (sometimes referred to as a data structure server). This means that it stores data based on keys and values — think of it as a giant dictionary that uses words and their definitions to store information.

Why Redis cache is fast?

The ability to work with different types of data is what really makes Redis an especially powerful tool. A key value could be just a string as is used with Memcached. All of the data is stored in RAM, so the speed of this system is phenomenal, often performing even better than Memcached.

How does caching work Redis?

Redis is an open-source, highly replicated, performant, non-relational kind of database and caching server. It works by mapping keys to values with a sort of predefined data model. Its benefits include: Mapped key-value-based caching system, almost comparable to memcached.

How does a Redis Cache work?

How big should Redis cache be?

Azure Cache for Redis performance

Pricing tier	Size	1-KB value size
Standard cache sizes		Requests per second (RPS) Non-SSL
C0	250 MB	15,000
C1	1 GB	38,000
C2	2.5 GB	41,000

How is Redis so fast?

Redis is a data structure server. As a key-value data store, Redis is similar to Memcached, although it has two major advantages over that option: support of additional datatypes and persistence. All of the data is stored in RAM, so the speed of this system is phenomenal, often performing even better than Memcached.
