35. Esri UC 2014 | Technical Workshop | When do I use dynamic layers instead of feature layers on the client for thematic mapping? - large number of features - complex geometries that cannot be generalized - when it provides a performance advantage Each approach has tradeoffs - e.g. Client side features scale better and provide more interactive behavior GenerateRenderer operation can be used with both approaches Dynamic layers vs Client-side graphics Best Practices for Designing Effective Map Services
