Right way to use supercluster with dynamic data about supercluster

[Steve7394]

is there any suggestion? this is useful for some fleet management system

@Steve7394 I've been waiting for 5 months for some kind of reply... 😞

Sorry for the late reply.

• In theory, it shouldn't matter whether you recreate the Supercluster instance or use load — in both cases, the amount of work will be the same.
• I don't think there any way to know whether a cluster exists on a specific zoom before clustering completes.
• You can reuse the same points array if you wish, modifying it and the reloading/recreating the index. I don't know whether there's any opportunity for caching beyond that.

Supercluster in general isn't very well suited to dynamic cases. It was designed from the ground up for static cases. It may work well in specific cases still, but I don't think any improvements can be made for that category of cases.

Ok thank you @mourner . Any suggestion for some library more suited for this use case?

I came across this question after finding we had a memory leak in our application due to calling load repeatedly on a single Supercluster instance.

This leak went away when we recreated a new Supercluster each time prior to calling load. Using v8.0.1.

Have not had a chance to dig into this further.
