The social events at Percona Live Europe provide the community with more time to catch up with old friends and make new contacts. The formal sessions provided lots of opportunities for exchanging notes, experiences and ideas. Lunches and coffee breaks proved to be busy too. Even so, what’s better than chilling out over a beer or two (we were in Dublin after all) and enjoying the city nightlife in good company?

Percona Live Europe made it easy for us to get together each evening.  A welcome reception (after tutorials) at Sinnott’s Pub in the heart of the City hosted a lively crowd. The Community Dinner at the Mercantile Bar, another lively city center hostelry, was a sell-out. While our closing reception was held at the conference venue, which had proven to be an excellent base. 

Many delegates took the chance to enjoy the best of Dublin’s hospitality late into the night. It’s …

I will be presenting at the ClickHouse MySQL Silicon Valley Meetup on Wednesday, October 25, 2017, at 6:30 PM.

ClickHouse is a real-time analytical database system. Even though they’re only celebrating one year as open source software, it has already proved itself ready for the serious workloads. We will talk about ClickHouse in general, some internals and why it is so fast. ClickHouse works in conjunction with MySQL – traditionally weak for analytical workloads – and this presentation demonstrates how to make the two systems work together.

My talk will cover how we can improve the experience with real-time analytics using ClickHouse, and how we can …

The 2017 MySQL Community Team Award was presented last night at the MySQL Community Reception. As part of this event the MySQL Community Team made a presentation to Alex Rubin of Percona for solving a bug that was report over a dozen years before. The initial bug report was files September 12, 2002 MySQL Does Not Make Toast but Alex demonstrated how to solve the problem in Fixing MySQL Bug#2: now MySQL makes toast! . For this contribution and many years of long, hard work in the MySQL Community, the MySQL Community Team is providing this award to recognize this achievement (and we spent a surprising large percentage of the team budget on this award).

The first release candidate of MySQL 8.0 is here, and I'm happy to share few performance stories about. This article will be about the "most simple" one -- our in-memory Read-Only performance ;-))
However, the used test workload was here for double reasons :

• 1) validate MySQL 8.0 performance
• 2) fully evaluate the "New" Sysbench developed by Alex (https://github.com/akopytov/sysbench)

Going ahead to the second point, the main worry about New Sysbench was about its LUA overhead (the previous version 0.5 was running slower than the old one 0.4 due LUA) -- a long story short, I can confirm now that the New Sysbench is running as fast as the oldest "most lightweight" Sysbench binary I have in use ! so, KUDOS Alex !!! ;-)) …

One of the most exciting features shipped in the Percona Monitoring and Management 1.3.0 (PMM) release is support for MyRocks metrics via a new Metrics Monitor dashboard titled MySQL MyRocks Metrics. The support in PMM follows the recent Percona Server for MySQL release 5.7.19 from September 6, where Percona delivered an EXPERIMENTAL version of MyRocks for non-Production usage.

The MyRocks storage engine from Facebook is based on RocksDB, a persistent key-value store for fast storage environments. MyRocks is optimized for fast storage and combines outstanding space and write efficiency with acceptable read performance. As a result, …

MySQL ShellCLI Interfaces are usually boring, ASCII-ish functional interfaces that are as about as exciting as paint drying or end user license agreements for your rice steamer. They get the job done but no excitement. The new MySQL Shell (mysqlsh instead of mysql at the command line is a great new tool but like its predecessor it is not exactly visually dynamic.

Until Now.

At labs.mysql.com there is a new version of the MySQL Shell that adds some new functionality and some visual enticements. I was in a session at Oracle OpenWorld and was impressed by not only the visually stunning upgrade but by the fact that we now get command auto-completion!

You can login as you did with the old shell but then you see that little bit …
