Adding multiple cloned layers

[Psijic]

I didn't find in the code (not sure) if duplicated layers will not be added to the map layers. Like

val markerLayer = ItemizedLayer(mMap, markers, markerRendererFactory, listener)
repeat(10) {mMap.layers().add(markerLayer)}

adds markerLayer only once and there is no need to such observes. Vtm uses Set for it or something alike, right? (Not sure it will work this way because ItemizedLayer is not a data class).
Otherwise it should be manually restricted in Composables.

You can check the various samples.
They have examples where many layers are created in a loop and added on the map.

Suppose, their layers were different. I could clone and repeat 1000 layers for performance test but not sure it solve the problem of duplicating even if performance is ok.

[devemux86]

The procedure is to create and add many layers (e.g. PathOverlayActivity).
For layers that host multiple items, create one or many layers and fill them with items (e.g. MarkerOverlayActivity, VectorLayerActivity).

The case is next: geohash is used to show only current map position POI markers. If I remove and add a new layer - I see blinks. If I don't remove the layer - markers duplicates or their count grows as much to hit the performance.
