It was exactly 2 years now since we reached 500K QPS with MySQL 5.7 -- it was a great milestone, and the highest ever result seen on MySQL with true SQL queries ;-)) And this was on 32cores-HT machine.. (the linked article contains the whole long story how we arrived to 250K QPS first, then 275K, 350K, 440K, and finally 500K QPS) -- the main improvement here is coming from greatly redesigned transactions and transaction list management in MySQL 5.7.

However, when the 40cores-HT server arrived to MySQL LAB we were not yet ready to show more than 500K QPS -- there were still some other contentions on external to InnoDB level.. Once these all were fixed, we finally reached 645K QPS on 40cores-HT server and pushed the limit more far yet ;-) -- this is what we were able to announce a year ago, …

Redundancy is key to providing resilience to failures, and in Fabric 1.6.2 (now available on MySQL Labs), we have introduced the possibility to start multiple MySQL Fabric instances that are kept consistent through a replicated state machine.

Today I received about five emails with the subject: 3 Big Announcements from MariaDB. Maybe you did as well (else, read it online). October has brought on some very interest announcements, and I think my priority for the big announcements vary a little:

1. MariaDB Server is now available on Amazon RDS – you wouldn’t believe how many people ask for this, as many now deploy using Amazon …

MySQL 5.7 supports the Address Sanitizer, which checks for several memory related software errors including memory leaks.  It is really nice to see support for the Address Sanitizer built into MySQL.  Unfortunately, when running the mysql tests included in MySQL 5.7.9, the Address Sanitizer reports several memory leaks, which causes some of  the tests to fail.  Here are some of the memory leaks in the MySQL 5.7.9 software found by the Address Sanitizer.
Memory leaks in 'mysqlbinlog'Several of the 'mysqlbinlog' tests fail due to memory leaks in the 'mysqlbinlog' client program.  Here are the details from the ' …

This week Oracle will release MySQL 5.7 GA, so it’s a perfect time to do a quick review of the current state of Percona Server 5.6.26, MySQL 5.6.26 and MySQL-5.7.8 RC. We used two boxes from our benchmark lab for this:
– Box 1: 16 Cores+HT (32 virt cores)/fast PCIe ssd card/RAM: 192GB
– Box 2: 24 Cores+HT(48 virt cores)/fast PCIe ssd card/RAM: 128GB

Dataset: sysbench/uniform, 32 tables with 12M rows each, ~95GB
Tests: sysbench – point select, oltp read only, oltp read/write
Test sequence: start server, warmup, series of the tests (each lasts 5 minutes) from 1 to 4096 threads

Tests were run for two setups:
– CPU bound (in memory) – innodb_buffer_pool_size=100GB
– IO bound – innodb_buffer_pool_size=25GB

Requires ClusterControl 1.2.11 or later. Applies to MySQL based clusters.

In this example we will look at how you can use ClusterControl to create a user and assign privileges to the user. We will create a user that has enough privileges to perform an xtrabackup.

In the ClusterControl UI press Manage > Schemas and Users, and then press Create Account. You will see the following screen, and here we have filled out the details to create a user with enough privileges to run xtrabackup:

Server refers to the server from which the user is allowed to connect. In Create On DB Node you can select a particular server to …
