Where is threshold for cluster strategy in openlayers 3?

Question

In openlayers 2.8 there was a threshold associated with the cluster strategy as per ticket https://trac.osgeo.org/openlayers/ticket/1815.

In openlayers 3 there is no mention of it anywhere (and the strategy paradigm seems to be gone as well). http://openlayers.org/en/master/apidoc/ol.source.Cluster.html

Does anyone know if there exist a ticket for this feature?

Answer 1

The paradigm has changed considerably. In OpenLayers 3 you create a new layer, with a cluster style, and the "threshold" is set as a maxResolution, or minResolution in the layer's options. Similar to:

var clusterLayer = new ol.layer.Vector({
                visible: true,
                zIndex: insightMap.totalServcies - element.SortOrder,
                id: Id,                                           
                serviceId: element.Id,
                minResolution: clusteringThreshold,
                cluster: true,
            });

You can also use minZoom and maxZoom according to the documentaiton, but I've encountered issues with them performing consistently.
