MySQL Contributions status

This post is an update to the status of various MySQL bugs (some with patches) that I’ve filed over the past couple of years (or that people around me have). I’m not looking at POWER specific ones, as there are these too, but each of these bugs here deal with general correctness of the code base.

Firstly, let’s look at some points I’ve raised:

  • Incorrect locking for global_query_id (bug #72544)
    Raised on May 5th, 2014 on the internals list. As of today, no action (apart from Dimitri verifying the bug back in May 2014). There continues to be locking that perhaps only works by accident around query IDs.Soon, this bug will be two years old.
  • Endian code based on CPU type rather than endian define (bug …

MySQL Support People - Percona Support

I planned to continue this series of posts with the one about MySQL Support engineers who joined us in Oracle while I was working there, but based on recent events in my life I'd prefer to postpone it and move directly to the team I worked for during last 3+ years, Percona Support Team.

Disclamer: In the list below I still try to pay attention to public contribution by each of engineers mentioned to MySQL Community, mostly in a form of bug reports. This is not the only way they contributed, but I have to stick to this format in current series of posts. I also base my comments mostly on my memory and quick search of public sources of information, so I may be mistaking about the roles, time periods and other details. Please, inform me if you think there is something to fix.

So, here is the list of my former colleagues who formed the best MySQL Support team in the industry in 2013-2015 while working with me in …
