Announcing: MySQL Fabric 1.6.2 on Labs

The MySQL Fabric team is pleased to announce that a new version is now available on Labs. This labs release includes our latest developments to give you a taste of what we have been working on. In particular, it includes the following new features and improvements:

  • Multi-node Fabric support is now available! This means that multiple fabric nodes can be started and any node can be contacted to perform operations. This allows Fabric itself to be fault-tolerant (no single point of failure) and distribute request across multiple Fabric nodes. For more information, see: Increasing MySQL Fabric Resilience to Failures: Meet the Multi-Node Fabric 
  • Improved security password management, allowing password to not be passed in plain text in the command line or configuration files. …

MySQL Performance: Yes, we can do more than 1.6M QPS (SQL) on MySQL 5.7 GA

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, …

3 Big Announcements from MariaDB (my take for Oct 2015)

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 Versus the Address Sanitizer

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 ' …

State of Percona Server 5.6, MySQL 5.6 and MySQL 5.7 RC

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

MySQL-Docker operations. - Part 1: Getting started with MySQL in Docker

Docker is one of the fastest growing trends in IT. It allows fast deployment of services and applications on a Linux machine (and, with some limits, on other operating systems). Compared to other methods of deploying databases, such as virtual machines or application isolation, it offers faster operations and better performance.
Many people, surprised by the sudden advance of this technology, keep asking What is Docker? And why you should use it?
I will write soon an article with a deep comparison of the three methods (VM, container, sandbox), but for now, we should be satisfied with a few basic facts:

  • Docker is a Linux container. It deploys every application as a series of binary …
