Compression options in MySQL (part 1) - Percona Database Performance Blog
Over the last year, I have been pursuing a part time hobby project exploring ways to squeeze as much data as possible in MySQL. As you will see, there are quite a few different ways. Of course things like compression ratio matters a lot but, other items like performance of inserts, selects and updates, along with the total amount of bytes written are also important. When you start combining all th

ProxySQL Firewalling
In this blog post, we’ll look at ProxySQL firewalling (how to use ProxySQL as a firewall). Not long ago we had an internal discussion about security, and how to enforce a stricter set of rules to prevent malicious acts and block other undesired queries. ProxySQL came up as a possible tool that could help us in achieving what we were looking for. Last year I wrote about how to use ProxySQL to stop
Internal Temporary Tables in MySQL 5.7
In this blog post, I investigate a case of spiking InnoDB Rows inserted in the absence of a write query, and find internal temporary tables to be the culprit. Recently I was investigating an interesting case for a customer. We could see the regular spikes on a graph depicting “InnoDB rows inserted” metric (jumping from 1K/sec to 6K/sec), however we were not able to correlate those spikes with othe

ZFS from a MySQL perspective
Since the purpose of a database system is to store data, there is close relationship with the filesystem. As MySQL consultants, we always look at the filesystems for performance tuning opportunities. The most common choices in term of filesystems are XFS and EXT4, on Linux it is exceptional to encounter another filesystem. Both XFS and EXT4 have pros and cons but their behaviors are well known and
How to Choose the MySQL innodb_log_file_size
In this blog post, I’ll provide some guidance on how to choose the MySQL innodb_log_file_size. Like many database management systems, MySQL uses logs to achieve data durability (when using the default InnoDB storage engine). This ensures that when a transaction is committed, data is not lost in the event of crash or power loss. MySQL’s InnoDB storage engine uses a fixed size (circular) Redo log sp

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. The first post looked at the elders, the technologies that have been around for more than ten years. The second post talked about the adults, the more recent and mature technologies. In this post, we will look at the emerging MySQL high availability solutions. The “baby” MySQL high availability
MyRocks Experimental Now Available with Percona Server for MySQL 5.7.19-17
Percona, in collaboration with Facebook, is proud to announce the first experimental release of MyRocks in Percona Server for MySQL 5.7, with packages. Back in October of 2016, Peter Zaitsev announced that we were going to port MyRocks from Facebook MySQL to Percona Server for MySQL. Then in April 2017, Vadim Tkachenko announced the availability of experimental builds of Percona Server for MySQL w

will likely fail. That’s the first important limitation of a Galera-based cluster: the size of the number transactions is limited. It is also critical to uniquely identify conflicting rows. The best way to achieve an efficient row comparison is to make sure all the tables have a primary key. In a Galera-based cluster, your tables need primary keys otherwise you’ll run into trouble. That’s the seco
