Load annotations as needed #494

Open GoogleCodeExporter opened 8 years ago

GoogleCodeExporter commented 8 years ago
Describe new functionality:
Some of our datasets are quite long in duration and thus many annotations may 
be generated. Currently, it looks like all annotations are loaded when a 
dataset is opened, which is problematic if there are many annotations or if the 
browser cache is small (correct me if I'm wrong). Also, I hesitate to add more 
annotations as it hinders the performance of the online viewer.

It would be great if a better way to handle the annotations can be designed. 
Perhaps load the start times on the initial load to display on the bottom 
timeline, and then load the rest of the annotation and display them dynamically 
if the user is viewing relevant times.
