When troubleshooting a MySQL crash, having only the error log is rarely enough to pinpoint the exact root cause. To truly understand what happened, we need to go deeper—into the memory state of the process at the moment it crashed. That’s where GDB, the GNU Debugger, comes in. GDB lets us inspect a core dump […]

We all know MySQL InnoDB ClusterSet, a solution that links multiple InnoDB Clusters and Read Replicas asynchronously to easily generate complex MySQL architectures and manage them without burdensome commands. All this thanks to the MySQL Shell’s AdminAPI. This is an example of MySQL InnoDB ClusterSet using two data centers: Let’s explore how we can automate […]

In my previous blog post, Understanding trx-consistency-only on MyDumper Before Removal, I talked about --trx-consistency-only removal, in which I explained that it acts like a shortcut, reducing the amount of time we have to block the write traffic to the database by skipping to check if we are going to backup any non-transactional tables. Now, […]

We're now expanding OCI Database Management capabilities with a new set of enhanced monitoring features - designed to reduce operational burden on DBAs and developers, strengthen observability, and support high availability across modern MySQL deployments.

I’ve hacked together a horrible thing in Python, and made it available in mysql-release-notes

on GitHub.

It’s a Python project (done with uv) that downloads all MySQL release notes, dumps them into a release_notes folder, and then parses them, pushing everything into a database.

It uses SQLAlchemy and mysqlclient to connect to the database.

It generates a schema (not preserving any data), and fills it with all the release notes we have.

The schema is a simple star.

For each release, we have many issues, and for each issue we store a number of properties. Properties aren’t stored as plain text — they’re encoded, and we only keep the property ID.

Sample queries like

select t.contributor,
       min(r.release_date), min(r.version),
       max(r.release_date), max(r.version), …
