![]() ![]() With the grid-based approach, envelopes for the desired area are created behind the scenes. This data utilizes the grid-based design which is what we want. ![]() Version 1.2.2 adds new capabilities like the "Generate Query Extents" tool which will be a great help for generating feature service test data. To tackle such a task, it is highly recommended to use the very excellent Load Testing Tools. This test will require some good test data to use within the JMeter test. To create a service from this data, see Publish hosted feature layers in ArcGIS Enterprise. #Apache jmeter logo pro#This data will be published from ArcGIS Pro to a hosted feature service in ArcGIS Enterprise or loaded directly through Portal for ArcGIS. Large scale view with labeling enabled:.It is provided through the Creative Commons (CC0) license. The 179K polyline records of USGS Roads data in WGS 1984 Web Mercator (Auxiliary_Sphere), equates to about 200MB when zipped. The spatial size of the data source also needs to be large enough to generate decent test data but not too big where it is cumbersome to download.Įnter in the Motor Vehicle Use Map: Roads feature layer dataset on . But this repeatability requires access to the same set of data. The understanding of the process in this Article is most effective if the steps can be reproduced. #Apache jmeter logo how to#How to Test a Hosted Feature Service? The USGS Motor Vehicle Use Roads Dataset Couple this with the fact that each query request in the transaction will have a unique geometry and changing maxAllowableOffset (depending on the map scale) and its a lot of moving parts to keep track of. ![]() To repeat this behavior, the constructed load test will not have just one request to issue but many and a varying amount. A navigational "pan" or a "zoom" in the web browser produces a handful of different queries, each with their own geometry. Hosted Feature Layer Service Testing ChallengesĬompared to testing the export map function, testing Hosted Feature Layer Service queries is challenge as the requests are more complex to achieve programmatically. Given that hosted feature services are a proven and favorite service technology, it makes sense to want to test feature queries under load to observe its scalability first hand. Couple this with client-side rendering of the data returned and its a win-win. Additionally, querying these layers are based on a "repeated" grid design which can help provide a higher degree of scalability over other visualization technologies. However, Hosted (feature) layers are also a popular capability of ArcGIS Enterprise and are widely used in deployments.
