Orchestrator at GitHub [58848]
By Shlomi Noach, December 8th, 2016

Shlomi Noach blogs, "GitHub uses MySQL to store its metadata: Issues, Pull Requests, comments, organizations, notifications and so forth. While git repository data does not need MySQL to exist and persist, GitHub's service does. Authentication, API, and the website itself all require the availability of our MySQL fleet.

Our replication topologies span multiple data centers and this poses a challenge not only for availability but also for manageability and operations..."

Business Continuity and MySQL Backups [58640]
By Dimitri Vanoverbeke, December 2nd, 2016

Dimitri blogs, "This blog post discusses the business continuity plan around MySQL backups, and how organizations should think about them.

During the years I've worked in IT, I've learned that backups sometimes are a conceptual subject in organizations. Many companies have them, but don't document the associated business continuation plan for them. I experienced this the hard way many many years ago, somewhere around when MySQL 5.0 was still widely used.

In most organizations, there are a couple of business continuity subjects that should be described internally. For example, what is the recovery time objective and what is the recovery point objective. Let's go a bit deeper into both concepts:..."

Make MySQL 8.0 Better Through Better Benchmarking [58641]
By Peter Zaitsev, December 2nd, 2016

Peter blogs, "This blog post discusses how better MySQL 8.0 benchmarks can improve MySQL in general.

Like many in MySQL community, I'm very excited about what MySQL 8.0 offers. There are a lot of great features and architecture improvements. Also like many in the MySQL community, I would like to see MySQL 8.0 perform better. Better performance is what we always want (and expect) from new database software releases.

Rarely do performance improvements happen by accident - they require running benchmarks, finding bottlenecks and eliminating them. This is the area where I think things could use improvement..."

MySQL multi-instance Group Replication on systemd [58448]
Select All From MySQL, November 25th, 2016

Andrew Grimo writes, "In this blog post, I'd like to take a look at a few different things such as MySQL Group Replication, multi-instance MySQL setups on systemd and shell scripting the whole mess to make it easy to build, and easy to rebuild. To be honest, it took a little help from Shinguz's blog to get the systemd setup going. Now that I get it, its really simple and way better than mysqld_multi. Another reference for systemd integration from the mysqlserverteam can be found here..."

By Matt K., November 17th, 2016

Matt writes, "For the past few months we've been spreading the word about our shiny new Data Pipeline: a Python-based tool that streams and transforms real-time data to services that need it. We wrote a series of blog posts covering how we replicate messages from our MySQL tables, how we track schemas and compute schema migrations, and finally how we connect our data to different types of data targets like Redshift and Salesforce..."
