We would like to remind that you can find MySQL at OpenSource Day, Poland in Warsaw next Tuesday, May 14. Please find details below:

• Name: OpenSource Day
• Date: Tue, May 14, 2019
• Place: Warsaw, Poland
• MySQL Session: "MySQL InnoDB Cluster: High Availability with no stress!" given by Vittorio Cioe, the MySQL Senior Sales Consultant

This year we are sharing our resources with our friends from Oracle Linux team. You can find the Linux session just after MySQL one in the online agenda. We are also going to share the booth in expo area, so if you have any queries for either MySQL or Linux products, do not hesitate to come to talk to us to our booth in expo area! We are looking forward to talking to you in Warsaw!

Master has purged binary logs containing GTIDs that the slave requires Problem :  Last_IO_Error: Got fatal error 1236 from master when reading data from binary log: 'The slave is connecting using CHANGE MASTER TO MASTER_AUTO_POSITION = 1, but the master has purged binary logs containing GTIDs that the slave requires.'

Solution : stop slave;
Query OK, 0 rows affected (0.00 sec)

CHANGE MASTER TO MASTER_AUTO_POSITION = 0;
Query OK, 0 rows affected (0.01 sec)

start slave;
Query OK, 0 rows affected (0.00 sec)

At the end of the month, some engineers of the MySQL Team will be present in Austin, TX !

We will attend the first edition of Percona Live USA in Texas.

During that show, you will have the chance to meet key engineers, product managers, as well as Dave and myself.

Let me present you the Team that will be present during the conference:

The week will start with the MySQL InnoDB Cluster full day tutorial by Kenny and myself. This tutorial is a full hands-on tutorial where we will start by migrating a classical asynchronous master-replicas topology to a new MySQL InnoDB Cluster. We will then experience …

Overview The Skinny

From time to time we are asked how to check whether or not there are data discrepancies between Master/Slave nodes within a MySQL (or MariaDB) cluster that’s managed with Tungsten Clustering. This is always a challenging task, not least because we hope and believe that our replication mechanism would avoid such occurrences, that said there can be factors outside of our control that can appear to “corrupt” data – such as inadvertent execution of DML against a slave using a root level user account.

Tungsten Replicator, the core replication component in our Tungsten Clustering solution for MySQL (& MariaDB), is just that, a replicator – it takes transactions from the binary logs and replicates them around. The replicator isn’t a data synchronisation tool in that respect, the …

Percona is glad to announce the release of Percona XtraBackup 8.0.6 on May 9, 2019. You can download it from our download site and apt and yum repositories.

Percona XtraBackup enables MySQL backups without blocking user queries, making it ideal for companies with large data sets and mission-critical applications that cannot tolerate long periods of downtime. Offered free as an open source solution, it …

In my previous post Running MySQL/Percona Server in Kubernetes with a Custom Config I’ve looked at how to set up MySQL in Kubernetes to utilize system resources fully. Today I want to measure if there is any performance overhead of running MySQL in Kubernetes, and show what challenges I faced trying to measure it.

I will use a very simple CPU bound benchmark to measure MySQL performance in OLTP read-only workload:

sysbench oltp_read_only --report-interval=1 --time=1800 --threads=56 --tables=10 --table-size=10000000 --mysql-user=sbtest --mysql-password=sbtest --mysql-socket=/var/lib/mysql/mysql.sock run

The hardware is as follows:

Supermicro server

• Intel(R) Xeon(R) CPU E5-2683 v3 @ 2.00GHz
• 2 sockets / 28 cores / 56 threads
• Memory: 256GB of …

Many products use OpenSSL, but for the most part, without choosing to incorporate the OpenSSL FIPS (US Federal Information Processing Standards) module. However it may be that running OpenSSL and using FIPs mode is something you should seriously consider and implement.…
