Hi, Thanks for the quick reply, What activities do we need to support in 
addition to document ingestion and document deletion,

And also I've seen that MongoDB is a NoSQL type of document-oriented database 
programme also I've seen few other implementations of OutputConnector interface 
such as KafKaConnector and GTSConnector can I use any of those implementations 
as a reference for my implementation or does MongoDB has no relevance to all 
those implementations other than extending the similar interface, can you 
please suggest a good reference implementation that would make me understand 
the task quickly if there is any.

Hi, Piergiorgio Lucidi, 

I went through your presentation and Shinichiro Abe's presentation, from that I 
figured that there are 3 types of connectors

1.Repository Connectors

2.Authority Connectors

3.Output Connectors.

and that I have to write a repository connector for MongoDB please correct me 
If I am wrong

Thanks, Piergiorgio!

I too am way too overcommitted to mentor this year, so I'm glad you are
doing it.  Thanks again!

Thanks for the update!  We'll recommend that action the next time somebody

Thank you Rafa and it seems that we have a guy that would like to implement
the new MongoDB Output Connector:

I will help him to start the development.

Thanks Karl. Finally figured out the solution. I had to change the default 
locale configuration for linux. I edited /etc/sysconfig/i18n and changed 
LANG="en_US.ISO8859". Now it is picking those files.
