EMFStore with MySQL instead of MongoDB [message #1299869]

Hello There

I was wondering if there is a possibility to configure EMFStore with
MySQL instead of default MongoDB

Any help in that area would be appreciated.

Regards
Malai

Hi,

currently we only support xmi-files and MongoDB as storage.

However by using the org.eclipse.emf.emfstore.server.resourceSetProvider / .client.resourceSetProvider extension points you can add your own storage solution based on the EMF resource abstraction.
For MySQL storage you can take a look at Teneo (https://wiki.eclipse.org/Teneo/Hibernate , https://wiki.eclipse.org/Teneo/Hibernate/EMF_Resource) and try to integrate it with EMFStore.
For this you need to implement the ESResourceSetProvider interface and pass a ResourceSet to EMFStore that will create HibernateXMLResources and has an URIConverter that will map the URIs used by EMFStore to URIs expected by Teneo.
You can take a look at the emfstore.mongodb-plugins to see how this can be done. Oh, and this would make a nice contribution Smile

I hope this will help

Cheers
Johannes

Hi

I tried to figure out the MongoDB Support. But was unable to find the
same. Do i need to download seperate plugins for MongoDB or do i get it
has part of the basic installation.

Looking for more pointers. Will definitely be happy to contribute :)

Hi,

you can find guidelines on how to get the source code and setup the IDE here: http://eclipse.org/emfstore/gettinginvolved.html
The mongodb plugins are prefixed org.eclipse.emf.emfstore.mongodb.*

The mongoDB feature is not part of the default installation, but is available on the update site under "EMFStore Additional Features".

Hello Johannes

Thanks for your reply. I have checkedout the MongoDB feature. It wasnt
part of the Default Installation as written by you. Now i am even more
curious.

I have been evaluating ECP and when i run ECP with EMFStore Repository
plugins doesnt it share them on MongoDB. How does ECP them share its
project using EMFStore, does it use XMI Resource sharing on Workspace or
based on Local History.

Now i am a bit confused. I run the sample ECP Application with EMFStore
and connect to EMFStore using the Model Repositories. It starts the
EMFStore server in the background. But this doesnt start MongoDB and
using XMI based Sharing. Is my understanding rite ??

For starting with MongoDB i need these MongoDB Plugins.

Regards
Malai

Hi,

if you haven't included the EMFStore mongodb plugins in your run-configuration the projects will be stored as XMI in your user-home directory in the .emfstore -folder.
In order to store them with mongodb you will have to add the EMFStore mongodb plugins to your runconfig and their dependencies. Those are:
org.eclipselabs.emf.query.simple
org.eclipselabs.mongo
org.eclipselabs.mongo.emf
org.eclipselabs.mongo.emf.builders
org.eclipselabs.mongo.emf.converter
org.eclipselabs.mongo.emf.ext
org.eclipselabs.mongo.emf.query.simple
org.eclipselabs.mongo.emf.streams
org.eclipse.equinox.ds
org.eclipse.equinox.cm
Also make sure that equinox.ds and *.cm have autostart set to true and a start-level of 1.
If you are missing those dependencies in your target platform, take at look at the emfstore.target.
EMFStore expects that there is a running mongodb instance it can connect to. By default it will look for an instance running on the localhost.

Cheers
Johannes
