Two weeks after the big annual event in San Francisco, Oracle Open World 2016 , September 18-22, there will be another MySQL focused event in Europe: Percona Live Amsterdam, October 3-5.

The MySQL Engineering Team and Community Team will be present. We have submitted a list of very interesting talks, mostly related to the upcoming new major release of MySQL.

In an effort to involve the larger community in the talks selections, PLAM’s organization implemented a community voting process for the previous edition. If this will be again the case and if you are interested by our sessions, don’t hesitate to vote, if the vote is available, for the sessions you would like to see or just tweet about them using #perconalive …

From September 18–22, 2016 in San Francisco will be held the 2016’s edition of Oracle Open World. The MySQL Team will be well represented with more than 20 sessions related to all the new stuff we released for 5.7 and many other amazing things for 8.0.

I have the honor to present you a tutorial on one of the most wanted feature: Group Replication.

MySQL Group Replication is a new plugin that ensures virtual synchronous updates on any member in a group of MySQL servers, with conflict handling and failure detection. Distributed recovery is also in the package to ease the process of adding new servers to your server group.

This tutorial will be full hands-on. Matt Lord and myself will guide on the process of upgrading your asynchronous replication architecture to the new multi-master group replication !

This is the link to our tutorial: …

Most people know that you can use SHOW SLAVE STATUS to verify if a slave is running in MySQL. Most people also know that you need to check both Slave_IO_Running and Slave_SQL_Running.

View the code on Gist.

A few years ago, I responded to a question on dba.stackexchange.com on how to verify if a slave is running outside of SHOW SLAVE STATUS.

Prior to MySQL 5.7, you could get this information from SHOW GLOBAL STATUS:

The MariaDB project is pleased to announce the immediate availability of MariaDB 10.1.16. See the release notes and changelog for details on this release. Download MariaDB 10.1.16 Release Notes Changelog What is MariaDB 10.1? MariaDB APT and YUM Repository Configuration Generator Thanks, and enjoy MariaDB!

The post MariaDB 10.1.16 now available appeared first on MariaDB.org.

In a previous post, I presented an Unexpected Memory Consumption for Bulk Index Creation in InnoDB.  This was triggered by an increased innodb_sort_buffer_size and as stated in another post: "the sorting algorithm does not scale well with large sort buffers".  In this post, I will present why it does not scale well and I will suggest solutions.

This post also answers feedback request for the

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 …

This topic is about general usage for MySQL Shell and X-Plugin.
The most important thing, i think we should keep in mind that, the X-Plugin will listen not MySQL’s port, but it’s own 33060 port as shown from log:

2016-07-15T07:21:09.454761Z 200 [Note] Plugin mysqlx reported: 'X plugin tcp connection enable at port 33060.'
2016-07-15T07:21:09.454959Z 200 [Note] Plugin mysqlx reported: 'Scheduler "work" started.'
2016-07-15T07:21:09.454976Z 200 [Note] Plugin mysqlx reported: 'X plugin initialization successes'
2016-07-15T07:21:09.484303Z 201 [Note] Plugin mysqlx reported: 'Using existing mysqlxsys@localhost account for authentication. Incomplete grants will be fixed'
2016-07-15T07:21:09.501627Z 0 [Note] Plugin mysqlx reported: 'Using OpenSSL for TCP connections'
2016-07-15T07:21:09.501752Z 0 [Note] Plugin mysqlx reported: 'Server starts handling incoming connections'

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.
