Redis is an open source, advanced key-value store and an apt solution for building highperformance, scalable web applications.

Redis has three main peculiarities that sets it apart.

• Redis holds its database entirely in the memory, using the disk only for persistence.

• Redis has a relatively rich set of data types when compared to many key-value data stores.

• Redis can replicate data to any number of slaves.

Redis Advantages

Following are certain advantages of Redis.

• Exceptionally fast − Redis is very fast and can perform about 110000 SETs per second, about 81000 GETs per second.

• Supports rich data types − Redis natively supports most of the datatypes that developers already know such as list, set, sorted set, and hashes. This makes it easy to solve a variety of problems as we know which problem can be handled better by which data type.

• Operations are atomic − All Redis operations are atomic, which ensures that if two clients concurrently access, Redis server will receive the updated value.

• Multi-utility tool − Redis is a multi-utility tool and can be used in a number of use cases such as caching, messaging-queues (Redis natively supports Publish/Subscribe), any short-lived data in your application, such as web application sessions, web page hit counts, etc.

Redis Versus Other Key-value Stores

• Redis is a different evolution path in the key-value DBs, where values can contain more complex data types, with atomic operations defined on those data types.

• Redis is an in-memory database but persistent on disk database, hence it represents a different trade off where very high write and read speed is achieved with the limitation of data sets that can't be larger than the memory.

• Another advantage of in-memory databases is that the memory representation of complex data structures is much simpler to manipulate compared to the same data structure on disk. Thus, Redis can do a lot with little internal complexity.

In this chapter, you will learn about the environmental setup for Redis.

Install Redis on Ubuntu

To install Redis on Ubuntu, go to the terminal and type the following commands −

This will install Redis on your machine.

Start Redis

Check If Redis is Working

This will open a redis prompt.

In the above prompt, 127.0.0.1 is your machine's IP address and 6379 is the port on which Redis server is running. Now type the following PING command.

This shows that Redis is successfully installed on your machine.

Install Redis Desktop Manager on Ubuntu

To install Redis desktop manager on Ubuntu, just download the package from https://redisdesktop.com/download

Open the downloaded package and install it.

Redis desktop manager will give you UI to manage your Redis keys and data.

In Redis, there is a configuration file (redis.conf) available at the root directory of Redis. Although you can get and set all Redis configurations by Redis CONFIG command.

Syntax

Following is the basic syntax of Redis CONFIG command.

Example

To get all configuration settings, use * in place of CONFIG_SETTING_NAME

Example

Edit Configuration

To update configuration, you can edit redis.conf file directly or you can update configurations via CONFIG set command.

Syntax

Following is the basic syntax of CONFIG SET command.

Example

Redis supports 5 types of data types.

Strings

Redis string is a sequence of bytes. Strings in Redis are binary safe, meaning they have a known length not determined by any special terminating characters. Thus, you can store anything up to 512 megabytes in one string.

Example

In the above example, SET and GET are Redis commands, name is the key used in Redis and tutorialspoint is the string value that is stored in Redis.

Note − A string value can be at max 512 megabytes in length.

Hashes

A Redis hash is a collection of key value pairs. Redis Hashes are maps between string fields and string values. Hence, they are used to represent objects.

Example

In the above example, hash data type is used to store the user's object which contains basic information of the user. Here HMSET, HGETALL are commands for Redis, while user − 1 is the key.

Every hash can store up to 2³² - 1 field-value pairs (more than 4 billion).

Lists

Redis Desktop Manager Dmg

Redis Lists are simply lists of strings, sorted by insertion order. You can add elements to a Redis List on the head or on the tail.

Example

The max length of a list is 2³² - 1 elements (4294967295, more than 4 billion of elements per list).

Sets

Redis Sets are an unordered collection of strings. In Redis, you can add, remove, and test for the existence of members in O(1) time complexity.

Example

Note − In the above example, rabitmq is added twice, however due to unique property of the set, it is added only once.

The max number of members in a set is 2³² - 1 (4294967295, more than 4 billion of members per set).

Sorted Sets

Redis Sorted Sets are similar to Redis Sets, non-repeating collections of Strings. The difference is, every member of a Sorted Set is associated with a score, that is used in order to take the sorted set ordered, from the smallest to the greatest score. While members are unique, the scores may be repeated.

Example

Redis commands are used to perform some operations on Redis server.

To run commands on Redis server, you need a Redis client. Redis client is available in Redis package, which we have installed earlier.

Syntax

Following is the basic syntax of Redis client.

Example

Following example explains how we can start Redis client.

To start Redis client, open the terminal and type the command redis-cli. This will connect to your local server and now you can run any command.

In the above example, we connect to Redis server running on the local machine and execute a command PING, that checks whether the server is running or not.

Run Commands on the Remote Server

To run commands on Redis remote server, you need to connect to the server by the same client redis-cli

Syntax

Example

Following example shows how to connect to Redis remote server, running on host 127.0.0.1, port 6379 and has password mypass.

