Re: [Neo4j] Neo4j Licensing

Hello

If you use HA then your code also needs to be open source


Well, more than open source, your code has to be GPL-compatible

Hello Manav, 
 
I am not a lawyer, so what follows here is an opinion. 
 
gt; My question is pretty simple. I am creating a website which uses neo4j 
gt; as its database. Now if I want high availability and monitoring for my db 
, 
gt; do I need commercial license ? or Agpl3 will be fine with my use case. 
 
If you use HA then your code also needs to be open source. That's one of the 
conditions of the AGPL. It prevents people from deriving value from using open 
source software without giving back. 
 
If you open source your stack in accordance with AGPLv3 then you can use HA 
without paying. If you cannot open source your stack then you need to obtain 
Neo4j under a different license. Neo Technology will be happy to provide a 
paid-for commercial license. 
 
gt; If I need commercial license then I will not be able to use it because of 
gt; lack of budget! Can I create a reliable website using only community 
edition 
gt; of Neo4j? 
 
That depends on your situation. If you can tolerate downtime in your app, then 
you might not need HA. If you don't need read scale then you might not need HA. 
If you want to write a lot of crazy plumbing yourself you might not need HA. 
You are best placed to make those design calls since you know the design of 
your system. 
 
Remember that although Neo4j is fanatically open source (you can read the code 
of what you're using), not all of Neo4j is always free - if you're using Neo4j 
in a closed-source commercial environment, then you should obtain a commercial 
license otherwise you may even fall foul of the AGPL.

Hey Graphistas, 
 
there is a new article on NOSQL databases on InfoWorld. The part for Neo4j is 
badly researched. If anyone of you thinks he could add some useful information 
for the reader, please do so in the commenting section. 
 
Thanks so much
