With new MySQL Shell 8.0.13 comes a new way to quickly load JSON data sets very quickly.  In a past blog and in several talks I have shown how to use the shell with the Python mode to pull in the data.  But now there is a much faster way to load JSON

Load JSON Quickly Start a copy of the new shell with mysqlsh. Connect to your favorite server \c dave@localhost and then create a new schema session.createSchema('bulk'). Then point you session to the schema just created with \use bulk.  Version 8.0.13 has a new utility function named importJson that does the work.  The first argument is the path to the data set (here the MongoDB restaurant collection) and the second allows you to designate the schema and collection where you wish to have the data stored.  In this example the data set was in the downloads directory of my laptop and I wanted to put it in the newly created 'bulk' schema …

Have you ever heard about VoiceXML? It’s a W3C standard that allows you to build web pages that are accessed by voice! It can be used for services like travel tickets selling, hotel reservation, bank account information and so on. In this post, I’ll give you a general view of how to make a basic hotel reservation application with VoiceXML and how to run it using Glassfish and MySQL.

First of all, for VoiceXML applications, we need a voice gateway. I used Voxeo, it’s free and provides you with phone numbers that you can call for free using Skype. All you need to do is create a free account in Voxeo and register your application by informing it’s URL. After registering you’ll receive the unique phone number for your application.

I’ll assume you already know the basics of VoiceXML syntax for the rest of this …

What excites me is the possibility that this tool is giving to other people. Also, the challenges I’ve faced and the new ideas for the future releases are always source of interest that keep me focused on the project. So I’m looking forward to sharing this with the conference delegates.

pg_chameleon can achieve two tasks in a very simple way. It can setup a permanent replica between MySQL and PostgreSQL, giving the freedom of choice for the right tool for the right job, or can migrate multiple schemas to a PostgreSQL database.

Anybody that want to extend their database experience, taking the best of the two worlds, or who is seeking a simple way to migrate data with minimal downtime will find the presentation interesting.

Since the new 8.0.13 release we publish docker images for a new architecture: aarch64, as part of our normal release process. This means that the mysql/mysql-server docker image will work on both amd64 and aarch64 architectures. The newest images are as usually available on dockerhub. On amd64 machines: [user@amd64host]$ docker pull mysql/mysql-server:8.0.13 [user@aarch64host]$ docker run […]

MySQL Shell is a command-line shell for MySQL Server that has the capability for
interactive and batch code execution.  It also offers a wealth of APIs that make it easier and more efficient to work with and manage MySQL servers. In 8.0.13, we made an effort to make those APIs easily accessible straight from the command line.…

Containers are eating the world. If you have built and deployed an application in production over the last few years, the odds are that you have deployed your code in containers. You might have created and deployed individual containers (Docker, Linux LXC, etc.) directly in the beginning, but quickly switched over to a container orchestration technology like Kubernetes (K8s) or Swarm when you needed to coordinate multi-node deployments and high availability (HA). In this container-driven world, what will the future of the application stack look like? Let’s start with what we need from this “future” application stack.

What Do We Need From This Future Application Stack?

Enterprises require high availability for their business-critical applications. Even the smallest unplanned outage or even a planned maintenance operation can cause lost sales, productivity, and erode customer confidence. Additionally, updating and retrieving data needs to be robust to keep up with user demand.

Let’s take a look at how Tungsten Clustering helps enterprises keep their data available and globally scalable, and compare it to Amazon’s RDS running MySQL (RDS/MySQL).

Replicas and Failover What does RDS do?

Having multiple copies of a database is ideal for high availability. RDS/MySQL approaches this with “Multi-AZ” deployments. The term “Multi-AZ” here is a bit confusing, as enabling this simply means a single “failover replica” will be created in a different availability zone from the primary database instance. …
