Is there any way to force a featurelayer to never generalize and/or quantize the geometries in the layer? I am asking because I'm doing a lot of geometryengine operations on a featurelayer and sometimes I get tiny slivers as output from the engine. Seemingly this is caused by tiny differences in the geometries depending on zoom level etc. In version 3 of the api we had setMaxAllowableOffset and autoGeneralize props as means to control this but in version 4 I cannot find it.

Thank you.
As far as I know, the same approach mentioned above would work. Can you add a link to the ESRI documentation you mentioned?
Joel, question how we could address this same issues with an internal ArcGIS Server 10.9.1 hosted featurelayer. Thank you for any input you may have.
ESRI states:
Known Limitations
Only supported with ArcGIS Online hosted services or ArcGIS Enterprise 10.6.1 services.
There doesn't appear to be a means of disabling the quantization via layer settings, but using a RequestInterceptor to remove the quantizationParameters from the queries to the server should work for most common implementations:
var featureLayer = new FeatureLayer({ url: "https://server/path/etc/FeatureServer/0" }); esriConfig.request.interceptors.push({ url: featureLayer.url + "/" + featureLayer.layerId + "/query", before: function (params) { if (params.requestOptions.query.quantizationParameters) delete params.requestOptions.query.quantizationParameters; } }); map.add(featureLayer);
