Join Percona Chief Evangelist Colin Charles as he covers happenings, gives pointers and provides musings on the open source database community.
Much is still being talked about the Meltdown/Spectre CPU security vulnerabilities. There’s an interesting Twitter thread showing performance impact on Kafka brokers. Jaime Crespo also writes about how it affects MariaDB Server 10.1.30 – Finding out the MySQL performance regression due to kernel mitigation for Meltdown CPU vulnerability. It’s worth checking out the thread for PostgreSQL too.
Something else worth thinking about, Stephen O’Grady writes Whither the DBA. What do you think? Don’t forget to look below the fold for Robert Treat’s comment too.
Releases
- MariaDB 10.2 now Supported on Amazon RDS – the latest release with window functions, recursive CTEs, ed25519 authentication and more. Note that InnoDB is the default InnoDB, not Percona XtraDB now. Take note of what parameters are supported
- Percona Server for MySQL 5.7.20-19 – this is a big deal as the MyRocks Storage Engine has reached General Availability status.
