Updates to Percona Bug Tracking

Percona Bug Tracking

Percona Bug TrackingWe’re completing our move of Percona bug tracking into JIRA, and the drop-dead date is December 28, 2017.

For some time now, Percona has maintained both the legacy Launchpad bug tracking system and a JIRA bug tracking system for some of the newer products. The time has come to consolidate everything into the JIRA bug tracking system.

Assuming everything goes according to schedule, on December 28, 2017, we will copy all bug reports in Launchpad into the appropriate JIRA projects (with the appropriate issue state). The new JIRA issue will link to the original Launchpad issue, and the new JIRA issue link is added to the original Launchpad issue. Once this is done, we will then turn off editing on the Launchpad projects.

Q&A

Which Launchpad projects are affected?
Why are you copying all closed issues from Launchpad?

Copying all Launchpad issues to JIRA enables it to be the one place to search for previously reported issues, instead of having to search for old issues in Launchpad and new issues in JIRA.

What should I do now to prepare?

Go to https://jira.percona.com/ and create an account.

Thanks for reporting bugs, and post any questions in the comments section.

Percona Monitoring and Management a Trend Setting Product for 2018

DBTA Trend-Setting Products in Data and Information Management for 2018

…but don’t just take our word for it…

Percona Monitoring and Management
DBTA Trend-Setting Products for 2018

The online industry news magazine Database Trends and Applications (DBTA) has included Percona Monitoring and Management in its roundup of Trend-Setting Products in Data and Information Management for 2018.

“…each year, Database Trends and Applications magazine looks for offerings that promise to help organizations derive greater benefit from their data, make better decisions, work more efficiently, achieve greater security, and address emerging challenges.” [December 7, 2018]

As well as including PMM in its selection of products to watch in 2018, DBTA has included a product spotlight penned by Michael Coburn, Product Manager for PMM. This provides a synopsis of the features and benefits of the product for DBAs.

While here at Percona we know that the PMM team are doing excellent work, it’s great they’ve had independent recognition. This news marks a welcome end to a busy and productive year.

The team isn’t resting on its laurels though! We are looking forward to producing further enhancements to PMM throughout 2018.

Watch this space!

Percona Server for MySQL 5.5.58-38.10 is Now Available

percona server 5.5.58-38.10

Percona Server for MySQL 5.5.58-38.10Percona announces the release of Percona Server for MySQL 5.5.58-38.10 on December 7, 2017. Based on MySQL 5.5.58, including all the bug fixes in it, Percona Server for MySQL 5.5.58-38.10 is now the current stable release in the 5.5 series.

Percona Server for MySQL is open-source and free. You can find release details in the 5.5.58-38.10 milestone on Launchpad. Downloads are available here and from the Percona Software Repositories.

New Features:
  • Percona Server packages are now available for Ubuntu 17.10 (Artful).
Bugs Fixed:
  • If an I/O syscall returned an error during the server shutdown with Thread Pool enabled, a mutex could be left locked. Bug fixed #1702330 (Daniel Black).
  • Dynamic row format feature to support BLOB/VARCHAR in MEMORY tables requires all the key columns to come before any BLOB columns. This requirement however was not enforced, allowing creating MEMORY tables in unsupported column configurations, which then crashed or lose data in usage. Bug fixed #1731483.

Other bugs fixed: #1729241.

Find the release notes for Percona Server for MySQL 5.5.58-38.10 in our online documentation. Report bugs on the launchpad bug tracker.

This Week in Data with Colin Charles 17: AWS Re:Invent, a New Book on MySQL Cluster and Another Call Out for Percona Live 2018

Colin Charles

Colin Charles Open Source Database evangelist for PerconaJoin Percona Chief Evangelist Colin Charles as he covers happenings, gives pointers and provides musings on the open source database community.

The CFP for Percona Live Santa Clara 2018 closes December 22, 2017: please consider submitting as soon as possible. We want to make an early announcement of talks, so we’ll definitely do a first pass even before the CFP date closes. Keep in mind the expanded view of what we are after: it’s more than just MySQL and MongoDB. And don’t forget that with one day less, there will be intense competition to fit all the content in.

A new book on MySQL Cluster is out: Pro MySQL NDB Cluster by Jesper Wisborg Krogh and Mikiya Okuno. At 690 pages, it is a weighty tome, and something I fully plan on reading, considering I haven’t played with NDBCLUSTER for quite some time.

Did you know that since MySQL 5.7.17, connection control plugins are included? They help DBAs introduce an increasing delay in server response to clients after a certain number of consecutive failed connection attempts. Read more at the connection control plugins.

While there are a tonne of announcements coming out from the Amazon re:Invent 2017 event, I highly recommend also reading Some data of interest as AWS reinvent 2017 ramps up by James Governor. Telemetry data from sumologic’s 1,500 largest customers suggest that NoSQL database usage has overtaken relational database workloads! Read The State of Modern Applications in the Cloud. Page 8 tells us that MySQL is the #1 database on AWS (I don’t see MariaDB Server being mentioned which is odd; did they lump it in together?), and MySQL, Redis & MongoDB account for 40% of database adoption on AWS. In other news, Andy Jassy also mentions that less than 1.5 months after hitting 40,000 database migrations, they’ve gone past 45,000 over the Thanksgiving holiday last week. Have you started using AWS Database Migration Service?

We have upgraded Grafana and Prometheus in this release. PMM now includes Grafana 4.6.1. One of the most prominent features that the upgraded Grafana offers is the support of annotations.

  • PMM-1549: The authentication of the mongodb:queries monitoring service did not work properly when the name of the database to authenticate was not provided.

This Week in Data with Colin Charles 14: A Meetup in Korea and The Magic Quadrant

Colin Charles

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

We’re close to opening up the call for papers for Percona Live Santa Clara 2018 and I expect this to happen next week. We also have a committee all lined up and ready to vote on submissions.

In other news, I’ve spent some time preparing for the Korean MySQL Power Group meetup to be held in Seoul this Saturday, 11 November 2017. This is a great opportunity for us to extend our reach in Asia. This meetup gathers together top DBAs from Internet companies that use MySQL and related technologies.

Gartner has released their Magic Quadrant for Operational Database Management Systems 2017. Reprint rights have been given to several vendors, e.g. EnterpriseDB and Microsoft. I’m sure you can find other links. The Magic Quadrant features far fewer database vendors now, many have been dropped. What’s your take on it?
