Which storage engine is best for MySQL

So, we are here to help you find the best storage engine for MySQL. Basically, during the creation of a database is created, selecting the correct storage engine is one of the most overlooked factors which can have repercussions in the overall performance of the database, especially as the database grows.

 

In many cases, developers go on with the default choice and continue developing the project. While this is natural and can be done, it can lead to unexpected negative results on the database performance, backup process, and data integration during the application life cycle, for instance, when you decide to implement advanced features such as analytics and MySQL dashboards.

 

To avoid these potential risks, we have curated a list for you to have a closer look at some of the most widely used storage engines compatible with MySQL.This shall give you a bird’s eye on every commonly used storage engine for MySQL, what they are designed to do, and how they can be used to their maximum potential to meet organizational goals.

InnoDB

 

This is one of the best storage engines for MySQL. It is also the default storage engine in MySQL 5.7. InnoDB is a versatile and robust storage engine offering:

 

  • Complete ACID(Atomicity, Consistency, Isolation, and Durability) compliance.
  • It is equipped with a commit, rollback, and crash-recovery functions for any failure.
  • Integrated Row-level locking to ensure fewer lock conflicts.
  • In-built FOREIGN KEY for enabling referential integrity constraints.
  • InnoDB increasing multi-user concurrency through non-locking reads.

 

With a combination of all these functionalities, it is safe to say why it is chosen as the default storage engine for MySQL. It offers almost all the attributes that would be required of a storage engine.

 

 

MyISAM

 

While MyISAM is also a popular MySQL storage engine, here are the functionalities which truly set it apart:

 

  • Search Indexes with the capability of Full-Text.
  • Locking enabled on a table-level.
  • A lack of supporting transactions

 

Although it is a high-speed storage engine in MySQL, MyISAM is best suited for read-heavy and mostly read applications in MySQL in cases such as data warehousing and heavy web applications which do not require transaction support or can function without ACID compliance.

 

NDB, also known as NDBCLUSTER

 

Being a popular choice as a storage engine in MySQL, the NDB is your best option if you have a clustered environment for your database. In addition to that, it is the best option if you need:

 

  • Distributed computing in your project.
  • A very High-redundancy occurrence
  • High-availability ratio
  • The highest possible uptime, literally.

 

Also, do note that the support for this MySQL storage engine is not available in the distribution of MySQL Server 5.7 binaries. You shall have to update the server to the latest binary update of the MySQL Cluster. However, if you are already working in a clustered environment, this will not be very challenging.

CSV

 

This is a mighty and easy to use storage engine on MySQL. It is prevalent among databases where the data has to be shared with multiple applications that only support CSV formats.

 

As the name suggests, the tables in this are stored as Comma Separated Value TXT files. Although making data sharing among scripts and applications more straightforward, the CSV storage engine has one major drawback. The CSV files are not indexed; therefore, the data must be stored in the InnoDB table until you have proceeded to the Import/Export phase.

 

 

Wrapping Up

 

Now that you have gained some perspective on some of the most popular storage engines for MySQL, it is time to look back and make a decision.

 

Which is the best of them all?

 

While looking at all the advantages, disadvantages, and use cases of all the storage engines for MySQL, it is safe to say that InnoDB is the best among them all.

 

Apart from being the default storage engine (well, that is a stable point in itself), it has so much to offer while being robust and performance-enhancing.

 

So, it is our professional advice to stick with MySQL’s default storage engine, i.e., InnoDB, unless and until you have some scaling problems with your current database engine and migrating to some other seems to be the only possible solution.
