In this blog post we’ll discuss a caveat when downloading MariaDB MaxScale binaries.

Following the previous performance results in my last two posts on sysbench and primary keys (https://www.percona.com/blog/2016/04/07/mysql-5-7-sysbench-oltp-read-results-really-faster/ and https://www.percona.com/blog/2016/03/28/mysql-5-7-primary-key-lookup-results-is-it-really-faster/), I wanted to measure overhead from proxies servers like ProxySQL and MaxScale.

Unfortunately, I found that MaxScale binaries are not available without registering on the …

MySQL 5.7.12 is the fourth stable (GA) release of the MySQL 5.7 series. It brings with it the usual bug fixes and incremental enhancements that you would expect with a point release. Except this time things are a little bit different.…

Time flies, and my blogging frequency is quite low. More frequent would be better, but knowing myself I'll rather not promise anything ;-)

Still, it is appropriate to write some notes about CeBIT, the "Chemnitzer Linuxtage 2016", and future events.

CeBIT

CeBIT was running from March 14 to 18 (Monday till Friday) in Hannover, Germany, and I will leave the general assessment to the various marketing departments as well as to the regular visitors (to which I do not belong).

In order to meet our current customers as well as potential future ones, FromDual had a booth in the "Open Source Forum". We displayed a Galera Cluster, running on three tiny headless single-board Linux machines, and showed how it reacts to node failures and then recovers all by itself, without any administrator intervention. Many of our visitors were fascinated, because a HA solution would be a …

Network Throttling tool provided by Google Chrome Developer tools
In this video we will be seeing how this tool helps us to test your application at different network speeds, thus giving us info and insight as to how users having different speeds of internet use our application and the challenges they face and how the performance can be improved and how the application can be made more usable in such cases.

In this blog, we will examine the differences between GCache and Record-Set Cache in Percona XtraDB Cluster.

In Percona XtraDB Cluster (PXC), there is the concept of GCache and Record-Set cache (which can also be called transaction write-set cache). The use of these two caches is often confusing if you are running long transactions, as both of them result in the creation of disk-level files. Let’s understand what their main differences are.

Record-Set Cache

• When you run a long-running transaction on any particular node, it will try to append a key for each row that it tries to modify (the key is a unique identifier for the row {db,table,pk.columns}). This information is cached in out-write-set, which is then sent to the group for …

In this blog, we’ll discuss how the Percona XtraDB Cluster threading model works.

Percona XtraDB Cluster (PXC) creates a different set of threads to service its operations. These threads are in addition to existing MySQL threads. Let’s understand what these threads are and how they’re used. There are three main groups of threads:

1. Applier thread(s)
   1. Applier threads are meant to apply write-sets that the node receives from other nodes (through cluster). (write-message is directed through

      gcv_recv_thread

      .)
   2. The number of applier threads is controlled using the

      wsrep_slave_thread

       configuration. (The default value is 1, so at least one wsrep applier thread …
