This Week in Data with Colin Charles 20: cPanel changes strategy, Percona Live CFP extended

Colin Charles

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

I think the biggest news from last week was from cPanel – if you haven’t already read the post, please do – on Being a Good Open Source Community Member: Why we hesitated on MySQL 5.7. cPanel anticipated MariaDB being the eventual replacement for MySQL, based on movements from Red Hat, Wikipedia and Google. The advantage focused on transparency around security disclosure, and the added features/improvements. Today though, “MySQL now consistently matches or outpaces MariaDB when it comes to development and releases, which in turn is increasing the demand on us for providing those upgraded versions of MySQL by our users.” And maybe a little more telling, “when MariaDB 10.2 became stable in May 2017 it included many features found in MySQL 5.7. However, MySQL reached stable nearly 18 months earlier in October 2015.” (emphasis mine).

So cPanel is going forth and supporting MySQL 5.7. They will continue supporting MariaDB Server for the foreseeable future. This really is cPanel ensuring they are responsive to users: “The people using and building database-driven applications are doing so with MySQL in mind, and are hesitant to add support for MariaDB. Responding to our community’s desires is one of the most important things to us, and this is something that we are hearing asked for from our community consistently.”

I, of course, think this is a great move. Users deserve choice. And MySQL has features that are sometimes still not included in MariaDB Server. Have you seen the Complete list of new features in MySQL 5.7? Or my high-level response to a MariaDB Corporation white paper?

I can only hope to see more people think pragmatically like cPanel. Ubuntu as a Linux distribution still does – you get MySQL 5.7 as a default (very unlike the upstream Debian which ships MariaDB Server nowadays). I used to be a proponent of MariaDB Server being everywhere, when it was community-developed, feature-enhanced, and backward-compatible. However, the moment it stopped being a branch and a true fork is the moment where trouble lies for users. I think it was still marginally fine with 10.0, and maybe even 10.1, but the ability to maintain feature parity with enhanced features has long gone. Short of a rebase? But then… what would be different to the already popular branch of MySQL called Percona Server for MySQL?

While there are wins and support from cloud vendors, like Amazon AWS RDS and Microsoft Azure, you’ll notice that they offer both MySQL and MariaDB Server. Google Cloud SQL notably only offers MySQL. IBM may be a sponsor of the MariaDB Foundation, but I don’t see their services like Compose offering anything other than MySQL (with group replication nonetheless!). Platinum member Alibaba Cloud offers MySQL and PostgreSQL. However, Tencent seems to suggest that MariaDB is coming soon? One interesting statistic to watch would be user uptake naturally.

Events

From an events standpoint, the Percona Live 2018 Call for Papers has been extended to January 12, 2018. We expect an early announcement of maybe ten talks in the week of  January 5. Please submit to the CFP. Have you got your tickets yet? Nab them during our Percona Live 2018 super saver registration when they are the best price!

FOSDEM has got Sveta and myself speaking in the MySQL and Friends DevRoom, but we also have good news in the sense that Peter Zaitsev is also going to be at FOSDEM – speaking in the main track. We’ll also have plenty of schwag at the stand.

I think it’s important to take note of the updates to Percona bug tracking: yes, its Jira all the way. Would be good for everyone to start also looking at how the sausage is made.

Dragph, a “distributed fast graph database“, just raised $3m and released 1.0. Have you used it?

On a lighter note, there seems to be a tweet going around by many, so I thought I’d share it here. Merry Christmas and Happy Holidays.

Percona Live 2018 Call for Papers Deadline Extended to January 12, 2018

Percona Live 2018 Call for Papers

Percona Live 2018 Call for PapersPercona is extending the Percona Live 2018 call for papers deadline to January 12, 2018!

Percona’s gift to you this holiday season is the gift of time – submit your speaking topics right up until January 12, 2018!

As the year winds up, we received many requests to extend the Percona Live Open Source Database Conference 2018 call for papers. Since many speakers wanted to submit during the week that they’re planning vacations (from Christmas until New Year’s Day), we realized that December 22 was too soon.

If you haven’t submitted already, please consider doing so. Speaking at Percona Live is a great way to talk about what you’re doing, build up your personal and company brands, and get collaborators to your project. If selected, all speakers receive a full complimentary conference pass.

Percona Live 2018 is the destination to share, learn and explore all pertinent topics related to open source databases. The theme for Percona Live 2018 is “Championing Open Source Databases,” with topics on MySQLMongoDB and other open source databases, including time series databases, PostgreSQL and RocksDB. Session tracks include Developers, Operations, and Business/Case Studies.

Percona Live KeynotesRemember, just like last year, we aren’t looking for just MySQL-ecosystemrelated talks (that includes MariaDB Server and Percona Server for MySQL). We are actively looking for talks around MongoDB, as well as other open source databases (so this is where you can add PostgreSQL, time series databases, graph databases, etc.). That also involves complementary technologies, such as the increasing importance of the cloud and container solutions such as Kubernetes.

