Arcgis Javascript API for query tasks on tiled map service

DharmaRajan

I'm using ArcGIS Javascript API 3.17 to view my point data from ArcGIS server 10.3. Initially I have published the point data as dynamic map service but it is taking too long time to render the data over web as my feature class has around 80,000 point features. So I've changed dynamic map service to tiled map service and generated the cache. Now it is rendering too fast from cached tiles. Now the issue is that I have to perform Query task on my data. For that I have few questions:

Is it require to add dynamic map service also under tiled service in the map to perform the query tasks? Or only passing dynamic map service URL to query task is enough? If so, How can we show the result features on map?

Please suggest me.

And the results of the Query/Identify Task can be added to the map as part of a Graphics Layer (GraphicsLayer | API Reference | ArcGIS API for JavaScript 3.17 )

Thanks

You can do a normal Query Task (QueryTask | API Reference | ArcGIS API for JavaScript 3.17 ) or IdentifyTask (IdentifyTask | API Reference | ArcGIS API for JavaScript 3.17 ) on the REST endpoint of the cached service..
