Tristan Morris updated NIFI-2135:
---------------------------------
Attachment: nifi-mongodb-nar-0.7.0.nar
0001-NIFI-2135-PutMongo-will-now-update-using-a-set-and-r.patch
Updates to the PutMongo processor to handle the following cases:
Insert - It'll just insert the FlowFile (JSON) as is.
Update - It'll now perform a $set with the contents of the FlowFile, and also
an upsert. If the record is present then it'll be updated (attributes which are
already in the database will stay), and if the record isn't present (and upsert
is true) then it'll be inserted.
Replace - It'll 'overwrite' if it's in the database, or insert if upsert is
true.
Apologies the tests aren't also updated.. I did brief battle as the test was
being Skipped, then quickly gave up. Additional apologies as I'm sure there are
problems/rule violations using the code as is.
There are a bunch of other things to add to the PutMongo processor. So if I get
the tests fixed then I'll add some more stuff.
The patch will also work with master/1.0.0.

> How can I use put mongo processor to add a new key value pair to an existing
> document? The flow file contains the document object Id. I have set 'mode'
> property to 'update' and 'upsert' property to false and 'update query key'
> property to '_id'. Flow file content is something like this.
> {
> _id:ObjectId(577216f0154b943fe8068079)
> expired:true
> }
> Without inserting the 'expired:true', it replaces the whole document with the
> given one. So is there a way to insert the new key value pair to collection
> without replacing the whole collection in MongoDB using putmongo processor?
