This Week in Data with Colin Charles 29: Percona Live Full Schedule, MariaDB Events, and a Matter of CompatibilityColin Charles
Join Percona Chief Evangelist Colin Charles as he covers happenings, gives pointers and provides musings on the open source database community.
I think the biggest news from Percona-land is that besides the tutorial grid, the schedule for day 1 and day 2 are live! Also notice the many “sub-themes”: a 101 track, using MySQL, MongoDB, cloud, MySQL database software, PostgreSQL, containers & automation, monitoring & ops, and misc. database stuff. Learn from 107 different experts (this number is likely to increase). So register now.
This coming week, Peter Zaitsev, Tom Basil, and I will be in New York. Some of us will be at the MariaDB 2018 Developers Unconference, and all of us will be attending M|18. We have a schedule for the Developers Unconference, and I hope you find time on Sunday to join us as I present MySQL features missing in MariaDB between 12:15-13:00. Being an unconference, it shouldn’t just be a presentation, but also active discussion. I recall during the FOSDEM MySQL DevRoom, MariaDB Foundation developer Vicentiu Ciorbaru assigned to himself support for the super readonly feature (see tweet).
If you have thoughts of what you like in MySQL but are missing from MariaDB Server, please don’t hesitate to tweet at me @bytebot, or even drop me an email: email@example.com. I will happily change and add to the slides until Sunday morning, Eastern Standard Time.
Why is this important? Quite simply, take a look at Todd Farmer’s blog post: Bitten by MariaDB 10.2 Incompatible Change. Here’s Cloudera Manager failing, on specific minor versions of software since the behavior changed (so this particular issue occurs in 10.2.8+ but not before!). I’d definitely spend some time reading the comments as well as the associated Jira. Maybe with 10.3/10.4, it’s time to stop calling it a “drop-in replacement” (an initial goal when I worked on MariaDB Server), and just call it something else. Maybe something for the new Chief Marketing Officer to think about?
- Percona Server for MySQL 5.7.21-20 – some changes to MyRocks, and in case you missed it, did you know that since the previous release there has been some cool work around data at rest encryption? Encryption for the binary & relay logs, and a Keyring Vault plugin (using HashiCorp’s Vault server).
- MariaDB MaxScale 2.2.2 – automatic failover, manual switchover, and automatic rejoin; plus MaxCtrl for management. Will you try it? Keep in mind the license.
- Sharded replica sets – MySQL and MongoDB – a must read by Mark Callaghan (remember he’s active in both MySQL and MongoDB communities).
- A Word About Amazon EBS Volumes Presented As NVMe Devices On C5/M5 Instance Types.
- Meet dbdeployer: the new sandbox maker – in case you missed Giuseppe Maxia’s talk about shifting his love for Perl to Go, the next generation of the famous MySQL Sandbox tool will be written in Go. This is a great blog post telling you all about dbdeployer and the goal of replacing MySQL Sandbox completely.
- PostgreSQL Maximum Table Size – PostgreSQL is exabyte and yottabyte scale, depending on versions you’re using!
- TOP 10 MySQL 8.0 features for DBAs & OPS – must read as MySQL 8 comes close to being GA.
- One year of MySQL Replication Contributions – it is often touted that MySQL does not accept contributions; this is untrue. Here you have contributions, just replication focused from Facebook, Booking.com, Percona, GMO Media Inc, and Alibaba.
