Fun with Bugs #42 - Bugs Fixed in MySQL 5.7.12
+0 Vote Up -0Vote Down

MySQL 5.7.12 was released more than 2 weeks ago. New features introduced there in a form of "rapid plugins" are widely discussed, but I am more interested in bugs reported by MySQL Community users that are fixed there. Unfortunately I do not see MySQL Community Release Notes by Morgan (like this) for quite a some time, so I have to continue describing key bug fixes and name people who reported and verified bugs in my "Fun with Bugs" series.

MariaDB MaxScale is mentioned in many blog posts recently. It's Application of the Year 2016 after all! I'd like to test it, follow posts like this etc, all that on my favorite and readily available testing platforms that are now Ubuntu of all kinds and, surely, Fedora 23 (on my wife's workstation, the most powerful hardware at hand).

Being Naive About Folder Paths
+0 Vote Up -0Vote Down

Recently I worked on a feature that involved displaying a list of Folders using an auto-complete field. A simple enough task, but one that had a bit of complexity behind it. For starters, each organization in our system has their own "folder hierarchy", or a tree structure of folders, that could be one to many layers deep. The second thing being that the UI we wanted -- auto-complete -- meant that we would need to "search" through the folders to find a match (based on the user's input) as well as display the path information (where the folder lives) so that the user can differentiate folders if they happen to have the same or similar name. Since it was …

Why is ColumnStore important?

Fri, 2016-04-29 08:22nishantvyas

Relational databases store data in rows because a typical SQL query looks for multiple fields within a record. For example, if you ask for name, zip code and email address of all your customers in New York, the result is presented in rows, with each row containing several fields from a single record. Row structures are also well optimized to handle a lot of inserts and updates.

But analytic queries are better handled with a column structure because they are more likely to go deep on a column of data, most queries relate only to a tiny subset of all the available columns and they’re also mostly read-only. For example, …

“Toy” database on mainframes
+0 Vote Up -0Vote Down

While much less common than 10 or 15 (err… even 20) years ago, you still sometimes hear MySQL being called a “toy” database. The good news is, when somebody says that, they’re admitting ignorance and you can help educate them!

Recently, a fellow IBMer submitted a pull request (and bug) to start having MySQL support on Z Series (s390x).

Generally speaking, when there’s effort being spent on getting something to run on Z, it is in no way considered a toy by those who’ll end up using it.

Writing SQL that works on PostgreSQL, MySQL and SQLite

I am one of those crazy people who attempts to write SQL that works on SQlite, MySQL and PostgreSQL. First I should explain why:

This is all for my project sabre/dav. sabre/dav is a server for CalDAV, CardDAV and WebDAV. One of the big design goals is that it this project has to be a library first, and should be easily integratable into existing applications.

To do this effectively, it’s important that …
