What are the valid Connection.add options?

Are the options documented somewhere ?

The reason I ask is because I want to do is set an option that will ensure the document is persisted to disk before returning. What I did was set the persist_to option to a number >=1. I think that should do it, but I just want to confirm that is the correct option.

* Like {@linkcode Connection#set} but will fail if the key already exists.
* @param {string} key
* @param {string|object|Buffer} value
* @param {object=} options
* @param {integer} options.expiry
* @param {integer} options.flags
* @param {string|integer} options.format
* @param {integer} options.persist_to
* @param {integer} options.replicate_to
* @param {KeyCallback} callback
* @see Connection#set
* @see Connection#addMulti
Connection.prototype.add = function(key, value, options, callback) {
this._invokeStorage(this._cb.addMulti, arguments);

« Back to question.


So the important options/parameters are:
- expiry : time to live (TTL),time before the key/document is deleted from Couchbase
- flags : usually something internal you should not need it
- Format : Used to set the format of the value you want to save see http://www.couchbase.com/autodocs/couchbase-node-client-1.2.0/global.html
- persist_to : durability constraints, that check if the document has been saved to disk on x nodes
- replicate_to : durability constraints, that check if the document has been replicated, in memory on x nodes

Note the durability constraints, do not "force" the write, just allow you to check if this is done, see http://docs.couchbase.com/couchbase-devguide-2.2/#monitoring-data-using-...
