MySQL Document Store Video Series

I am starting a series of videos on the MySQL Document Store. The Document Store allows those who do not know Structured Query Language (SQL) to use a database without having to know the basics of relational databases, set theory, or data normalization. The goal is to have sort 2-3 minute episodes on the various facets of the Document Store including the basics, using various programming languages (Node.JS, PHP, Python), and materializing free form schemaless, NoSQL data into columns for use with SQL.

The first Episode, Introduction, can be found here.

Please provide feedback and let me know if there are subjects you would want covered in the near future.

MySQL Document Store: creating generated columns like a boss ;)

Last Thursday, I was introducing MySQL Document Store in Ghent, BE at Percona University.

I was explaining how great is this technology and how MySQL can replace your NoSQL database but still provides you all the benefits from a RDBMS.

This is the full presentation:

Introduction to MySQL Document Store from Frederic Descamps

Then somebody came with a nice question. Let me put first some context:

  • we will create a collection to add people in it
  • we will create a virtual column on the age
  • we will index that column
  • we will query and add records to that collection

Collection creation and add some users

How X Plugin Works Under the Hood

In this blog post, we’ll look at what MySQL does under the hood to transform NoSQL requests to SQL (and then store them in InnoDB transactional engine) when using the X Plugin.

X Plugin allows MySQL to function as a document store. We don’t need to define any schema or use SQL language while still being a fully ACID database. Sounds like magic – but we know the only thing that magic does is make planes fly!

Alexander already wrote a blog post exploring how the X Plugin works, with some examples. In this post, I am going to show some more query examples and how they are transformed.

I have enabled the slow query …

Introduction into storage engine troubleshooting: Q & A

In this blog, I will provide answers to the Q & A for the “Introduction into storage engine troubleshooting” webinar.

First, I want to thank everybody for attending the July 14 webinar. The recording and slides for the webinar are available here. Below is the list of your questions that I wasn’t able to answer during the webinar, with responses:

Q: At which isolation level do 

pt-online-schema-change

 and 

pt-archive

  copy data from a table?

A: Both tools do not change the server’s default transaction isolation level. Use either

Using MySQL 5.7 Document Store with Internet of Things (IoT)

In this blog post, I’ll discuss how to use MySQL 5.7 Document Store to track data from Internet of Things (IoT) devices.

Using JSON in MySQL 5.7

In my previous blog post, I’ve looked into MySQL 5.7.12 Document Store. This is a brand new feature in MySQL 5.7, and many people are asking when do I need or want to use the JSON or Document Store interface?

Storing data in JSON may be quite useful in some cases, for example:

  • You already have a JSON (i.e., from external feeds) and need to store it anyway. Using the JSON datatype will be more convenient and more efficient.
  • For the Internet of Things, specifically, when storing events from …

Looking inside the MySQL 5.7 document store

In this blog, we’ll look at the MySQL 5.7 document store feature, and how it is implemented.

Document Store

MySQL 5.7.12 is a major new release, as it contains quite a number of new features:

  1. Document store and “MongoDB” like NoSQL interface to JSON storage
  2. Protocol X / X Plugin, which can be used for asynchronous queries (I will write about it as well)
  3. New MySQL shell

Peter already wrote the document store overview; in this post, I will look deeper into the document store implementation. In my next post, I will demonstrate how to use document store for Internet of Things (IoT) and event logging.

MySQL 5.7.12 – Part 5: Connector/Node.js

In part 2 of this series of blog posts about MySQL 5.7.12 you could read about our new X Protocol for MySQL. Part 3 gave a glance on our new common basic API, the DevAPI. What’s a protocol and an API without clients using it?…

MySQL 5.7.12 – Part 4: A new MySQL Command Line Shell

The classic MySQL command line tool is how most users – developers and administrators – interact with a MySQL server. From administrative tasks to trying out queries, it wouldn’t be far-fetched to call it the face of MySQL.

With a new programming interface built into the MySQL Server, we need to properly support it at the client side in connectors, tools and of course, the command line client.…
