Question

I have a query for the Rally Analytics which returns a data set larger than the pagesize. So I want to do another query to return the remainder data set. I tried setting a startindex value but that does not work, StartIndex stays at 0.

                    this.query = {
                        find:Ext.encode(requestedQuery.find),
                        StartIndex:20000,
                        pagesize:20000 //MAX_PAGESIZE
                    };

                _queryAnalyticsApi:function () {
                    Ext.Ajax.request({
                        url:"https://rally1.rallydev.com/analytics/1.27/" + this.workspace + "/artifact/snapshot/query.js?" + Ext.Object.toQueryString(this.query) +
                            "&fields=" + JSON.stringify(this.requestedFields) + "&sort={_ValidFrom:1}",
                        method:"GET",
                        //need to change this to a POST
                        success:function (response) {
                            this._afterQueryReturned(JSON.parse(response.responseText));
                        },
                        scope:this
                    });
                },

The parameter you’ll want to use is called start. Also, on subsequent pages it is important to include a filter using the ETLDate returned from the first page of data so your results are consistent in time. We have created a SnapshotStore in the AppSDK 2.0 that handles all this complexity for you. Look for it soon!
