In my prior blog post on Terraform, I demonstrated building the dependent infrastructure that MySQL implementations need.  Building MySQL isn’t much different, but does identify a need for a Webserver to provide configuration files for Terraform to execute on as was done in my prior MySQL on OCI post, and a Yum Repo Webserver to… Read More »

We’re happy to announce that our newly updated whitepaper MySQL Replication for High Availability is now available to download for free!

MySQL Replication enables data from one MySQL database server to be copied automatically to one or more MySQL database servers.

Unfortunately database downtime is often caused by sub-optimal HA setups, manual/prolonged failover times, and manual failover of applications. This technology is common knowledge for DBAs worldwide, but maintaining those high availability setups can sometimes be a challenge.

In this whitepaper, we discuss the latest features in MySQL 5.6, 5.7 & 8.0 as well as show you how to deploy and manage a replication setup. We also show how …

The past couple of blog entries have been on Geographic Information Systems and Geometric Data.  Visualizing that data with MySQL Workbench makes it easier for me to see what the results really mean.

So how do you get there?

Start Workbench, create a new SQL Tab in your favorite scratch schema, and crate the table below. 

CREATE TABLE `test` (
  `id` INT NOT NULL AUTO_INCREMENT,
  `geom` GEOMETRY NULL,
  PRIMARY KEY (`id`));

Next add some data.

INSERT INTO `test` …

As we continue the development of our Percona Operators to simplify database deployment in Kubernetes (Percona Server for MongoDB Operator 0.3.0 and Percona XtraDB Cluster Operator 0.3.0), one very popular question I get is: how does deployment in Kubernetes affect MySQL performance? Is there a big performance penalty? So I plan to look at how to measure and compare the performance of Kubernetes deployments to bare metal deployments. Kubernetes manages a lot of infrastructure resources like network, storage, cpu, and memory, so we need to look individually at different components.

To begin: I plan to run a single MySQL (Percona Server) instances in …

The last blog entry was very popular and there were lots of requests for some introductory information on the spatial data types. 

Well Known Text Or Binary
I am going to use the GEOMETRY data type over POINT, LINESTRING, or POLYGON as it can store any of those three while the other three can only contain data matching their name (so POINT can holds only point data, etc.). The values are stored in an internal geometry format but it takes wither WKT or WKB formatted data.

Those are Well-Known Text (WKT) or Well-Known Binary (WKB) formats repectively. I am hoping most of your are better with text than binary so the following examples demonstrate how to insert geometry values into a table by converting WKT values to internal geometry format.

So let us start with a …

In this tutorial we'll learn how to build a React application that consumes a third-party REST API using the fetch() API. We'll also use Bootstrap 4 to style the UI.

We'll consume a third-party API available from this link.

We'll also see some basics of React such as:

The state object to hold the state of the app and the setState() method to mutate the state. The componentDidMount() life-cycle method for running code when the component is mounted in the DOM. How to embed JavaScript expressions in JSX using curly braces. How to render lists of data using the map() method and JSX and conditionally render DOM elements using the logical && operator.

React is the most popular UI library for building user interfaces built and used internally by Facebook.

React has many features such as:

Declarative: React makes it easy to build interactive UIs by creating views for each state in your application, …

Percona announces the release of Percona XtraDB Cluster Operator 0.3.0 early access.

The Percona XtraDB Cluster Operator simplifies the deployment and management of Percona XtraDB Cluster in a Kubernetes or OpenShift environment. It extends the Kubernetes API with a new custom resource for deploying, configuring and managing the application through the whole life cycle.

You can install the Percona XtraDB Cluster Operator on Kubernetes or OpenShift. While the operator does not support all the Percona XtraDB Cluster features in this early access release, instructions on how to install and configure it …
