I've just started to learn the Neo4j graphs db. I have a question:
What is the difference between neo4j enterprise and neo4j community for windows?
You can find a list of differences on the price comparison overview.
Features the Open Source version lacks are:
High-Performance Cache
Clustering
Online Backup
Advanced Monitoring
The paid licenses also come with a support contract (you can ask for help from people who will not downvote, edit or close your questions).
Neo4j Enterprise just has more 'enterprise features' such as clustering and additional security for example. The comparison link the other poster provided is good to see the differences between enterprise and community server but it does not mention that Neo4j Enterprise is also free under it's open source license! I would just focus on Neo4j server, not the new 'platform' they are now pushing.
If you don't want to play with their Neo4j Desktop under a trial agreement, you can go straight to Neo4j Enterprise server and run it. It starts the same way as the community edition and is open source under the [AGPLv3 license] https://www.gnu.org/licenses/agpl-3.0.en.html.
You can download Neo4j Enterprise versions before 3.3.0 from the neo4j distribution site below. (3.2.8 is the last version that includes the AGPL license on their distribution site.)
http://dist.neo4j.org/neo4j-enterprise-3.2.8-windows.zip
OR
If you want to use the newest free Neo4j Enterprise edition (currently 3.3.1 as of today) then you can download the free open source binaries we package from source for our government clients at https://igovsol.com/downloads.html
Once you download the zip file to the following to get started. (Assuming you have JAVA setup on your windows machine.)
https://neo4j.com/docs/operations-manual/current/installation/windows/
1) Right-click the downloaded file, click Extract All.
Change directory to top-level extracted directory.
2) Run bin\neo4j console
3) Stop the server by typing Ctrl-C in the console.
The enterprise package is 100% free under it's open source AGPL license.
Unzip the package you download and you can verify it by looking at the LICENSE.txt
If you are curious about learning why you can't get the free AGPL binaries after 3.3.0 - checkout a blog post I wrote at https://blog.igovsol.com/2017/11/14/Neo4j-330-is-out-but-where-are-the-open-source-enterprise-binaries.html

My neo4j community database reach near 1TB and I have only 64GB of RAM , can I use fabric to scale the database horizontally and share the load between different servers or fabric is only for enterprise licensed neo4j versions?
From the Getting Started with Neo4j Fabric Blog:
Fabric is an Enterprise Only feature, meaning it is not available for the Neo4j Community Edition.
The licensing FAQ says:
Neo4j Enterprise Edition is also available for free for a number of uses
You could state your use case and ask them for a free Enterprise license maybe.
The community edition doesn't have an option for scaling/sharding.
I would like to use Neo4j to learn how graph databases work and make some experiences with my own datasets. According to that and since Neo4j claims to be open source I've downloaded the Windows Neo4j Desktop version, but every project and database initialized shows the "Enterprise" attribute which means that I just initialized the Enterprise edition.
Any idea how to setup a project and a database based on the community edition?
Solved it. If you dont setup path variables you have enter the bin directory via cmd and type "neo4j.bat install-service" and then neo4j.bat to start the database-server. The officiall installation instructions should have those details.
just open a commandline in the bin folder. There you execute the command "neo4j.bat console" which creates a local server, that you then reach via localhost:7474.
The neo4j Download Center allows you to choose between downloading the Enterprise Edition, the Community Edition, and the Desktop.
I'm trying to make the config flag dbms.read_only=true working with Neo4j community edition (I know there are user roles in the enterprise, but I'm not wealthy enough for their expensive fees).
I've done this:
Created a database as read/write, using Neo4j Desktop (v1.1.8) under Mac and 3.4.5 as database engine.
Populated it with just a few nodes
Stopped, set dbms.read_only=true and restarted
At the last step, the server logs shows the error: "UnsupportedOperationException: Can't create index writer in read only mode" and shuts down. So, is that option really (still) working?
Neo4j Desktop is meant for usage with Enterprise Edition (you do get an individual license for usage for dev purposes only), not Community Edition.
I believe there's an issue with dbms.read_only=true and running via Neo4j Desktop, but there isn't any problem using the server deployment of Neo4j Community edition and using that setting.
My advice would be to download the community edition from Neo4j and use that directly rather than going through Neo4j Desktop.
Following on from the information found in the blog post titled 'Neo4j 2.1.2 – Maintenance Release', I thought I should check the consistency of a database that has been upgraded to Neo4j 2.1.1.
My set up: Neo4j community edition running on Windows Server 2012 R2 - the binary distribution running as a Windows service (NOT the windows desktop launcher executable).
In the blog post it talks about using the backup tool included with the enterprise version of Neo4j so I have downloaded an evaluation copy (2.1.4) so have access to Neo4jBackup.bat. I cannot however, get a backup to run. No matter what I try I get
Couldn't connect to '127.0.0.1:6362'
or a variation thereof.
I am running
.\bin\Neo4jBackup.bat -from localhost -to D:\DataBackups\Neo4j\check
I have tried specifying a port, specifying IP address, using single://localhost. After consulting the manual more closely I have also amended my config to add
# Enable online backups to be taken from this database.
online_backup_enabled=true
# Port to listen to for incoming backup requests.
online_backup_server=127.0.0.1:6362
Still I receive the same error. I am clearly being a moron. What am I doing wrong? Help!
The question boils down to 'how do I back up a community edition database as alluded to in this Neo4j blog post?
OK so yes. I am a moron. It just came to me. You need to open the database with the enterprise edition!
For anyone who is overcome with a moment of stupidity, like me
Copy the database you wish to check (graph.db by default) to the data directory of your evaluation copy of Neo4j
Start up Neo4j (you may or may not need a store upgrade)
Run .\bin\Neo4jBackup.bat -from localhost -to [your desired backup location]
Sit back and await the results
Feel free to mock/throw rotten vegetables etc at me....! :)
Starting with the 2.1 line (somewhere around 2.1.5 I think) the consistency checker was moved from the enterprise edition to the community edition. It is therefore now possible to check a DB with the community edition too. In the root of the neo4j server directory run:
java -cp 'lib/*' org.neo4j.consistency.ConsistencyCheckTool data/graph.db
Note that this is not an offical API (it's undocumented).
I am a developer at a company. We started using Neo4j recently. We have been using Neo4j community editions till now. We use Amazon as our cloud. We put up the neo database onto cloud and we are using ubuntu instance for this. I was able to put Neo4j community editions onto the cloud till now and put data on it. We have now bought the enterprise edition of Neo4j (Neo4j Enterprise edition 2.0.0) . I am trying to put the new enterprise edition onto the cloud using ubuntu.
I have downloaded the enterprise version and extracted the contents of it on ubuntu. Now I am trying to install Neo database using the command:
var/lib/neo4j/ neo4j-community-2.0.0 $ sudo ./bin/neo4j-installer install
This gives me output as:
WARNING: this installer is deprecated and may not be the optimal way to install Neo4j on your system.
Please see the Neo4j Manual for up to date information on installing Neo4j.
Press any key to continue
Graph-like power should be handled carefully. What user should run Neo4j? [neo4j] ubuntu
ln: failed to create symbolic link ‘/etc/init.d/neo4j-service’: File exists
update-rc.d: /etc/init.d/neo4j-service: file does not exist
This does not install neo database now. The same command was working fine with Neo4j community editions. Please let me know what should be done for this? I am stuck on this for several hours now. I have no clue what should be done.
Any help would be greatly appreciated. Please help.
Thanks in advance.
As you are a customer, probably best to open a support ticket, and then add an answer here, so that other people can learn about it?
Did you remove the community installation first? It could be a clash of the two versions.
Because the manual actually says the same thing here:
