Making Maxscale/ProxySQL Highly Available ( 2 > 1 )

As Mydbops we are implementing Load Balancer using Maxscale or ProxySQL ( Our presentation ) for lot our client,  but these load balancers will become a SPOF (Single Point of failure) .  We have tried to explore services like HAProxy, Nginx, and Keepalived etc. Except Keepalived, all the services need to run on the standalone instance and  did not satisfy our exact need.

Keepalived does not requires any standalone instance, it can be deployed and configured with a minimal effort and provide the HA Solutions to the DB Infra. This approach not only fits for our DB setup, we can implement same …

The State of MySQL High Availability Going in to 2018

High availability for MySQL has become increasingly relevant given the ever increasing rate of adoption and implementation. It’s no secret to anyone in the community that the popularity of MySQL has become noteworthy. I still remember my start with MySQL in the early 5.0 days and people told me that I may not want to consider wasting my time training on a database that didn’t have a large industry adoption, but look at where we are now! One of my favorite pages to cite when trying to exhibit this fact is the db-engines.com ranking trend page where we can see that MySQL is right up there and contending with enterprise products such as Microsoft SQL Server and Oracle.

MySQL has gone from being part of the ever famous LAMP stack for users looking to set up their first website to seeing adoption from major technical players such as …

The MySQL High Availability Landscape in 2017 (the Babies)

This post is the third of a series focusing on the MySQL high availability solutions available in 2017.

In this post, we will look at the emerging MySQL high availability solutions. The “baby” MySQL high availability solutions I chose for the blog are group replication, proxies and distributed storage.

MySQL Support Engineer's Chronicles, Issue #6

Previous post in series was published almost 4 months ago, but I do not plan to end it. So, let me quickly discuss some of problems I worked on or was interested in so far in June, and provide some useful links.

Back on June 2 I had to find out what exact files are created by MariaDB's ColumnStore when I create a table in this storage engine. Actually in recent versions one can check the tables in the INFORMATION_SCHEMA, but if still wonders why are all these directories with numbers in the names (/usr/local/mariadb/columnstore/data1/000.dir/000.dir/011.dir/193.dir/000.dir/FILE000.cdf), please, check also this …

MySQL Support Engineer's Chronicles, Issue #5

A lot of time passed since my previous post in this series. I was busy with work, participating in FOSDEM, blogging about profilers and sharing various lists of MySQL bugs. But I do not plan to stop writing about my usual weeks of doing support engineer's job. So, time for the next post in this series, based on my random notes taken during the week here and there.

This week started for me with checking recent MySQL bug reports (actually I do it every day). …

MySQL Support Engineer's Chronicles, Issue #4

This week I had to deal with some unusual problems. But let me start with Percona's xtrabackup, software that I consider a key component of many current production MySQL setups and use regularly. Recently new minor versions of XtraBackup were released, check the details on 2.4.5, for example. It made a step towards support of MariaDB 10.2, but it's still a long way to go, see this pull request #200.

My main problem with xtrabackup, though, is not with lack of support of MariaDB 10,2-specific features. Why should they care, after all... The problem is that old well known bugs and problems are not resolved, those that may affect all MySQL versions, forks and environments. Check  …
