Irindu Nugawela commented on CONNECTORS-1490:
---------------------------------------------
Hi All, I faced an issue during development, the MongodbOutputConnector, and
GridFSRepository Connector both share a common dependency mongo-java-driver and
GridFSRepositoryConnector uses mongo-java-driver version 2.11.3 while the
latest stable is version 3.7, add to that mongo-java-driver version 2.x does
not support mongod server versions 3.x methods like
{color:#353833}[authenticate|http://api.mongodb.com/java/2.13/com/mongodb/DB.html#authenticate-java.lang.String-char:A-]([String|http://download.oracle.com/javase/1.5.0/docs/api/java/lang/String.html?is-external=true]
username, char[] password) works only against mongod server versions 2.x and
they are deprecated on mongo-java-driver version 3.x {color}
{color:#353833}I cannot use the latest stable mongo-java-driver version 3.7 for
development because GridFS Connector uses the older version and the older
mongo-java-driver version 2.11.3 is already in classpath. I can continue
development mongo-java-driver version 2.11.3 but the MongodbOutputConnector
would not support the newer mongodb servers (version 3.x).{color}
{color:#353833}Also I've noticed that GridFS Connector uses
[authenticate|http://api.mongodb.com/java/2.13/com/mongodb/DB.html#authenticate-java.lang.String-char:A-]([String|http://download.oracle.com/javase/1.5.0/docs/api/java/lang/String.html?is-external=true]
username, char[] password) method also classes DBTCPConnector which are
deprecated from mongo-java-driver version 3.x which would also make GridFS
connector not work as expected with newer mongodb servers (version 3.x).{color}
{color:#353833}There are significant differences with mongo-java-driver version
2.X and version 3.X{color}
{color:#353833} {color}
> GSOC: MongoDB Output Connector
> ------------------------------
>
> Key: CONNECTORS-1490
> URL: https://issues.apache.org/jira/browse/CONNECTORS-1490
> Project: ManifoldCF
> Issue Type: New Feature
> Components: MongoDB Output Connector
> Reporter: Piergiorgio Lucidi
> Assignee: Piergiorgio Lucidi
> Priority: Major
> Labels: MongoDB, gsoc2018, java, junit
> Original Estimate: 480h
> Remaining Estimate: 480h
>
> This is a project idea for [Google Summer of
> Code|https://summerofcode.withgoogle.com/] (GSOC).
> To discuss this or other ideas with your potential mentor from the Apache
> ManifoldCF project, sign up and post to the dev@manifoldcf.apache.org list,
> including "[GSOC]" in the subject. You may also comment on this Jira issue if
> you have created an account.
> We would like to extend the Content Migration capabilities adding MongoDB /
> GridFS as a new output connector for importing contents from one or more
> repositories supported by ManifoldCF. In this way we will help developers on
> migrating contents from different data sources on MongoDB.
> You will be involved in the development of the following tasks, you will
> learn how to:
> * Write the connector implementation
> * Implement unit tests
> * Build all the integration tests for testing the connector inside the
> framework
> * Write the documentation for this connector
> We have a complete documentation on how to implement an Output Connector:
> [https://manifoldcf.apache.org/release/release-2.9.1/en_US/writing-output-connectors.html]
> Take a look also at our book to understand better the framework and how to
> implement connectors:
> [https://github.com/DaddyWri/manifoldcfinaction/tree/master/pdfs]
