Returning large size feature set

MichaelGinzburg — Thu, 22 Nov 2012 11:33:55 GMT

Hello!

I want to implement a Silverlight query task which is to return quite large feature set (several hundreds of features).
What is the best way? Is API able to carry such a large feature set? Or should I fetch them in portions (say, 1000 features every time)?

Thanks,
Michael

In my experience, there should not be any problem in getting huge number of result features. I used to get approx. 1500 features in one of my projects and I did not face any problem. Just, rendering this number of features in a graphics layers took a bit of time.

Thanks, sanjayjadhav

However, I might have to return about 150000 features. Will it work?

I might be mistaken, but I think there is a max JSON length that can be sent from the server to the client. I don't know it off hand (Google will probably tell you). If you return too many features your JSON String might get truncated resulting in an error.
