Fun with Bugs #55 - On Some Public Bugs Fixed in MySQL 8.0.2

I do not care much about MySQL 8.0.x at the moment, as it's far from being GA and is work in progress. It is not yet used by customers whom I have to support. But I know about many interesting changes and improvements there that, eventually, are going to influence all main forks and kinds of MySQL. So, it would not be wise to ignore MySQL 8.0.c entirely even for me.

For this post I decided to briefly check what community reported bugs were fixed in the recent release, 8.0.2, based on release notes. For me it's a measure of community interest in MySQL 8.0.x and Oracle's interest in further working with MySQL Community. I ended up with the following, short enough list of bug fixes in the categories I usually care about (InnoDB, partitioning, replication and optimizer):

  • The very first InnoDB bug mentioned in …

Migrating/importing NDB to Cluster Manager w/ version upgrade.

I’ve had some questions from people using MySQL Cluster GPL and wanting to move to using MySQL Cluster Carrier Grade Edition, i.e., they want to use MySQL Cluster Manager, MCM, to make their lives much easier, in particular, upgrading (as well as config change ease and backup history).

All I want to do here is to share with you my personal experience on migrating what’s considered a ‘wild’ NDB Cluster to a MCM managed cluster. It’s just as simple to follow the manual chapter Importing a Cluster into MySQL Cluster Manager so at least you can see how I did it, and it might help someone.

[ If you’re not migrating but just looking for further information on NDB Cluster, and came across this post, please please PLEASE look at the …

The danger of no Primary Key when replicating in RBR (and a partial protection with MariaDB 10.1)

TL;DR: unless you know what you are doing, you should always have a primary key on your tables when replicating in RBR (and maybe even all the time).

TL;DR2: MariaDB 10.1 has an interesting way to protect against missing a primary key (innodb_force_primary_key) but it could be improved.

A few weeks ago, I was called off hours because replication delay on all the slaves from a replication chain
