Percona Live Europe 2017 Dublin

We’ve spent a lot of time in the last few months organizing Percona Live Europe Dublin. I want to thank all the speakers, sponsors and attendees for helping us to pull off yet another great event. While we’ll provide some perspectives, thoughts and feedback soon, all the early mornings, jam-packed meetings and the 4 am bedtimes means I’ll probably talk about this event in my next column!

In the meantime, save the date for Percona Live Santa Clara, April 23-25 2018. The call for papers will open in October 2017.

Releases

• MariaDB 10.1.27. Percona XtraDB and TokuDB got updated from 5.6.37-82.2. Encryption gets tighter when it comes to temporary tables (fixes MDEV-12634).
• MySQL 8.0 is now a Release Candidate. You’ll want to read the highlights. As well as changes in replication.
• Percona XtraDB Cluster 5.7.19-29.22. New instrumentation to get a unified view of the cluster, new Percona XtraBackup support for encrypting data and backup threads.

Link List

• Why SQL is beating NoSQL, and what this means for the future of data – was SQL really being left for dead? It doesn’t feel like that to me, but this is an interesting read from our friends at TimeScale.
• It’s become unfashionable to talk about MariaDB MaxScale after the change to business source licensing, but after all this time (over a year now), there is a “list” of projects that use the BSL, including the ability to backup and restore MariaDB ColumnStore.
• Yahoo! makes Vespa open source. At Yahoo! this is the big data processing and serving engine.
• MySQL 8.0 Will Bring Unicode 9.0, Schema-less JSON, Greater Geospatial Support
• MariaDB ColumnStore engineer, Andrew Hutchings writes about Correcting MariaDB ColumnStore Benchmarks. “The moral of this story is don’t trust other people’s benchmarks.” I would like to see some MariaDB ColumnStore vs. ClickHouse benchmarks!
• Migrating a database from InnoDB to MyRocks – Yoshinori Matsunobu, speaker at Percona Live Europe Dublin (and many other such events) and MyRocks hacker, tells us how they migrated Facebook’s UDB completely last month. The UDB maintains Facebook’s social graph, and they cut their storage usage in half! Also, “Finally, we will work to support MyRocks for the upcoming MySQL 8.0,” is very promising because this shows continued investment in MyRocks and MySQL by Facebook.
