Tab housekeeping but I also realise that people seem to have missed announcements, developments, etc. that have happened in the last couple of months (and boy have they been exciting). I think we definitely need something like the now-defunct MySQL Newsletter (and no, DB Weekly or NoSQL Weekly just don’t seem to cut it for me!).
During @scale (August 31), Yoshinori Matsunobu mentioned that MyRocks has been deployed in one region for 5% of its production workload at Facebook.
By October 4 at the Percona Live Amsterdam 2016 event, Percona CEO Peter Zaitsev said that MyRocks is coming to Percona Server (blog). On October 6, it was also announced that MyRocks is coming to MariaDB Server 10.2 (note I created MDEV-9658 back in February 2016, and that’s a great place to follow Sergei Petrunia’s progress!).
Rick Pizzi talks about MyRocks: migrating a large MySQL dataset from InnoDB to RocksDB to reduce footprint. His blog also has other thoughts on MyRocks and InnoDB.
Of course, checkout the new site for all things MyRocks! It has a getting started guide amongst other things.
Proxies: MariaDB MaxScale, ProxySQL
With MariaDB MaxScale 2.0 being relicensed under the Business Source License (from GPLv2), almost immediately there was a GPLScale fork; however I think the more interesting/sustainable fork comes in the form of AirBnB MaxScale (GPLv2 licensed). You can read more about it at their introductory post, Unlocking Horizontal Scalability in Our Web Serving Tier.
ProxySQL has a new webpage, a pretty active mailing list, and its the GPLv2 solution by DBAs for DBAs.
Vitess 2.0 has been out for a bit, and a good guide is the talk at Percona Live Amsterdam 2016, Launching Vitess: How to run YouTube’s MySQL sharding engine. It is still insanely easy to get going (if you have a credit card), at their vitess.io site.
