Caching SuperCluster Index #218
Description
Hi, is it possible to cache index generated by SuperCluster so that I can use it next time instead of calling new Supercluster({}).load() Again?
The code below takes time for large records. I am trying to get over this issue.
superclusterIndex = new Supercluster({
map: (props) => props,
radius: MapConfig.clusterRadius,
maxZoom: ClusterZoomLevel.maxZoom,
}).load(geoJsonData.features);

What do you mean by caching? You could simply save it into a singleton variable or whatever and use it as you need it.

@Enkosz More like I wanted it to persist even after killing the app. So that I don't have to generate superClusterIndex again. The data I am handling is big like close to 70000 records. I was checking if I can save it in some storage so that each time user opens the app after killing, the indices generated are available.

I'm wondering the same. My use case: running on servers behind a load balancer, with multiple sessions each clustering their own set of data. Each session is for a group of users that want to see the same clusters but may be hitting different servers. So I'm wondering if it's feasible to serialize the index and persist to a DB.
