This Week in Data: MongoDB Transactions and Spectre/Meltdown Rumble On

Take a look at what's gone on in the world of databases, including looks at MongoDB transactions, the lasting effects of Spectre and Meltdown, and what Amazon is up to.

In case you missed last week’s column, don’t forget to read the fairly lengthy FOSDEM MySQL & Friends DevRoom summary.

From a Percona Live Santa Clara 2018 standpoint, beyond the tutorials getting picked and scheduled, the talks have also been picked and scheduled (so you were very likely getting acceptance emails from the Hubb.me system by Tuesday). The rejections have not gone out yet but will follow soon. I expect the schedule to go live either today (end of week) or early next week. Cheapest tickets end March 4, so don’t wait to register!

Amazon Relational Database Service has had a lot of improvements in 2017, and the excellent summary from Jeff Barr is worth a read: Amazon Relational Database Service – Looking Back at 2017. Plenty of improvements for the MySQL, MariaDB Server, PostgreSQL and Aurora worlds.

Spectre/Meltdown and its impact are still being discovered. You need to read Brendan Gregg’s amazing post: KPTI/KAISER Meltdown Initial Performance Regressions. And if you visit Percona Live, you’ll see an amazing keynote from him too! Are you still using MyISAM? MyISAM and KPTI – Performance Implications From The Meltdown Fix suggests switching to Aria or InnoDB.

Probably the biggest news this week though? Transactions are coming to MongoDB 4.0. From the site, “MongoDB 4.0 will add support for multi-document transactions, making it the only database to combine the speed, flexibility, and power of the document model with ACID guarantees. Through snapshot isolation, transactions will provide a globally consistent view of data, and enforce all-or-nothing execution to maintain data integrity.”. You want to read the blog post, MongoDB Drops ACID (the title works if you’re an English native speaker, but maybe not quite if you aren’t). The summary diagram was a highlight for me because you can see the building blocks, plus future plans for MongoDB 4.2.
