Currently I am using the query task when dealing with a small set of datapoints (less than 500) and I am using a dynamic layer (over the top of a cached layer) which I query with Identify task when dealing with a large set of data points. Is this the correct choices to make in each situation?</SPAN><BR /><BR /><SPAN>Thanks for the help</SPAN></BODY></HTML> Sun, 19 Dec 2010 16:50:28 GMT https://community.esri.com/t5/arcgis-javascript-maps-sdk-questions/querytaks-vs-identify-task/m-p/448478#M41439 GavinTrowles 2010-12-19T16:50:28Z Re: QueryTaks vs Identify Task https://community.esri.com/t5/arcgis-javascript-maps-sdk-questions/querytaks-vs-identify-task/m-p/448479#M41440 <HTML><HEAD></HEAD><BODY><SPAN>I believe I read somewhere in the&nbsp; "JavaScript API Concepts" tabs&nbsp; that one advantage of the Identify Task is that it can be used against multiple operational layers.</SPAN><BR /><SPAN>The Query Task can only be used against one operational layer.</SPAN><BR /><SPAN>Also, you need to consider performance concerns.&nbsp; </SPAN><BR /><A href="http://help.arcgis.com/en/webapi/javascript/arcgis/help/jshelp_start.htm">http://help.arcgis.com/en/webapi/javascript/arcgis/help/jshelp_start.htm</A></BODY></HTML> Mon, 20 Dec 2010 13:34:33 GMT https://community.esri.com/t5/arcgis-javascript-maps-sdk-questions/querytaks-vs-identify-task/m-p/448479#M41440 K_DRex 2010-12-20T13:34:33Z