Redis keys commands are used for managing keys in Redis. Following is the syntax for using redis keys commands.

Syntax

Example

In the above example, DEL is the command, while tutorialspoint is the key. If the key is deleted, then the output of the command will be (integer) 1, otherwise it will be (integer) 0.

Redis Keys Commands

Following table lists some basic commands related to keys.

Redis strings commands are used for managing string values in Redis. Following is the syntax for using Redis string commands.

Syntax

Example

In the above example, SET and GET are the commands, while tutorialspoint is the key.

Redis Strings Commands

Following table lists some basic commands to manage strings in Redis.

Redis Hashes are maps between the string fields and the string values. Hence, they are the perfect data type to represent objects.

In Redis, every hash can store up to more than 4 billion field-value pairs.

Example

In the above example, we have set Redis tutorials detail (name, description, likes, visitors) in hash named ‘tutorialspoint’.

Redis Hash Commands

Following table lists some basic commands related to hash.

Redis Lists are simply lists of strings, sorted by insertion order. You can add elements in Redis lists in the head or the tail of the list.

Maximum length of a list is 2³² - 1 elements (4294967295, more than 4 billion of elements per list).

Example

In the above example, three values are inserted in Redis list named ‘tutorials’ by the command LPUSH.

Redis Lists Commands

Following table lists some basic commands related to lists.

Redis Sets are an unordered collection of unique strings. Unique means sets does not allow repetition of data in a key.

In Redis set add, remove, and test for the existence of members in O(1) (constant time regardless of the number of elements contained inside the Set). The maximum length of a list is 2³² - 1 elements (4294967295, more than 4 billion of elements per set).

Example

In the above example, three values are inserted in Redis set named ‘tutorials’ by the command SADD.

Redis Sets Commands

Following table lists some basic commands related to sets.

Redis Sorted Sets are similar to Redis Sets with the unique feature of values stored in a set. The difference is, every member of a Sorted Set is associated with a score, that is used in order to take the sorted set ordered, from the smallest to the greatest score.

In Redis sorted set, add, remove, and test for the existence of members in O(1) (constant time regardless of the number of elements contained inside the set). Maximum length of a list is 2³² - 1 elements (4294967295, more than 4 billion of elements per set).

Example

In the above example, three values are inserted with its score in Redis sorted set named ‘tutorials’ by the command ZADD.

Redis Sorted Sets Commands

Following table lists some basic commands related to sorted sets.

Redis HyperLogLog is an algorithm that uses randomization in order to provide an approximation of the number of unique elements in a set using just a constant, and small amount of memory.

HyperLogLog provides a very good approximation of the cardinality of a set even using a very small amount of memory around 12 kbytes per key with a standard error of 0.81%. There is no limit to the number of items you can count, unless you approach 2⁶⁴ items.

Example

Following example explains how Redis HyperLogLog works.

Redis HyperLogLog Commands

Following table lists some basic commands related to Redis HyperLogLog.

Redis Pub/Sub implements the messaging system where the senders (in redis terminology called publishers) sends the messages while the receivers (subscribers) receive them. The link by which the messages are transferred is called channel.

In Redis, a client can subscribe any number of channels.

Example

Following example explains how publish subscriber concept works. In the following example, one client subscribes a channel named ‘redisChat’.

Now, two clients are publishing the messages on the same channel named ‘redisChat’ and the above subscribed client is receiving messages.

Redis PubSub Commands

Following table lists some basic commands related to Redis Pub/Sub.

Redis transactions allow the execution of a group of commands in a single step. Following are the two properties of Transactions.

• All commands in a transaction are sequentially executed as a single isolated operation. It is not possible that a request issued by another client is served in the middle of the execution of a Redis transaction.

• Redis transaction is also atomic. Atomic means either all of the commands or none are processed.

Sample

Redis transaction is initiated by command MULTI and then you need to pass a list of commands that should be executed in the transaction, after which the entire transaction is executed by EXEC command.

Example

Following example explains how Redis transaction can be initiated and executed.

Redis Transaction Commands

Following table shows some basic commands related to Redis transactions.

Redis scripting is used to evaluate scripts using the Lua interpreter. It is built into Redis starting from version 2.6.0. The command used for scripting is EVAL command.

Syntax

Following is the basic syntax of EVAL command.

Example

Following example explains how Redis scripting works.

Redis Scripting Commands

Following table lists some basic commands related to Redis Scripting.

Redis connection commands are basically used to manage client connections with Redis server.

Example

Following example explains how a client authenticates itself to Redis server and checks whether the server is running or not.

Redis Connection Commands

Following table lists some basic commands related to Redis connections.

Redis server commands are basically used to manage Redis server.

Example

Following example explains how we can get all statistics and information about the server.

