Let’s answer a question which, to my knowledge, has never been systematically addressed: What are the requirements for a production-ready query metrics app at scale? I am uniquely qualified to answer that because I have written four query metrics apps, two of which are the open-source standard for MySQL: pt-query-digest and the original (v1) code behind the query metrics/analysis part of Percona Monitoring and Management. I’ve also published a couple of packages related to query metrics: go-mysql/slowlog and go-mysql/query.

Galera replication technology, a key component of Percona XtraDB Cluster, suffered from a remote code execution vulnerability. Percona has been working with the vendor since early September on this issue and has made releases available to address the problem.

Applicability

A malicious party with access to the WSREP service port (4567/TCP) as well as prerequisite knowledge of the configuration of the Galera cluster name is required in order to exploit this vulnerability, which leads to remote code execution via the WSREP protocol. 

Fixes are available in Percona XtraDB Cluster versions:

MySQL 8.0.22 was released roughly a week ago. It includes some nice additions to replication that we would like to call out. Here they are:

• Automatic Asynchronous Replication Connection Failover (WL#12649). This work, by Hemant Dangi, implements a mechanism in asynchronous replication that makes the replica automatically try to re-establish an asynchronous replication connection to another replication source, in case the current connection gets interrupted;
• New terminology for replica related statements (WL#14171).

Software development is always moving forward, and the latest version is always the best ... until the next one arrives.  When you visit the MySQL Ndb Cluster downloads page, you are naturally recommended to pull the latest MySQL Cluster 8.0.22 (announcement), but sometimes it is good to look back at the journey taken to reach this point.

7.x release series

Prior to the 8.0 releases, MySQL Ndb Cluster had a sequence of 7.x (x=0..6) releases based on MySQL Server versions 5.1, 5.6, 5.7.  In each of the 7.x release series, MySQL Ndb Cluster was under feature development for some time, producing a number of minor releases, until eventually one minor release was validated as being acceptable as the first generally available (GA) …

Google Cloud SQL for MySQL is a fully-managed database service that helps you set up, maintain, manage, and administer your MySQL relational databases on Google Cloud Platform. However, there are differences between Cloud SQL and standard MySQL functionality like limited control, restricted resources, data locality, budget and security, which may influence your final decision to move out from the Google Cloud SQL instances and host the database service in the on-premises infrastructure instead.

This blog post will walk you through how to perform online migration from Google Cloud SQL to an on-premises server. Our target database on the on-premises server is a Debian server, but the steps and procedures shall apply on other versions of Linux as well as long as packages are …
