TokuDB Hotbackup and Replication

TokuDB Hotbackup is a solution that allows you to do backups on the fly. It works as a library that intercepts certain system calls that duplicate data written to already copied parts of files, so that at the end of the backup process the copied files contain the same content as the original files. There are several blog posts describing how TokuDB Hot Backup works in details:

Binlog expiry now in seconds (MySQL 8.0)

In this blog we are going to view about a  new feature in latest release MySQL 8.0.1 for MySQL Replication . It is binlog_expire_logs_seconds.

Previously we can set the expire logs for binlogs in number of days. By using the new feature (binlog_expire_logs_seconds) we can see set the expire time into number of seconds.

The both expire_logs_days and binlog_expire_logs_seconds works when the binlog rotate happens in the server.

The ultimate usage of this feature will be used to set expire periods smaller than a day by providing another extra variable.

The new variable binlog_expire_logs_seconds, can be used in those cases where the expire period is not an integral …

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 …

"MySQL High Availability tools" followup, the missing piece: orchestrator

I read with interest MySQL High Availability tools - Comparing MHA, MRM and ClusterControl by SeveralNines. I thought there was a missing piece in the comparison: orchestrator, and that as result the comparion was missing scope and context.

I'd like to add my thoughts on topics addressed in the post. I'm by no means an expert on MHA, MRM or ClusterControl, and will mostly focus on how orchestrator tackles high availability issues raised in the post.

What this is

This is to add insights on the complexity of failovers. Over the duration of three years, I always think I've seen it all, and then get hit by yet a new crazy scenario. Doing the right thing automatically is difficult.

In this post, I'm …

Fun with Bugs #50 - On Bugs Tagged as "missing manual"

Back in January 2014, some time after many nice people kindly asked me to shut up stop writing about MySQL bugs on Facebook several times per day, I decided to start reading the fine MySQL Manual more carefully than before and report not only typos there, but also any topic or detail not properly explained. Usually these reports, tagged as "missing manual", were the result of careful study of the documentation based on real user question or customer issue. So, most of these reports came from real life, and missing information badly affected poor MySQL users.

Today, for this issue #50 in my series of posts about MySQL bugs, I decided to list and …
