Redis for Enterprise: Fast Flexible and Feature-Rich

Redis is a popular open-source in-memory data structure store that is used to provide low latency data access for a variety of use cases. It has a client-server architecture where clients can interact with the server by sending requests and receiving responses.

Redis is known for its fast read and write performance, which is why it is commonly used in applications that require real-time data updates. Part 1: Installing and

Configuring Redis

Installing Redis from Source

To install Redis from source, you will need to download the source code from the official Redis website and extract it on your machine. You will then need to compile the source code by running the make command in the extracted directory.

Once the compilation is complete, you can start Redis by running the redis-server command in the bin directory.

Configuring Redis

After installing Redis, you will want to configure it to your specific needs. Some common configurations include changing the default port that Redis listens on and enabling password authentication for Redis connections.

Additionally, you may want to configure Redis to ensure secure connections, such as by using TLS/SSL. Part 2:to Redis

Getting Started

To get started with Redis, you will need to install it and have a basic understanding of how it works. Redis is an in-memory data store, which means it stores data in RAM instead of on disk.

This allows Redis to offer extremely fast data access times. Redis is also known for its ability to handle multiple data structures, which makes it a versatile tool for storing and managing data.

Redis as a Python Dictionary

In Python, dictionaries are used to store key-value pairs. Redis can also be used in a similar fashion, as a key-value store.

Redis allows you to store different data types as values, which include strings, hashes, lists, sets, and more. This allows you to store more than just simple key-value pairs, making Redis a powerful data storage system.

More Data Types in Python vs Redis

While Python has its own set of data types, Redis offers a wider range of data types that it can handle. For example, Redis allows you to store and manipulate lists, which can be used for tasks like message queues.

Redis also allows you to store sets of data, which can be helpful for implementing unique user IDs for user accounts.


Redis is an excellent tool for storing and managing data, offering both fast read and write times, as well as the ability to handle multiple data types. By understanding how to install and configure Redis, as well as how to use it with Python and its various data types, you can take advantage of this powerful tool in your projects.

Redis-py is a Python package that provides a Python interface to Redis, allowing developers to interact with Redis databases using Python code. Redis-py is built on top of the Redis protocol and implements Redis commands using Python functions.

Redis-py offers a comprehensive set of features, including key expiration, persistence, and snapshotting, making it a popular choice for Python developers. Using redis-py: Redis in Python

redis-py provides full support for working with Redis databases in Python.

To get started with redis-py, you will need to install it using pip, the package manager for Python. After installing redis-py, you can connect to a Redis server using the Redis class.

The connection parameters such as host, port, password and database can be passed to the Redis class constructor.

First Steps

To connect to Redis, you can use the Redis class from the redis-py package. You can create a Redis client by instantiating the Redis class and passing it connection parameters, such as the host and port.

After connecting to Redis, you can manipulate data by calling Redis commands using the client.

Allowed Key Types

Redis allows you to store a variety of data types as keys, including strings, hashes, lists, sets, and more. Redis-py supports all of these key types, allowing developers to store and manipulate data using Python code.


As an example, let’s consider the case of an online store called, which sells hats online. Using Redis-py, we can store information about hats, such as their name, price, and inventory status.

We can use the set command to set the value of a key, such as the name of a hat, and the get command to retrieve the value of a key:


import redis

# Connect to Redis server

r = redis.Redis(host=’localhost’, port=6379, db=0)

# Add a hat to our inventory

r.set(‘hat_1_name’, ‘Fedora’)

r.set(‘hat_1_price’, 29.99)

r.set(‘hat_1_inventory’, 100)

# Retrieve hat information

hat_name = r.get(‘hat_1_name’)

hat_price = r.get(‘hat_1_price’)

hat_inventory = r.get(‘hat_1_inventory’)


Using Key Expiry

Redis-py provides support for setting a time-to-live (TTL) on a key, after which it will automatically expire. This is useful for storing data that needs to be deleted after a certain amount of time, such as session data or temporary data that is no longer needed.


