Explore other Mosaic Backends (DB)

[vincentsarago]

DynamoDB backend is really interesting because it enables large-scale mosaic and with the latest changes we can even store a lot of mosaics in a single table.

As Mosaic become more popular (at least on my side 😄) I'll need to explore other DB backends for other cloud providers (e,g Azure Cosmos)

I'm also thinking about read only backends.

By read only I'm mean, we could connect cogeo-mosaic backends to spatial database (or spatial index). Those won't have to have all MosaicJSON implementation but we could just use get_assets to do the spatial query.

with RTreeBackend("spatial_index.r") as mosaic:
    mosaic.assets_for_tile(1,2,3)
    mosaic.assets_for_point(lng, lat)

Permitting read-only backends could allow you to make a read-only adapter to query a postgres-backed STAC API...
