MySQL Support Engineer's Chronicles, Issue #6

Previous post in series was published almost 4 months ago, but I do not plan to end it. So, let me quickly discuss some of problems I worked on or was interested in so far in June, and provide some useful links.

Back on June 2 I had to find out what exact files are created by MariaDB's ColumnStore when I create a table in this storage engine. Actually in recent versions one can check the tables in the INFORMATION_SCHEMA, but if still wonders why are all these directories with numbers in the names (/usr/local/mariadb/columnstore/data1/000.dir/000.dir/011.dir/193.dir/000.dir/FILE000.cdf), please, check also this …

MySQL Encryption at Rest – Part 1 (LUKS)

In this first of a series of blog posts, we’ll look at MySQL encryption at rest.

At Percona, we work with a number of clients that require strong security measures for PCI, HIPAA and PHI compliance, where data managed by MySQL needs to be encrypted “at rest.” As with all things open source, there several options for meeting the MySQL encryption at rest requirement. In this three-part series, we cover several popular options of encrypting data and present the various pros and cons to each solution. You may want to evaluate which parts of these tutorials work best for your situation before using them in production.

Part one of this series is implementing disk-level encryption using crypt+LUKS.

In MySQL 5.7, InnoDB has built-in encryption features. This solution has some cons, …

Speaking in May 2017

It was a big April if you’re in the MySQL ecosystem, so am looking forward to other events that have different focus and a different base, so to speak. See you at:

  • rootconf – May 11-12 2017 – Bangalore, India. My first Rootconf was last year, and it was a great event; I look forward to going there again this year, to talk about capacity planning for your databases. If you register with this link you get a 10% discount.
  • Open Source Data Center Conference – May 16-18 2017 – Berlin, Germany. I’ve enjoyed my trips to OSDC in the last few years, and they’re on their last tickets now …

Fun with Bugs #52 - On Some Bugs Fixed in MySQL 5.7.18

I had not reviewed MySQL 5.7 release notes for quite a some time in this series. Last time I checked it was MySQL 5.7.15. So, as soon as I noted new release, 5.7.18, I decided to check the release notes for any interesting fixed bug (reported by Community users in public) in the areas I am interested in: InnoDB, replication, optimizer and few others.

Note that recently most of the bugs fixed are internal only, found by Oracle engineers that never cared (or are not allowed, who knows) to report them in public, so this blog post is not even remotely a full review of what's fixed in MySQL 5.7.18 and is not a replacement for reading the detailed …

Accessing Oracle tables via MariaDB CONNECT engine and ODBC

In my previous working environment it was typical to consider MariaDB Server as just a set of "random" storage engines mixed together, sometimes for unclear reasons and with questionable extra value. But even at that times I was already impressed by some features of one of the engines supported only by MariaDB, CONNECT. PIVOT table type specifically was of interest in a couple of customer cases I had to work on, but I quickly found out that the engine does not work with Oracle's MySQL or Percona Server, and thus had to forget about it for some time.

Recently while working in MariaDB I've got several more chances to deal with some new CONNECT use cases (and some related problems, that ended up mostly minor or caused by ignorance). This engine …

Speaking in April 2017

Its been a while since I’ve blogged (will have to catch up soon), but here’s a few appearances:

  • How we use MySQL today – April 10 2017 – New York MySQL meetup. I am almost certain this will be very interesting with the diversity of speakers and topics.
  • Percona Live 2017 – April 24-27 2017 – Santa Clara, California. This is going to be huge, as its expanded beyond just MySQL to include MongoDB, PostgreSQL, and other open source databases. Might even be the conference with the largest time series track out there. Use code COLIN30 for the best discount at registration.

I will also be in attendance at the …

MySQL Support Engineer's Chronicles, Issue #5

A lot of time passed since my previous post in this series. I was busy with work, participating in FOSDEM, blogging about profilers and sharing various lists of MySQL bugs. But I do not plan to stop writing about my usual weeks of doing support engineer's job. So, time for the next post in this series, based on my random notes taken during the week here and there.

This week started for me with checking recent MySQL bug reports (actually I do it every day). …
