Downsizing to SSDs
+1 Vote Up -0Vote Down

System management can be a big deal. At Etsy, we DBAs have been feeling the pain of getting spread too thin. You get a nice glibc vulnerability and have to patch and reboot hundreds of servers. There goes your plans for the week.

We decided last year to embark on a 2016 mission to get better performance, easier management and reduced power utilization through a farm reduction in server count for our user generated, sharded data.

Scoping the Problems

Taking on a massive project to replace your entire fleet of hardware is not an easy sell, especially when on the surface it seems like everything is fine. As DBAs, we experienced …

Source of Truth or Source of Madness?
+0 Vote Up -0Vote Down

This year at Etsy, we spun up a “Database Working Group” that talks about all things data. It’s made up of members from many teams: DBA, core development, development tools and data engineering (Hadoop/Vertica). At our last two meetings, we started talking about how many “sources of information” we have in our environment. I hesitate to call them “sources of truth” because in many cases, we just report information to them, not action data based on them. We spent a session whiteboarding all of of these sources and drawing the relationships between …

MySQL 5.7 multi-source replication – automatically combining data from multiple databases into one
+1 Vote Up -0Vote Down

MySQL’s multi-source replication allows you to replicate data from multiple databases into one database in parallel (at the same time). This post will explain and show you how to set up multi-source replication. (WARNING: This is a very long and detailed post. You might want to grab a sandwich and a drink.)

In most replication environments, you have one master database and one or more slave databases. This topology is used for high-availability scenarios, where the reads and …

Use MySQL to store data from Amazon’s API via Perl scripts
+1 Vote Up -0Vote Down

I really like Amazon.com and I have been a Prime member for several years. Along with millions of different items for sale, Amazon has an affiliate program, where you can earn money advertising products on your web site. When a visitor to your site clicks on a link and orders a product from Amazon, you earn a small commission on the total sale. As an affiliate, you have access to Amazon’s Product Advertising API for obtaining product information. But, you can use this information for many other purposes.

Motivation to Migrate RDBMS
+1 Vote Up -0Vote Down

http://www.itnews.com/article/3004953/use-oracles-database-watch-out-for-this-dec-1-deadline.html

Companies that use a standard edition of Oracle’s database software should be aware that a rapidly approaching deadline could mean increased licensing costs.

Speaking from experience (at both MySQL AB and Open Query), typically, licensing/pricing changes such as these act as a motivator for migrations.

Migrations are a nuisance (doesn’t matter from/to what platform) and are best avoided as they’re intrinsically …

Add RSS feeds to your Twitter stream using MySQL and Perl
+0 Vote Up -0Vote Down

Adding good content to Twitter can be a pain. I can’t do it during working hours, and I don’t have much time at night. But, the more content you have, the more followers you can gain, and the more your original tweets can be seen (hopefully). I have written several posts about using the latest Perl-Twitter API – Net::Twitter::Lite::WithAPIv1_1, so you might want to check these out as well.

Use MySQL and Perl to automatically find, follow and …
