Develop By Example – Creating schemas and collections using Node.js

In a previous post we explained how to connect to a MySQL server configured as a document store using the new MySQL Connector/Node.js. In this post we are going to explain how to create a schema, create a collection and add documents to the collection.

Creating a new schema is very easy; the following code demonstrates how to do it:

var mysqlx = require('mysqlx');
mysqlx.getSession({
  host: 'host',
  port: '33060',
  dbUser: 'root',
  dbPassword: 'my pass'
}).then(function (session) {
  session.createSchema('mySchema').then(function(schema){
    console.log('Schema created');
    session.close();
  });
}).catch(function (err) {
  console.log(err.message);
  console.log(err.stack);
});

In the previous code example we created a connection and then used the XSession object to create a schema, finally we closed the connection.

The first …

Creating An External Slave For A Live AWS Aurora Instance

Overview

When working with Amazon AWS Aurora, there are some steps to consider when trying to get data out of an active Aurora master into a slave, potentially into a EC2 instance or offsite in another data centre. Creating an external mysql to Aurora gives the option to move out of Aurora, or to have the flexibility to move data around as desired. With AWS RDS instances this task is pretty simple because you can do the following :

  1. Create a read replica
  2. Stop the slave process
  3. Capture the positioning
  4. Dump the database

With Aurora it’s a little trickier, because a read replica in Aurora has no slave process. All of the replication is handled on the back end and cannot be controlled. However, setting up an external slave can be done.

Using Ceph with MySQL

Over the last year, the Ceph world drew me in. Partly because of my taste for distributed systems, but also because I think Ceph represents a great opportunity for MySQL specifically and databases in general. The shift from local storage to distributed storage is similar to the shift from bare disks host configuration to LVM-managed disks configuration.

Most of the work I’ve done with Ceph was in collaboration with folks from Red Hat (mainly Brent Compton and Kyle Bader). This work resulted in a number of talks presented at the Percona Live conference in April and the Red Hat Summit San Francisco at the end of June. I could write a lot about using Ceph with databases, and I hope this post …

Eight Ways To Ensure Your Applications Are Enterprise-Ready

When it comes to building database applications and solutions, developers, DBAs, engineers and architects have a lot of new and exciting tools and technologies to play with, especially with the Hadoop and NoSQL environments growing so rapidly.

While it’s easy to geek out about these cool and revolutionary new technologies, at some point in the development cycle you’ll need to stop to consider the real-world business implications of the application you’re proposing. After all, you’re bound to face some tough questions, like:

Why did you choose that particular database for our mission-critical application? Can your team provide 24/7 support for the app? Do you have a plan to train people on this new technology? Do we have the right hardware infrastructure to support the app’s deployment? How are you going to ensure there won’t be any bugs or security vulnerabilities?

If you don’t have a plan for …

Webinar July 14, 10 am PDT: Introduction into storage engine troubleshooting

Please join Sveta Smirnova for a webinar Thursday, July 14 at 10 am PDT (UTC-7) on an Introduction Into Storage Engine Troubleshooting.

The number of MySQL storage engines provide great flexibility for database users, administrators and developers. At the same time, engines add an extra level of complexity when it comes to troubleshooting issues. Before choosing the right troubleshooting tool, you need to answer the following questions (and often others):

  • What part of the server is responsible for my issue?
  • Was a lock set at the server or engine level?
  • Is a standard or engine-specific tool better?
  • Where are the engine-specific options?
  • How to …
