This Week in Data with Colin Charles 31: Meltdown/Spectre Performance Regressions and Percona Live 2018Colin Charles
Join Percona Chief Evangelist Colin Charles as he covers happenings, gives pointers and provides musings on the open source database community.
Have you been following the Meltdown/Spectre performance regressions? Some of the best blog posts have been coming from Brendan Gregg, who’s keynoting at Percona Live this year. We’ve also got Scott Simpson from Upwork giving a keynote about how and why they use MongoDB. This is in addition to all the other fun talks we have, so please register now. Don’t forget to also book your hotel room!
Even though the Percona Live conference now covers much more than just MySQL, it’s worth noting that the MySQL Community Awards 2018: Call for Nominations! is happening now. You have until Friday, March 15, 2018, to make a nomination. Winners get into the Hall of Fame. Yes, I am also on the committee to make selections.
Another highlight: Open-sourcing a 10x reduction in Apache Cassandra tail latency by Dikang Gu of Instagram (Facebook). This is again thanks to RocksDB. Check out Rocksandra, and don’t forget to register for Percona Live to see the talk: Cassandra on RocksDB.
This week, I spent some time at Percona Headquarters in Raleigh, North Carolina. The building from the outside is pictured well in Google Maps. I thought it might be fun to show you a few photos (the office is huge with quite a handful working there despite the fact that Percona is largely remote).
- Percona XtraDB Cluster 5.7.21-29.26
- Percona Monitoring and Management 1.8.1 – improvements for ProxySQL, and improvements for Amazon RDS.
- Percona Server for MongoDB 3.4.13-2.11 – MongoRocks fixes.
- MySQL 8.0.5 community edition preview for Oracle Linux 7 for ARM64 (preview) – we don’t have 8.0.5 yet as of this writing (8.0.4rc is the most current), but glancing at the documentation, there are also some unused version numbers.
- Amazon Aurora with MySQL Compatibility is Available in the Asia Pacific (Singapore) Region – they only announced the 3rd AZ in mid-January, and now you have Aurora MySQL in Singapore too!
- MySQL security for real users – a great read from Giuseppe Maxia, also the bit about the disconnect between developers and the user community
- TPCC-Like Workload for Sysbench 1.0 – Nice to be able to have a TPC-C like workload in sysbench.
- Migrating MySQL Users to Amazon RDS
- HTTP Analytics for 6M requests per second using ClickHouse
- The Postgres 10 feature you didn’t know about: CREATE STATISTICS
- GitHub’s Sam Kotler writes an excellent incident report: February 28th DDoS Incident Report. I hope you’ve also read Cloudflare’s Memcrashed – Major amplification attacks from UDP port 11211 note (this is why last week I wrote about the new release of memcached).
