This Week in Data with Colin Charles #54: Percona Server for MySQL is Alpha

Join Percona Chief Evangelist Colin Charles as he covers happenings, gives pointers and provides musings on the open source database community.

I consider this to be the biggest news for the week: Alpha Build of Percona Server for MySQL 8.0. Experiment with it in a Docker container. It is missing column compression with dictionary support, native partitioning for TokuDB and MyRocks (excited to see that this is coming!), and encryption key rotation and scrubbing. All in, this should be a fun release to try, test, and also to file bugs for!

Database paradigms are changing, and it is interesting to see Cloudflare introducing Workers KV a key-value store, that is eventually consistent and highly distributed (at their global …

This Week in Data with Colin Charles 53: It’s MariaDB Week PLUS Percona Live Europe Update

Join Percona Chief Evangelist Colin Charles as he covers happenings, gives pointers and provides musings on the open source database community.

This week is clearly what I’d call a “MariaDB week” — plenty of announcements coming from MariaDB Corporation and MariaDB Foundation.

It started with Alibaba Cloud and MariaDB Announce the Launch of ApsaraDB RDS for MariaDB TX, which makes Alibaba Cloud the first public cloud to offer the enterprise offering of MariaDB, MariaDB TX 3.0. It is not available yet as of this announcement for rolling out from the interface, but I expect it will be soon. Exciting, as you can already get MariaDB Server on …

Using ProxySQL to connect to IPv6-only databases over IPv4

It’s 2018. Maybe now is the time to start migrating your network to IPv6, and your database infrastructure is a great place to start. Unfortunately, many legacy applications don’t offer the option to connect to MySQL directly over IPv6 (sometimes even if passing a hostname). We can work around this by using ProxySQL’s IPv6 support which was added in version 1.3. This will allow us to proxy incoming IPv4 connections to IPv6-only database servers.

Note that by default ProxySQL only listens on IPv4. We don’t recommended changing that until this bug is resolved. The bug causes ProxySQL to segfault frequently if listening on IPv6.

In this example I’ll use centos7-pxc57-1 as my database server. It’s running …
