Updating CZML without refreshing page

Hello, is there any way for generating CZML with API calls from a dynamically updated database without refreshing page for real time visualization project?

Thank you.

Welcome to the Cesium community! You can add/remove CZML data sources at runtime, this example does that: https://sandcastle.cesium.com/index.html?src=CZML.html.

What kind of project are you working on?
