At AWS Re:Invent 2018 there were many great announcements of AWS New Services and New Features, but one basic feature that I’ve been waiting for years to be released is still nowhere to be found.
AWS Elastic Block Storage (EBS) is great and it’s got better through the years, adding different storage types and features like Provisioned […]
Starting with PMM 1.13, PMM uses Prometheus 2 for metrics storage, which tends to be heaviest resource consumer of CPU and RAM. With Prometheus 2 Performance Improvements, PMM can scale to more than 1000 monitored nodes per instance in default configuration. In this blog post we will look into PMM scaling and capacity planning—how […]

Is increasing GP2 volumes size or increasing IOPS for IO1 volumes a valid method for scaling IO-Bound workloads? In this post I’ll focus on one question: how much can we improve performance if we use faster cloud volumes? This post is a continuance of previous cloud research posts:

If you are a regular reader of this blog, you likely know I like the ZFS filesystem a lot. ZFS has many very interesting features, but I am a bit tired of hearing negative statements on ZFS performance. It feels a bit like people are telling me “Why do you use InnoDB? I have […]

The ability to restore MySQL logical backups is a significant part of disaster recovery procedures. It’s a last line of defense.
Even if you lost all data from a production server, physical backups (data files snapshot created with an offline copy or with Percona XtraBackup) could show the same internal database structure corruption as in […]
In this blog post, I will talk about archiving MySQL tables in ClickHouse for storage and analytics.
Why Archive?
Hard drives are cheap nowadays, but storing lots of data in MySQL is not practical and can cause all sorts of performance bottlenecks. To name just a few issues:
The larger the table and index, the slower the performance […]

While preparing a post on the design of ZFS based servers for use with MySQL, I stumbled on the topic of fsync call performance. The fsync call is very expensive, but it is essential to databases as it allows for durability (the “D” of the ACID acronym).
Let’s first review the type of disk IO operations […]

In this webinar, Colin uses a ticket sales website that does “normal” events like an M2M concert, but also occasionally also sells tickets to the Harry […]
This post is a hands-on look at ZFS with MySQL.
In my previous post, I highlighted the similarities between MySQL and ZFS. Before going any further, I’d like you to be able to play and experiment with ZFS. This post shows you how to configure ZFS with MySQL in a minimalistic way on either Ubuntu […]
