Hi,

is the river tracking updates on documents inside mongodb as well?

I don't know if I'm missing something, but I can't get this to work.

I've set up an replica with just 1 node for test purposes.
Installed the river just like in docs stated.
Add an document to mongodb

But, nothing happens?
I don't see any exceptions or anything that would show a failure.

I'm using Java API to set up the river:
this.esNode = NodeBuilder.nodeBuilder()
.settings(ImmutableSettings.settingsBuilder().put("gateway.type",
"local")).node();

	// mongodb river index
	XContentBuilder json;
	try {
		json = jsonBuilder()
				.startObject()
					.field("type", "mongodb")
					.field("mongodb").startObject()
						.field("db", "test")
						.field("collection", "test")
					.endObject()
					.field("index").startObject()
						.field("name", "testname")
						.field("type", "testtype")
					.endObject()
				.endObject();

		this.esNode.client().prepareIndex("_river", "mongodb",

"_meta").setSource(json).execute();

Ok, my bad.
I've switched to ES RC1 while the plugin was still using 0.18.5.
So I've updated all the changes and now everything seems to work.

Thanks for the river

@Richard

seems like partial updates, like increment are not supported now?
Logs on this

Cannot get object id. Skip the current item: [{$set={ "userLikesCount" : 1}, _id=null}]
Oplog do not contain _id inside "o", but there is "o2" which contains
the _id of the document.

Do you think you could fix this?
Thanks

awesome! I'm excited to stop using my homerolled oplog follower
(GitHub - orenmazor/elastic-search-loves-mongo …slightly out of
date now).

can I use this to give weight to different ops? my current problem is that
my delete and index activity is pretty equally high, and I'd like to
prioritze indexing over delete (i.e. I'm currently modifying my oplog
follower to have an internal queue with qos)
