Fixed Bugs

  • Added access checks for DDL commands to make sure they do not get replicated if they failed without proper permissions. Previously, when a user tried to perform certain DDL actions that failed locally due to lack of privileges, the command could still be replicated to other nodes, because access checks were performed after replication.This vulnerability is identified as CVE-2017-15365.

This week was exciting from a Percona exposure standpoint. We were at Open Source Summit Europe. I gave two talks and participated in a panel, as the co-located event for the Open Source Entrepreneur Network happened on the last day as well. We had a booth, and it was great to hang out and talk with my colleagues Dorothée Wuest and Dimitri Vanoverbeke as well as all the attendees that popped by.

Percona Monitoring and Management 1.4.0 Is Now Available

Percona Monitoring and ManagementPercona announces the release of Percona Monitoring and Management 1.4.0.

This release introduces the support of external Prometheus exporters so that you can create dashboards in the Metrics monitor even for the monitoring services other than those provided with PMM client packages. To attach an existing external Prometheus exporter, run pmm-admin add external:metrics NAME_OF_EXPORTER URL:PORT.

The list of attached monitoring services is now available not only in the tabular format but also as a JSON file to enable automatic verification of your configuration. To view the list of monitoring services in the JSON format run pmm-admin list --json.

In this release, Prometheus and Grafana have been upgraded. Prometheus version 1.7.2, shipped with this release, offers a number of bug fixes that will contribute to its smooth operation inside PMM. For more information, see the Prometheus change log.

Version 4.5.2 of Grafana, included in this release of PMM, offers a number of new tools that will facilitate data analysis in PMM:

  • New query editor for Prometheus expressions features syntax highlighting and autocompletion for metrics, functions and range vectors.
    Percona Monitoring and Management
  • Query inspector provides detailed information about the query. The primary goal of graph inspector is to enable analyzing a graph which does not display data as expected.
    Percona Monitoring and Management

The complete list of new features in Graphana 4.5.0 is available from What’s New in Grafana v4.5.

For install and upgrade instructions, see Deploying Percona Monitoring and Management.

New features

  • PMM-1520: Prometheus upgraded to version 1.7.2.
  • PMM-1521: Grafana upgraded to version 4.5.2.
  • PMM-1091: The pmm-admin list produces a JSON document as output if the --json option is supplied.
  • PMM-507: External exporters are supported with pmm-admin.
  • PMM-1622: docker images of PMM Server are available for downloading as tar packages.

Improvements

  • PMM-1553: Consul upgraded to the 0.8 release.

Bug fixes

  • PMM-1172: In some cases, the TABLES section of a query in QAN could contain no data and display the List of tables is empty error. The Query and Explain sections had the relevant values.
  • PMM-1519: A Prometheus instance could be forced to shut down if it contained too many targets (more than 50). When started the next time, Prometheus initiated a time-consuming crash recovery routine which took long on large installations.

This Week in Data with Colin Charles 9: Oracle OpenWorld and Percona Live Europe Post Mortem

Colin Charles

Colin CharlesJoin Percona Chief Evangelist Colin Charles as he covers happenings, gives pointers and provides musings on the open source database community.

This week: a quick roundup of releases, a summary of my thoughts about Percona Live Europe 2017 Dublin, links to look at and upcoming appearances. Oracle OpenWorld happened in San Francisco this past week, and there were lots of MySQL talks there as well (and a good community reception). I have a bit on that as well (from afar).

Look for these updates on Planet MySQL.

Releases

Percona Live Europe 2017Percona Live Europe Dublin

I arrived on Sunday and chose to rest for my tutorial on Monday. Ronald Bradford and I delivered a tutorial on MySQL Security, and in the morning we chose to rehearse. Percona Live Europe had a full tutorial schedule this year, albeit with one cancellation: MySQL and Docker by Giuseppe Maxia, whom we missed this conference. Check out his blog for further posts about MySQL, Docker, and SQL Roles in MySQL 8!

We had the welcome reception at Sinott’s Bar. There was a large selection of food on each table, as well as two drinks for each of us. It was lively, and I think we overtook most of the basement. Later that evening, there were drinks around the hotel bar, as people started to stream in for Tuesday’s packed schedule!

