Take Percona’s database security downtime poll.

As Peter Zaitsev mentioned recently in his blog post on database support, the data breach costs can hit both your business reputation and your bottom line. Costs vary depending on the company size and market, but recent studies estimate direct costs ranging in average from $1.6M to 7.01M. Everyone agrees leaving rising security risks and costs unchecked is a recipe for disaster.

Reducing security-based outages doesn’t have a simple answer, but can be a combination of internal and external monitoring, support contracts, enhanced security systems, and a better understanding of …

This blog reports the results of Percona’s high availability poll.

High availability (HA) is always a hot topic. The reality is that if your data is not available, your customers cannot do business with you. In fact, estimates show the average cost of downtime is about $5K per minute. With an average outage taking 40 minutes to correct, you could be looking at a potential cost of $200K if your MySQL instance goes down. Whether your database is on premise, or in public or private clouds, it is critical that your database deployment does not have a potentially devastating single point of failure.

The results from Percona’s high availability poll responses are in:

With the new Group Replication Beta release—0.8 for MySQL 5.7.14—available for download on labs.mysql.com, I expect more and more people to begin engaging in various forms of proof-of-concept attempts. So I wanted to create a “quick start guide” (to replace this outdated getting started post) focused on an example/test Linux environment, that covers how to get started, what a full working example test setup can look like, and also include some best practice and operations advice along the way.…

Shlomi Noach from the the Github engineering team posted the release of a new tool for triggerless online schema migration with MySQL. Although it's mostly targeted at databases using a replication architecture, if you don’t have replicas, or do not wish to use them, you are still able to operate directly on the master. In spite of being a wonderful project and being used in production by

In the previous blog post we explained how work with the collection CRUD operations. In this blog post we are going to explain other functions that are related to document management.

We already know how to create collections, as well as how to add, delete, update and retrieve documents from them. But, how can we add a new field to a document or documents that are in a collection?

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) {
  var schema = session.getSchema('mySchema');
  var coll = schema.getCollection('myColl');
  var query = "$.name == 'NewField'";
  var newDoc = { name: 'NewField', description: 'a new field', 
                 extra: ['hello', 'world'] …