Redis Server Commands

Following table lists some basic commands related to Redis server.

Redis SAVE command is used to create a backup of the current Redis database.

Syntax

Following is the basic syntax of redis SAVE command.

Example

Following example creates a backup of the current database.

This command will create a dump.rdb file in your Redis directory.

Restore Redis Data

To restore Redis data, move Redis backup file (dump.rdb) into your Redis directory and start the server. To get your Redis directory, use CONFIG command of Redis as shown below.

In the output of the above command /user/tutorialspoint/redis-2.8.13/src is the directory, where Redis server is installed.

Bgsave

To create Redis backup, an alternate command BGSAVE is also available. This command will start the backup process and run this in the background.

Example

Redis database can be secured, such that any client making a connection needs to authenticate before executing a command. To secure Redis, you need to set the password in the config file.

Example

Following example shows the steps to secure your Redis instance.

By default, this property is blank, which means no password is set for this instance. You can change this property by executing the following command.

After setting the password, if any client runs the command without authentication, then (error) NOAUTH Authentication required. error will return. Hence, the client needs to use AUTH command to authenticate himself.

Syntax

Following is the basic syntax of AUTH command.

Example

Redis benchmark is the utility to check the performance of Redis by running n commands simultaneously.

Syntax

Following is the basic syntax of Redis benchmark.

Example

Following example checks Redis by calling 100000 commands.

Following is a list of available options in Redis benchmark.

Example

Following example shows the multiple usage options in Redis benchmark utility.

Redis accepts clients’ connections on the configured listening TCP port and on the Unix socket, if enabled. When a new client connection is accepted, the following operations are performed −

• The client socket is put in non-blocking state since Redis uses multiplexing and non-blocking I/O.

• The TCP_NODELAY option is set in order to ensure that we don't have delays in our connection.

• A readable file event is created so that Redis is able to collect the client queries as soon as new data is available to be read on the socket.

Maximum Number of Clients

In Redis config (redis.conf), there is a property called maxclients, which describes the maximum number of clients that can connect to Redis.

Following is the basic syntax of command.

By default, this property is set to 10000 (depending upon the maximum number of file descriptors limit of OS), although you can change this property.

Example

In the following example, we have set the maximum number of clients to 100000, while starting the server.

Client Commands

Redis is a TCP server and supports request/response protocol. In Redis, a request is accomplished with the following steps −

• The client sends a query to the server, and reads from the socket, usually in a blocking way, for the server response.

• The server processes the command and sends the response back to the client.

Meaning of Pipelining

The basic meaning of pipelining is, the client can send multiple requests to the server without waiting for the replies at all, and finally reads the replies in a single step.

Example

To check the Redis pipelining, just start the Redis instance and type the following command in the terminal.

In the above example, we will check Redis connection by using PING command. We have set a string named tutorial with value redis. Later, we get that keys value and increment the visitor number three times. In the result, we can see that all commands are submitted to Redis once, and Redis provides the output of all commands in a single step.

Benefits of Pipelining

The benefit of this technique is a drastically improved protocol performance. The speedup gained by pipelining ranges from a factor of five for connections to localhost up to a factor of at least one hundred over slower internet connections.

Partitioning is the process of splitting your data into multiple Redis instances, so that every instance will only contain a subset of your keys.

Benefits of Partitioning

• It allows for much larger databases, using the sum of the memory of many computers. Without partitioning you are limited to the amount of memory that a single computer can support.

• It allows to scale the computational power to multiple cores and multiple computers, and the network bandwidth to multiple computers and network adapters.

Disadvantages of Partitioning

• Operations involving multiple keys are usually not supported. For instance, you can't perform the intersection between two sets if they are stored in the keys that are mapped to different Redis instances.

• Redis transactions involving multiple keys cannot be used.

• The partitioning granuliary is the key, so it is not possible to shard a dataset with a single huge key like a very big sorted set.

• When partitioning is used, data handling is more complex. For instance, you have to handle multiple RDB/AOF files, and to get a backup of your data you need to aggregate the persistence files from multiple instances and hosts.

• Adding and removing the capacity can be complex. For instance, Redis Cluster supports mostly transparent rebalancing of data with the ability to add and remove nodes at runtime. However, other systems like client-side partitioning and proxies don't support this feature. A technique called Presharding helps in this regard.

Types of Partitioning

There are two types of partitioning available in Redis. Suppose we have four Redis instances, R0, R1, R2, R3 and many keys representing users like user:1, user:2, .. and so forth.

Range Partitioning

Range partitioning is accomplished by mapping ranges of objects into specific Redis instances. Suppose in our example, the users from ID 0 to ID 10000 will go into instance R0, while the users from ID 10001 to ID 20000 will go into instance R1 and so forth.

Hash Partitioning

In this type of partitioning, a hash function (eg. modulus function) is used to convert the key into a number and then the data is stored in different-different Redis instances.
