SQL vs Redis: Which one is better for your application? Leave a comment

A hundred connecting clients reading from SQL/Redis, each reading loops, and see which one finishes earlier. So, in short, Redis helps you access your data faster while collecting data quickly from your users. On the other hand, MySQL is a database and a full blown data store. MySQL is suitable for permanently storing data, and also exposes a rich API for making it easy to query and search its data. Redis and MySQL are really two very different technologies. Redis primarily serves as a cache for storing data temporarily as a key-value store.

# Note that Redis will write a pid file in /var/run/redis.pid when daemonized. In this article, we will be discussing the https://www.globalcloudteam.com/tech/redis/ performance benchmarks of Redis and MySQL. We will start with the introduction and installation of Redis over Ubuntu.

Microsoft SQL Server vs Redis

We’ll look at how Redis supports complex data structures and indexing, which can enable faster querying compared to SQL databases. We’ll also examine how Redis can be horizontally scaled by adding more nodes, which can increase throughput and availability compared to vertically scaling a single SQL database instance. An RDBMS that implements object-oriented features such as user-defined types, inheritance, and polymorphism is called an object-relational database management system . Oracle Database has extended the relational model to an object-relational model, making it possible to store complex business models in a relational database.

If you choose not to you will still have the networked, in-memory cache. But should you choose to back up the data, you will decide if you want to dump the dataset to the disk, or if you would rather append commands to a disk-based log. But enough about the background, let’s look at the differences between Redis and MySQL so we can get a better understanding of the database. We’ll examine the unique features and benefits of Redis and how it compares to other databases in terms of data modeling, querying, scalability, performance, and more. We’ll also explore some of the advantages and disadvantages of Redis, and discuss how it can be used in various use cases such as caching, real-time analytics, and messaging.

Predictive Modeling w/ Python

I was just pointing out ways to further skew/tweak/test in your benchmarks. SQL and Redis are both powerful tools for data storage and retrieval. @TonyLin It’s both, it’s fast because it’s in-memory and because Redis also has a pretty good implementation of cutting edge data models to help it do its work as best as it can. » moreCompetitive advantagesRedis Enterprise is a robust in-memory database platform built by the people who… If you stick to Linux server, the PostgreSQL or MySQL provided with your distribution are straightforward to install (i.e. apt install postgresql).

Why Redis is better than SQL

Connect and share knowledge within a single location that is structured and easy to search. Redis performance is related to many factors, which will be described in detail in the third part. For example, the network status of the client, whether to use pipelining and the linked client.

Another RDBMS and NoSQL showdown…

You should also keep in mind that SQLite has been around for a long time and is very highly optimized. It’s limited by ACID compliance, but you can actually turn that off , and get it even faster. Asking multiple questions in a post is explicitly not allowed. # others with access to the host running redis-server.

Why Redis is better than SQL

BTW, you can make sqlite even faster as well by doing bulk inserts. Apples to Oranges, a fruit is still a fruit – you have a goal to achieve. Everything else of how that goal is achieved is semantics to the core objective. The question was in relation to performance and speed in one solution to another. If you look too close to the details, or apples to apples as you say, the difference is almost negligible with on par systems. If you need to keep it for a long time then I’d recommend against such a configuration.

MySQL Only Source Code

Because it stores data in memory in the form of key value pair, we can store frequently accessed data in cache which are not changes very frequently. Reading from cache is much faster than database. Redis is one of the best solution in distributed cache market. We will examine how these differences affect data modeling, querying, and scalability in Redis and SQL databases.

  • Started by core members of the original MySQL team, MariaDB actively works with outside developers to deliver the most featureful, stable, and sanely licensed open SQL server in the industry.
  • Redis stands for Remote Dictionary Server which is an in-memory data structure project implementing a distributed, in-memory key–value database with optional durability.
  • Redis provides data structures such as strings, hashes, lists, sets, sorted sets with range queries, bitmaps, hyperloglogs, geospatial indexes, and streams.
  • It has the advantages and capabilities of NoSQL databases.
  • The reputation requirement helps protect this question from spam and non-answer activity.
  • Store application data in MySQL as the system of record.
  • Honestly both databases will do the job just fine.

Another reason Redis is fast is a bit unintuitive. It is primarily single-threaded which raises some questions. As a key-value system, the maximum load level is 10W / s, and the set and get time consumption levels are 10ms and 5ms. Using pipelines can improve the performance of Redis operations. To understand how fast Redis is going, you need to have an assessment tool.

Redis vs SQL Server performance

Redis, however, isn’t NoSQL replacement for classic relational databases since it doesn’t support many standard features of RDBMS world such as querying of your data which might slow it down. Replacement are rather document databases like MongoDB or CouchDB and redis is great at supplementing specific functionality where https://www.globalcloudteam.com/ speed and support for advanced data structures comes handy. Redis is an open source , in-memory data structure store, used as a database, cache, and message broker. Redis provides data structures such as strings, hashes, lists, sets, sorted sets with range queries, bitmaps, hyperloglogs, geospatial indexes, and streams.

Why Redis is better than SQL

Microsoft SQL Server is a widely used relational database. Just like any other RDBMS, SQL Server encounters performance issues as the data it stores grows to larger volumes. Even with all of the fine tuning and a heavy investment in the physical infrastructure, SQL Server can only perform a few thousand operations per second.

Related Comparisons

While it is true that Redis can be configured to write back to a database or file under the hood, Redis itself is neither of these things. Instead, Redis is meant to store data which generally would be considered volatile. As it can be easily seen from the graphical representation given above, as the number of requests increases significantly, Redis starts outperforming by a significant margin.
