New Mongo Input component question - Mongo in general

Hi,

I was taking a look at the new mongo input (PDI 5.0.1) and from what I had read it was supposed to make it easier to get a list of fields within the Mongo record.

I only seem to be able to output a single JSON field. This does not really solve anything for me because I either have to type in the field list in the JSON input or run it through a script.

I can connect to my Mongo source just fine and I have a query expression :-

{ $query : { $or : [{ rating.addedTimestamp : { $gte : 1385253746 }},{ rating.updatedTimestamp : { $gte : 1385253746 }} ]}}

Am I missing something? The documentation suggests it should be able to read the schema.

Are my expectations too high?

There just seems to be no tool that makes reporting from Mongo easy - not being able do joins is a big issue for me. If someone knows of a good tutorial - please let me know. The pentaho example are too simplistic and report aggregate values. We still have great need to report details.

Thanks,
