Writing MySQL Proxy in GO for self-learning: Part 2 — decoding handshake packet

After we built a generic TCP proxy, we can continue with our journey. Today’s goal will be to understand the MySQL Protocol, receive, decode, encode and send to the client the first packet sent by the MySQL Server.

MySQL connections threads

Each client connection to MySQL Server handled by a thread. MySQL is portable, so the underhood threads implementation is system dependent (Windows, macOS, and Linux have their own threads implementation).

What important to us, it’s to understand that a single client connection …

Writing MySQL Proxy in GO for self-learning: Part 1 — TCP Proxy

Weekend. Quarantine. If you bored like me, and want to learn something new, you can join my journey of writing yet another MySQL Proxy Server.

In the past, I had a crazy idea of writing MySQL Proxy Server. The first reason was to understand the MySQL Communication Protocol to let me write more efficient programs. The second one was to learn more about low-level network programming concepts in general. Finally, I have time at least to start… and you can join me!

The real usage of MySQL Proxy can vary:

• Testing and benchmarking of the infrastructure
• Testing your applications for dealing with MySQL network failures and delays
• Wrap the MySQL usage with own business layer
• Load balancing
• Multiplexing

There are many users of MySQL in Cloud environment regions. It’s ideal that those MySQL instances are implemented with only private-ips in the respective Subnet. No public-ips. For that matter, all cloud infrastructure resources are ideally placed behind networks that provision only private-ips.  This limits any front-end attack surface for an application stack.  Certainly the up coming MySQL… Read More »

Many things in the MySQL 8.0 Series has evolved. I’ve discussed many of those things in prior blogs such as items like the MySQL-Router w/InnoDB Cluster, plus a Series on Enterprise Backup with InnoDB Cluster Backup & Restore Use Cases. But now its time to update everyone on the evolution of the Yum Repo packaging in MySQL 8.0.18!… Read More »

At MariaDB Foundation, we are proud of MariaDB Server getting plenty of contributions. But we don’t want to get cocky, so here is an update about where we stand, and what we want to make happen. First, we have shown our contribution pride in several places. On 15 February 2019, I tweeted On code contributions, […]

MariaDB Server 10.4 came with a whole lot of Security related changes. Some of them are merely optimizations (like MDEV-15649), some improve existing features to be more robust (MDEV-15473, MDEV-7598) or convenient (MDEV-12835, MDEV-16266). Some are MySQL compatibility features, requested by our users (MDEV-7597, MDEV-13095). But the first thing any MariaDB Server user, whether an […]

The website or mobile app is the storefront for participating in the modern digital era. It’s your portal for inviting users to come and survey your products and services. Much attention focuses on front-end development; this is where the HMTL5, CSS, and JavaScript are coded to develop the landing page that everyone sees when they visit your site.

But the real magic happens on the backend. This is the ecosystem that really powers your website. One writer has articulated this point very nicely as follows:

The technology and programming that “power” a site—what your end user doesn’t see but what makes the site run—is called the back end. Consisting of the server, the database, and the server-side applications, it’s the behind-the-scenes functionality—the brain of a site. …

One of the goals of the MariaDB Foundation is to help new contributors understand the source code and to lower the barrier for new participants. One way to measure this is to look at the number of pull requests received and accepted, as these mostly reflect community contributions. The figures below are for the main […]
