HI Jens,
Sorry for the confusion.
If you check my second post you will notice the code which I use I will
paste it here again.
var view = _database.CreateAllDocumentsQuery();
var docs = view.Run().Select(x => new DatabaseUtils.
CacheData
{
DescrName = (string) x.Document.Properties["name"],
Date = Convert.ToInt32(x.Document.Properties["date"]),
DescriptionType = Convert.ToInt32(x.Document.Properties[
"type"]),
Version = (string) x.Document.Properties["version"]
});
_iterator = docs.GetEnumerator();
so I actually use _database.CreateAllDocumentsQuery();
but the name of variable I choose is wrong. I kept it as "view" which
probably cause the confusion.
And the view creation code which I posted earlier
view.SetMapReduce((
IDictionary<string, object> document, EmitDelegate emitter) => {
if (document["_id"] != null) {
emitter(document["_id"], document["_id"]);
}
this one is old code and I don use it.
But the point is that even though I use _database.CreateAllDocumentsQuery();
its dead slow.
Just to give more info the database which I am querying has about 10000
documents and some of the document size is more than 90MB. Is that the
reason of it being slow?
But what I wanted is just few properties of the document but not full
document.
Once again sorry for the confusion.
