Splice Machine open-sources its “dual engine” RDBMS (splicemachine.com)

Doesn't look open source to me yet. The only things I can find are this announcement and a Surveymonkey page where would-be contributors can indicate what they think they could contribute to the project. I couldn't find any licensing information.

The URL also mentions "announces move to open source offers early access to developers".

From what I can read, this could mean a not too well executed 'real open source' release, a "let's try and find free developers by letting them work with the source, but not deploy it commercially", or anything in-between.



Please expect it this summer, I will post here once we announce its availability.


Splice Machine will be available on github this summer. We initially wanted mentors and contributors to help us prepare for open source. If you are interested, ping us and we will get you access to source code.


It sounds like Apache 2.0 from talking to them at spark summit.


That is correct, it will be Apache 2.0


Has anyone used this successfully who would like to comment on it?

We ran a brief test about a year ago and found performance was not acceptable given the amount of hardware dedicated to the test cluster, which they set up for us to their specifications in their hosting facility after multiple in-house attempts were disqualified post-completion (...a frustrating waste of time) by their SE. I'm not sure how fair we were with the workload we designed for the test; Our management seemed to think this was going to be "Easy Scale Out Big Data MSSQL!" but I came away thinking this was not a product you could just port an existing application to and be done with.


I am sorry to hear that. We spent a lot of time trying to get SQL compliance nailed (Triggers, constraints, etc.). Our 2.0 product with Spark for our analytical workloads has helped our performance and resource isolation significantly.

I hope once we open source you might try it again.


Sounds interesting, do they have any spatial (PostGIS like) capabilities? I couldn't find anything, but curious if its something they are going to have.


No spatial yet. We use Spark for our analytical engine so it would not be a stretch to implement...