Talk about your journey to open source. Describe the technical and business values of moving to or using open source databases. How did you convince your company to make the move? Was there tangible ROI? Share your case studies, best practices and technical knowledge with an engaged audience of open source peers.

We are looking for breakout sessions (25 or 50 minutes long), tutorials (3 hours or 6 hours long), and lightning talks and birds of a feather sessions. Submit as many topics as you think you can deliver well.

The conference itself features one day of tutorials and two days of talks. There will also be exciting keynote talks. Don’t forget that registration is now open, and our Super Saver tickets are the best price you can get (Super Saver tickets are on sale until January 7, 2018).

If your company is interested in sponsoring the conference, please take a look at the sponsorship prospectus.

All in, submit away and remember the Percona Live 2018 call for papers deadline is January 12, 2018. We look forward to seeing you at the conference from April 23-25 2018 in Santa Clara.

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?

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

Hurry up – the call for papers (CFP) for FOSDEM 2018 ends December 1, 2017. I highly recommend submitting as its a really fun, free, and technically-oriented event.

Don’t forget that the CFP for Percona Live Open Source Database Conference 2018 in Santa Clara closes December 22, 2017, so please also consider submitting as soon as possible. We want to make an early announcement of the talks, so we’ll definitely do the first pass even before the CFP date closes.

Is ARM the new hotness? Marvell confirms $6 billion purchase of chip maker Cavium. This month we’ve seen Red Hat Enterprise Linux for ARM arrive. We’ve also seen a press release from MariaDB about the performance on the Qualcomm Centriq 2400 Processor.

Some new books to add to your bookshelf and read: MariaDB and MySQL Common Table Expressions and Window Functions Revealed by Daniel Bartholomew. The accompanying source code repository will also be useful. Much awaited for, by Percona Live keynote speakers, Database Reliability Engineering: Designing and Operating Resilient Database Systems by Laine Campbell and Charity Majors is now ready to read.

This Week in Data with Colin Charles 15: Percona Live 2018 Call for Papers and Best Practices for Observability

Colin Charles

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

So we have announced the call for presentations for Percona Live Santa Clara 2018. Please send your submissions in!

As you probably already know, we have been expanding the content to be more than just MySQL and MongoDB. It really does include more open source databases: the whole of 2016 had a “time series” theme to it, and we of course love to have more PostgreSQL content (there have been tracks dedicated to PostgreSQL for sometime now). I found this one comment interesting recently, from John Arundel, “If you’re going to learn one database really well, make it Postgres.” I have been noticing newer developers jump on the PostgreSQL bandwagon. I presume much of this blog’s readership is still MySQL centric, but it will be interesting to see where this goes.

Charity Majors recently wrote Best Practices for Observability. In addition, her book alongside Laine Campbell is now available for purchase on Kindle: Database Reliability Engineering: Designing and Operating Resilient Database Systems. Highly recommended purchase. You can also get it on O’Reilly Safari (free month with those codes for Percona Live Europe Dublin attendees).

Are you using Google Cloud Spanner? It now has multi-region support, and has an updated SLA for 99.999% uptime. That’s basically no more than 5.25 minutes of downtime per year!

Releases

  • orchestrator 3.0.3 – auto-provisioning Raft nodes, native Consul support, SQLite or MySQL backed setups, web UI improvements and more. Solid release.
  • MongoDB 3.6 – you can download this soon.
  • MariaDB 10.1.29 – important changes to Mariabackup, InnoDB/XtraDB, and some security fixes
  • Apache Kylin 2.2 – OLAP for Hadoop, originally developed at eBay, has enhanced ACL support amongst other improvements.
  • Cassandra on Azure Cosmos DB

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?

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.

Percona Live Europe Social

Percona Live Europe Social

One for the road…

Percona Live Europe 2017The 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 credit to their stamina – and the fantastic conference agenda – that opening keynotes on both Tuesday and Wednesday were very well attended.

In case you think we might have been prioritizing the Guinness, though, there was the little matter of the lightning talks at the Community Dinner. Seven community-minded generous souls gave up some of their valuable socializing time to share insights into matters open source. Thank you again to Renato Losio of Funambol, Anirban Rahut of Facebook, Federico Razzoli of Catawiki, Dana Van Aken of Carnegie Mellon University, Toshaan Bharvani of VanTosh, Balys Kriksciunas of Hostinger International and Vishal Loel of Lazada.

More about the lightning talks can be seen on the Percona Live Europe website.

Many of the conference treats – coffee, cakes, community dinner – are sponsored and thanks are due once more to our sponsors who helped make Percona Live Europe the worthwhile, enjoyable event that it was.

And so Percona Live Europe drew to a close. Delegates from 43 countries headed home armed with new knowledge, new ideas and new friends. I’ve put together to give a taste of the Percona Live social meetups in this video. Tempted to join us in 2018?

Sláinte!
