Our Top10 Open Source Time Series databases blog has been very popular, with over 10,000 views and growing. It sat on the front page of Reddit /r/programming for a day or two and we got a bunch of traffic from HackerNews and DBWeekly. The raw data in the spreadsheet that accompanies the blog has been constantly updated ever since by a team of volunteers which now includes some of the database authors.
Today is the culmination of over a years worth of hard work (and significantly more than that for its creator Heinz). We're releasing DalmatinerDB v0.2 which is a free, highly scalable time series database built on top of Riak Core that features an expressive data model and query language.
Databases are a crazy topic and it seems everyone has an opinion. The trouble is that opinions are like belly buttons: just because everyone has one it doesn’t mean they are useful for anything.
With that in mind, I decided to pen a magnum opus of my own opinions. Something I can point people to next time someone asks 'have you tried X'?
Disclaimer: Outlyer helps build DalmatinerDB, so there is a massive conflict of interest.

We've started to use a new time-series database called Dalmatiner DB which relies on the filesystem for features like compression and consistency checking. Initially this database was written for SmartOS which has native ZFS support but given the maturity of ZFS on Linux we thought we'd run our setup on Linux.
