Hmm ok then I should try with View but one thing I don understand how to
emit multiple properties?
Is it like this?
view.SetMapReduce((IDictionary<string, object> document, EmitDelegate
emitter) => {
emitter(document["_id"], document["_id"]);
emitter(document["version"], document["version"]);
emitter(document["type"], document["type"]);
}, null, "1");
And regarding 90Mb data. Hmm yeah the data is huge I can't help it but hmm
yeah I have been storing it like JSON data. Infact I can try using
attachments.
I am using couchdb with lite so that I can store huge data.
So that means attachment is treated somehow differently?