Tuesday was the conference kickoff, with Peter Zaitsev doing the opening keynote on the state of the open source database ecosystem. The bonus of this keynote was also the short 5-minute talks that would help you get a pick on the important topics and themes around the conference. I heard good things about this from attendees. While most people attended the talks, I spent most of my day in meetings! Then the Community Dinner (thank you Oracle for sponsoring), where we held this year’s Lightning Talks (and plenty more to drink). A summary of the social events is at Percona Live Europe Social.

Wednesday morning we definitely wanted to start a few minutes later, considering people were streaming in slower thanks to the poor weather (yes, it rained all day). The State of the Dolphin ensured we found out lots of new things coming to MySQL 8.0 (exciting!), then the sponsor keynote by Continuent given by MC Brown, followed by a database reliability engineering panel with the authors of Database Reliability Engineering Charity Majors and Laine Campbell. Their book signing went quickly too – they have many fans. We also heard from Pepper Media on their happy journey with Percona. Another great day of talks before the evening reception (which had less folk, since people were flying off that evening). Feel free to also read Matthias Crauwels, Percona Live Europe 2017 Review.

Percona Live Europe 2017 Dublin had over 350+ attendees, over 140+ speakers – all in a new location! If you have any comments please feel free to shoot me an email.

Oracle Open WorldOracle OpenWorld from Afar

At this year’s Oracle OpenWorld there was talk about Oracle’s new self-driving, machine-learning based autonomous database. There was a focus on Amazon SLAs.

It’s unclear if this will also be what MySQL gets eventually, but we have in the MySQL world lossless semi-sync replication. Amazon RDS for MySQL is still DRBD based, and Google Cloud SQL does use semisync – but we need to check further if this is lossless semisync or not.

Folk like Panoply.io claim they can do autonomous self-driving databases, and have many platform integrations to boot. Anyone using this?

Nice to see a Percona contribution to remove InnoDB buffer pool mutex get accepted, and apparently it was done the right way. This is sustainable engineering: fix and contribute back upstream!

I was particularly interested in StorageTapper released by Uber to do real-time MySQL change data streaming and transformation. The slide deck is worth a read as well.

Booking.com also gave a talk. My real takeaway from this was about why MySQL is strong: “thousands of instances, a handful of DBAs.” Doug Henschen also talks about a lot of custom automation capabilities, the bonus of which is many are probably already open source. There are some good talks and slide decks to review.

It wouldn’t be complete without Dimitri Kravtchuk doing some performance smackdowns, and I highly recommend you read MySQL Performance: 2.1M QPS on 8.0-rc.

And for a little bit of fun: there was also an award given to Alexander Rubin for fixing MySQL#2: does not make toast. It’s quite common for open source projects to have such bugs, like the famous Ubuntu bug #1. I’ve seen Alexander demo this before, and if you want to read more check out his blog post from over a year ago: Fixing MySQL Bug#2: now MySQL makes toast! (Yes, it says April 1! but really, it was done!) Most recently it was done at Percona Live Santa Clara 2017.

Pepper Turns to Percona to Ensure a Great Customer Experience at Pepper.com

Pepper.com

Pepper.comPepper.com, the world’s largest community deal platform, has selected Percona to manage its open source database performance.

Pepper.com’s around-the-clock community seeks and finds the best offers in fashion, electronics, traveling and much more. With 500 million page views, over 25 million users and over 65,000 user-submitted deals per month across communities in America, Europe and Asia, Pepper has quickly risen to be the largest community deal platform worldwide.

When Pepper.com’s primary MySQL database administrator left the company, Pepper decided to shift to a managed service to maintain uptime and responsiveness. Having previously attended Percona Live Europe, the premier European open source database conference, as well as being avid readers of the Percona Database Performance Blog, the Pepper team turned to Percona for open source database remote managed service expertise.

“Guaranteeing database performance is key to making sure our web applications are responsive and up-to-date,” said Pavel Genov, Head of Software Development at Pepper.com. “Percona Care Ultimate helps us to achieve these objectives.”

Pepper.comPepper was already using Percona Server for MySQL. Following a Percona Database Performance Audit to review the Pepper.com environment, architecture and setup, Percona XtraBackup was deployed to provide online non-blocking, tightly compressed, highly secure backups.

Check out the case study on Pepper.com and Percona’s engagement to improve and manage Pepper’s database environment.
