The Redis In-memory Data Store: An Introduction to Redis
Redis is an in-memory, key-value store with many use cases. It is a popular tool among software developers for delivering improved performance to end-users due to its ease of use, rich feature set, and open source status. In this course, you'll explore the various use cases, features, and limitations of the Redis in-memory store. You'll examine the different data types, structures, and client connections supported in Redis. Next, you'll learn how to install Redis and to set up an instance of the Redis server. You'll then learn to carry out basic Redis operations involving string and numeric data, such as create, read, update, and delete (CRUD) operations and key expiration setting.

The Redis In-memory Data Store: Data Structures
Redis offers a variety of data structures and collections which enable developers to deliver several types of high-performing applications to end-users. In this course, you'll learn how to work with Redis's different data structures, namely lists, hashes, and sets. You'll then learn to perform various set operations, such as union, intersection, and set difference. Next, you'll distinguish sorted sets from regular sets and learn how to work with them. You'll then examine the benefits and limitations of HyperLogLog structures and how to use these in Redis. Upon completing this course, you'll be able to compare and work with each of these structures and recognize their use cases.

The Redis In-memory Data Store: Messaging & Streaming
Redis is primarily an in-memory, key-value store, but has many additional use cases. In this course, you'll explore the use cases of Redis that go beyond its use as a database or cache, specifically its application in messaging and streaming. You'll start by setting up communications between Redis clients using the Publish/Subscribe paradigm and the Redis CLI. Next, you'll learn how to set up Redis streams and retrieve data from them using the XREAD command. Finally, you'll use the stream data structure in Redis to record information and communicate messages to a group of consumer processes.

The Redis In-memory Data Store: Working With Redis Clients
Once the primary functions of Redis are implemented, several advanced features can optimize processes further and enable you to work with Python apps. In this course, you'll explore some of these advanced features and how they apply to pipelines, transactions, and locks. You'll learn how to work with these features using both the Redis CLI and Python clients. You'll start by learning how to use both Pub/Sub and pipelines in a Python app with a Redis client. You'll then learn how to define and execute transactions in Redis and use the watch feature. You'll move on to learn how to apply optimizations using features and techniques, such as the pipe mode feature and server-assisted client-side caching. Finally, you'll learn how to use Redis keys and locks to synchronize access to shared Redis resources.

The Redis In-memory Data Store: Administering a Redis Server
Once a Redis server is in place, there are several essential tasks involved in managing it. In this course, you'll explore how to carry out some of these critical tasks, namely assigning user permissions, establishing replacement servers, and setting cache replacement policies. You'll start by learning how to use ACL commands to set user permissions for new users and continue to assign permissions using ACL categories. Next, you'll learn how to duplicate a copy of a Redis server, before setting up a replica of your server and establishing a master-slave relationship between the server and its replica. Finally, you'll learn how to set up a Redis server to function as a cache by applying the least-recently-used (LRU) or least-frequently-used (LFU) cache replacement policies.
