Join Percona Chief Evangelist Colin Charles as he covers happenings, gives pointers and provides musings on the open source database community.
Much of last week, there was a lot of talk around this article: New research shows 75% of ‘open’ Redis servers infected. It turns out, it helps that one should always read beyond the headlines because they tend to be more sensationalist than you would expect. From the author of Redis, I highly recommend reading Clarifications on the Incapsula Redis security report, because it turns out that in this case, it is beyond the headline. The content is also suspect. Antirez had to write this to help the press (we totally need to help keep reportage accurate).
Not to depart from the Redis world just yet, but Antirez also had some collaboration with the Apple Information Security Team with regards to the Redis Lua subsystem. The details are pretty interesting as documented in Redis Lua scripting: several security vulnerabilities fixed because you’ll note that the Alibaba team also found some other issues. Antirez also ensured that the Redis cloud providers (notably: Redis Labs, Amazon, Alibaba, Microsoft, Google, Heroku, Open Redis and Redis Green) got notified first (and in the comments, compose.io was missing, but now added to the list). I do not know if Linux distributions were also informed, but they will probably be rolling out updates soon.
In the “be careful where you get your software” department: some criminals have figured out they could host some crypto-currency mining software that you would get pre-installed if you used their Docker containers. They’ve apparently made over $90,000. It is good to note that the Backdoored images downloaded 5 million times finally removed from Docker Hub. This, however, was up on the Docker Hub for ten months and they managed to get over 5 million downloads across 17 images. Know what images you are pulling. Maybe this is again more reason for software providers to run their own registries?
James Turnbull is out with a new book: Monitoring with Prometheus. It just got released, I’ve grabbed it, but a review will come shortly. He’s managed all this while pulling off what seems to be yet another great O’Reilly Velocity San Jose Conference.
Releases
A quiet week on this front.
Link List
- INPLACE upgrade from MySQL 5.7 to MySQL 8.0
- PostgreSQL relevant: What’s is the difference between streaming replication vs hot standby vs warm standby ?
- A new paper on Amazon Aurora is out: Amazon Aurora: On Avoiding Distributed Consensus for I/Os, Commits, and Membership Changes. It was presented at SIGMOD 2018, and an abstract: “One of the more novel differences between Aurora and other relational databases is how it pushes redo processing to a multi-tenant scale-out storage service, purpose-built for Aurora. Doing so reduces networking traffic, avoids checkpoints and crash recovery, enables failovers to replicas without loss of data, and enables fault-tolerant storage that heals without database involvement. Traditional implementations that leverage distributed storage would use distributed consensus algorithms for commits, reads, replication, and membership changes and amplify cost of underlying storage.” Aurora, as you know, avoids distributed consensus under most circumstances. Short 8-page read.
- Dormando is blogging again, and this was of particular interest — Caching beyond RAM: the case for NVMe. This is done in the context of memcached, which I am certain many use.
- It is particularly heartening to note that not only does MongoDB use Linkbench for some of their performance testing, they’re also contributing to making it better via a pull request.
Industry Updates
Trying something new here… To cover fundraising, and people on the move in the database industry.
- Kenny Gorman — who has been on the program committee for several Percona Live conferences, and spoken at the event multiple times before — is the founder and CEO of Eventador, a stream-processing as a service company built on Apache Kafka and Apache Flink, has just raised $3.8 million in funding to fuel their growth. They are also naturally spending this on hiring. The full press release.
- Jimmy Guerrero (formerly of MySQL and InfluxDB) is now VP Marketing & Community at YugaByte DB. YugaByte was covered in column 13 as having raised $8 million in November 2017.
