How to GET a complete class from parse.com

Im currenlty trying out parse.com to use it as a repository for sensor messages. I do some data science with those messages using python but when trying to GET the class where I have the entries I can only GET a maximum of 1000. I though a possibility would be to run a job that export all the entries to a csv or json, can that be done on the cloud code platform?

You can simply use query.skip(10000) code to get more but skip cannot be larger than 10000.

Or you can use this simple code to export entire class

Queries provide skip, so the nice way to do this in cloud/JS is to chain promises recursively, skipping the count of objects already retrieved: 

function unboundedQuery(query, array) {
    array = array || [];
    query.limit(1000);
    query.skip(array.length);
    return query.find().then(function(results) {
        array.push(results);
        return (results.length == 1000)? runQuery(query, array) : array;
    });
}

Call it like this:

var query = new Parse.query("Class");
// qualify, sort, etc, but no need to set limit or skip
unboundedQuery(query).then(function(results) {
    // results will contain all objects in "Class", unless it timed out
});
