Context info: I'm just trying to write some documentation about how to get the most out of ArcGIS Online Hosted Feature Servicesand I have some questions I'd need a little help with. I following this workflow to join two layers and save them as a layer view. Trying to do some reverse engineering using Postman and I have found seven POST requests are made during this process (Postman collection with those requests). I have explored these requests and I have some questions: I have seen the first two requests are createService and addToDefinition, specifying "isView: true" and updating the service definition (view SD) to specify information about the query parameters themselves. Is this enough to have a layer view fully functional?? The third request updates the item "properties" field with a JSON that includes a "jobUrl" set to: "https://analysis7.arcgis.com/arcgis/rest/services/tasks/GPServer/JoinFeatures/jobs/ViewJob_1570094204566", When was this job created?, I have filtered my browser network tab by "/JoinFeatures/submitJob" and I haven't found any request.  Is this necessary? I make sense ... but I'm confused because I can't find when it is sent. Fourth request is adding a JSON to the item's static resources with the name of the tool and parameters needed to run that tool (in this case: Join features) Is this necessary for something? Request 5, 6 and 7 are just update item metadata, thumbnail, tags, etc I assume all these are optional too Any help is more than welcome . Thanks in advance, Raul ... View more

Requirement: I want/need to do this using hosted feature services in ArcGIS Online I'm just trying to do something like this with just one REST API call: SELECT table1.* FROM table1, table2 WHERE table1.primary_key = table2.foreign_key AND table1.attr = 'Value1' AND table2.attr = 'Value2' ‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍ Now I'm going to explain the approach I have been following and the issue I'm facing, but maybe the approach is wrong. Steps: I created a file geodatabase in ArcGIS Pro with two Feature Classes (table1 & table2) I created a relationship class where: table1.primary_key = table2.foreign_key I published it in ArcGIS Online Then I tried to do a similar query to this one using the query related records end point from the REST API but I couldn't: First, I noticed that it is not possible to set the objectIds param to "*" (which I don't quite understand why) <- but I could manage it by setting all the objectIds manually. But the real problem I found was that in the definitionExpression param I could only use attributes from one table/layer (the related one) but not from both of them. So, I'm not sure if the only way to solve this is programmatically by: First query one table to get only the OBJECTIDs that meet all the criteria established to this table And then use the query related records setting the objectIds to those I recovered in step 1 and set the definitionExpression to add the pending criteria (the one to filter also the data within the related table). Is this the way to solve what I'm trying to achieve or there's some way to do it with just one API request?. Best regards, Raul BTW: I also tried doing a JOIN in memory and then selecting features by attributes and it worked in ArcGIS Pro, but I couldn't publish that on ArcGIS Online ... View more

From this question we realized that the StreamLayer documentation explained that the following could be done: You may also use your own web socket server, as long as it emits geographic features in the Esri JSON format. So Jorge Barrachina Gutiérrez and I are just doing an experiment to connect a StreamLayer with a custom websocket server (built with NodeJS) and it's working in JS API 3.x & 4.x except in versions >= 4.9. We noticed in this version (4.9) the StreamLayer was updated, so we guess something might be broken because to our understanding the changes shouldn't affect to the behaviour of this example. I have recorded a video to show you the issue: Does anyone have any idea what might be going on? In case you look the source code you can find it on this repo on Github. // cc: John Grayson John Gravois Gavin Rehkemper Sean McGee‌ Max Payson‌ Rene Rubalcava ‌ --- By the way..., sorry for not been at the DevSummit in Palm Springs! :___(, hopefully we'll see some of you at the DevSummit Europe this year! ...
