Galera data on Percona Cloud Tools (and other MySQL monitoring tools)

 | August 29, 2014 |  Posted In: MySQL, Percona Cloud Tools, Percona MySQL Support, Percona XtraDB Cluster, XtraDB Cluster

I was talking with a Percona Support customer earlier this week who was looking for Galera data on Percona Cloud Tools. (Percona Cloud Tools, now in free beta, is a hosted service providing access to query performance insights for all MySQL uses.) The customer mentioned they were already keeping track of some Galera stats on Cacti, and […]

OpenStack Trove Day 2014 Recap: MySQL and DBaaS

 | August 28, 2014 |  Posted In: MySQL, OpenStack, Percona Backup Service, Percona Cloud Tools

I just returned from a week in Cambridge, Massachusetts where I was attending the OpenStack Trove Day and the Trove mid-cycle meetup, both sponsored by the great folks at Tesora. I am relatively new to the OpenStack and Trove arenas so this was a fantastic opportunity for me to learn more about the communities, the […]

Trawling the binlog with FlexCDC and new FlexCDC plugins for MySQL

 | August 27, 2014 |  Posted In: MySQL

Swanhart-Tools includes FlexCDC, a change data capture tool for MySQL. FlexCDC follows a server’s binary log and usually writes “changelogs” that track the changes to tables in the database. I say usually because the latest version of Swanhart-Tools (only in github for now) supports FlexCDC plugins, which allow you to send the updates to a remote […]

mysqld_multi: How to run multiple instances of MySQL

 | August 26, 2014 |  Posted In: Insight for DBAs, MySQL, Percona MySQL Support, Percona Server for MySQL, Percona XtraBackup

The need to have multiple instances of MySQL (the well-known mysqld process) running in the same server concurrently in a transparent way, instead of having them executed in separate containers/virtual machines, is not very common. Yet from time to time the Percona Support team receives a request from a customer to assist in the configuration of […]

OpenStack’s Trove: The benefits of this database as a service (DBaaS)

 | August 25, 2014 |  Posted In: MySQL, OpenStack, Percona Software

In a previous post, my colleague Dimitri Vanoverbeke discussed at a high level the concepts of database as a service (DBaaS), OpenStack and OpenStack’s implementation of a DBaaS, Trove. Today I’d like to delve a bit further into Trove and discuss where it fits in, and who benefits. Just to recap, Trove is OpenStack’s implementation […]

When (and how) to move an InnoDB table outside the shared tablespace

 | August 22, 2014 |  Posted In: InnoDB, Insight for DBAs, MySQL, Percona MySQL Support, Percona Server for MySQL, TokuDB

In my last post, “A closer look at the MySQL ibdata1 disk space issue and big tables,” I looked at the growing ibdata1 problem under the perspective of having big tables residing inside the so-called shared tablespace. In the particular case that motivated that post, we had a customer running out of disk space in his […]

A closer look at the MySQL ibdata1 disk space issue and big tables

 | August 21, 2014 |  Posted In: Benchmarks, InnoDB, Insight for DBAs, MySQL, Percona MySQL Support

A recurring and very common customer issue seen here at the Percona Support team involves how to make the ibdata1 file “shrink” within MySQL. I can only imagine there’s a degree of regret by some of the InnoDB architects on their design decisions regarding disk-space management by the shared tablespace* because this has been a big […]

How to use MySQL Global Transaction IDs (GTIDs) in production

 | August 20, 2014 |  Posted In: Insight for DBAs, MySQL, Percona MySQL Consulting, Technical Webinars

Reconfiguring replication has always been a challenge with MySQL. Each time the replication topology has to be changed, the process is tedious and error-prone because finding the correct binlog position is not straightforward at all. Global Transaction IDs (GTIDs) introduced in MySQL 5.6 aim at solving this annoying issue. The idea is quite simple: each […]