# Add a hat to our inventory that expires in 30 minutes

r.setex(‘hat_2_name’, 1800, ‘Beanie’)

“`, Part 2 can also use Redis-py as a cache for frequently accessed data. For example, let’s say that displays the top 5 most popular hats to its customers.

We can store the hat popularity data in Redis and update it each time a customer purchases a hat:


# Increment the popularity count for a hat


# Get the top 5 most popular hats

popular_hats = r.zrevrange(‘popular_hats’, 0, 4, withscores=True)


Persistence and Snapshotting

Redis-py supports persistence and snapshotting, which allows you to save the current state of the Redis database to disk. This ensures that the database can be restored in the event of a system failure or power outage.

Redis-py provides two methods of persistence – RDB persistence and AOF persistence.

Serialization Workarounds

Redis-py uses the built-in Python serialization module, Pickle, to serialize Python objects stored in Redis. However, Pickle is not secure and should not be used to serialize untrusted data.

To avoid Pickle’s limitations, Redis-py provides alternative serialization methods such as JSON and MessagePack.


Redis-py currently does not natively support encryption of data in transit or at rest. To encrypt connections, an SSL/TLS wrapper can be used around the Redis client in python and/or the Redis server.


Redis-py does not natively support data compression, but it is possible to implement compression of the data yourself before storing it in Redis.

Using Hiredis

Hiredis is a C library that provides a faster parser for the Redis protocol than the one that is included with Redis-py by default. Hiredis can significantly speed up processing of Redis responses, improving the performance of Python applications that use Redis.

Redis-py offers Hiredis as an optional CPython module, which can be used by upgrading cPython with the Hiredis package. Redis provides enterprise-grade solutions that can store, manipulate and analyze large volumes of data, making it an ideal choice for enterprise applications.

Redis can be used as a real-time database for streaming applications, a messaging queue system, or an in-memory cache system. It can also be a critical component of a data analytics stack, or improve application performance and scalability in DevOps.

Redis has been designed to scale seamlessly and is used by many large companies as part of their tech stack. In this article, we will look at the use of Redis in enterprise applications.

Using Redis in Enterprise Applications

Redis is increasingly being used in enterprise applications where high throughput and low latency are mission-critical. Redis can be used as a distributed database, allowing multiple Redis instances to be linked together to create high-availability systems.

Additionally, Redis can be used to implement efficient messaging systems that can handle millions of messages per second. Enterprises can also benefit from using Rediss pub/sub system to implement real-time systems, such as chat systems, or real-time data analysis.

Support for Large Data Volumes

Redis is optimized for in-memory access, thereby providing fast data retrieval for data stored in its memory. By providing support for large data volumes, Redis is scalable for managing large databases.

Furthermore, Redis can be used as a distributed cache system, where data is cached in memory to improve performance and reduce the load on backend databases. Redis can be used by teams to share a single in-memory cache to avoid acquiring multiple instances.

Tools for Enterprise-Grade Administration

Redis provides enterprise-grade administration tools to manage Redis instances in a large-scale environment. Redis Enterprise provides an enterprise-grade dashboard that allows administrators to monitor and manage Redis clusters through a web interface.

Redis Enterprise can help enterprises to ensure that Redis instances are running at peak performance by providing real-time performance metrics.

Security and Compliance

Security and compliance are critical in enterprise environments and Redis provides several features to ensure data security. Redis can be secured with TLS/SSL, allowing data to be encrypted and authenticated in transit.

Redis can also provide authentication and authorization mechanisms to ensure that only authorized users are accessing data stored in the database. Redis Enterprise also provides FIPS 140-2 compliant full-disk encryption to store data at rest.

Integration with Python

Redis has excellent Python support, making it easy for Python developers to work with Redis. The redis-py Python package provides a high-level Python interface to Redis that makes it easy to connect, read, and write data to a Redis instance.

Python developers can use Redis with Python web frameworks like Flask and Django to build scalable, performant web applications. Redis can also be used in Python for tasks like caching and messaging to improve application speed and efficiency.
