This Week in Data with Colin Charles 40: a Peak at Blockchain, Lots of MariaDB N...

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

Shortly after thelast dispatch, I jetted off for a spot of vacation (which really meant I was checking out the hype behind Blockchain with a database developer lens at the Blockchain Week NYC ), and then some customer visits in Seoul, which explains the short hiatus. Here’s to making this more regular as the summer approaches.

I am about to embark on a fairly long trip, covering a few upcoming appearances: Lisbon for the Percona Engineering meeting, SouthEastLinuxFest in Charlotte, the Open Source Data Centre Conference in Berlin and then the DataOps Barcelona event. I have some discount codes: 50% discount for OSDC with the code OSDC_FOR_FRIENDS, and 50% discount for DataOps Barcelona with the code dataopsbcn50 . Expect this column to reflect my travels over the next few weeks.

There has been a lot of news on the MariaDB front: MariaDB 10.3.7 went stable/GA! You might have noticed more fanfare around the release name MariaDB TX 3.0 , but the reality is you can still get this download from your usual MariaDB Foundation site. It is worth noting that the MariaDB Foundation 2017 financials have also been released. Some may have noticed a couple months back there was a press release titled  Report “State of the Open-Source DBMS Market, 2018” by Gartner Includes Pricing Comparison With MariaDB. This led to a Gartner report on the State of the Open-Source DBMS Market, 2018 ; although the report has since been pulled. Hopefully we see it surface again.

In the meantime, please do try out MariaDB 10.3.7 and it would be great to hear feedback. I also have an upcoming Percona webinar on MariaDB Server 10.3 on June 26 2018 — when the sign up link appears, I will be sure to include it here.

Well written, and something worth discussing: Should Red Hat Buy or Build a Database? . The Twitter discussion is also worth looking at.

Releases

• Google Cloud Platform and Confluent partner to deliver a managed Apache Kafka service
• PostgreSQL 11 Beta 1
• Percona Server for MySQL 5.7.22-22 – encryption for temporary files, but I think an important bug fix is around SHOW GLOBAL STATUS and data drift (affects monitoring systems) – an  upstream bug , with code contributed upstream too (just how open source should work!).
• ProxySQL 1.4.9
• Percona Server for MySQL 5.6.40-84.0 – a good release for TokuDB users
• MariaDB 10.2.15
• MongoDB 4.0 Release Candidate 0 – this is big, with multi-document ACID transactions. I’ve signed up for M040: New Features and Tools in MongoDB 4.0 at MongoDB University.

Link List

• Thanos which is Prometheus at scale.
• PostgreSQL 11 Partitioning Improvements
• Fun with SQL: Recursive CTEs in Postgres – these should be repeatable in MySQL 8 / MariaDB Server 10.3
• Production Readiness Checklist – are you ready to go into production on AWS? Useful, if you like checklists (I do), and want to focus on your deployment and infrastructure at AWS.
• sled , a new alpha database, using zstd compression, with plans to, “beat LSM trees for reads and traditional B+ trees for writes”.

Upcoming appearances

• SouthEastLinuxFest – Charlotte, NC, USA – June 8-10 2018
• Open Source Data Centre Conference – Berlin, Germany – June 12-13 2018
