Very nice project! I was hoping to get some more details about the openstreetmaps implementation. Specifically: * importer: Is the importer custom to this package, or using an existing library? What is the performance of that import process for the world pbf, compared to `Osm2pgsql`, `Osmium`, `Osmosis` and `Imposm`. * data structure: It sounds like this is a full import? That it maintains all nodes, ways and relations? * normalization: `In order to save denormalized geometries in PostGIS (e.g. linestring, polygon, multi-polygon, etc.), Baremaps creates a cache for nodes, ways and relations. [LMDB](https://symas.com/lmdb/) is used under the hood to achieve great performance.` It sounds like this normalization is happening in the server and not in postgres. What is the performance impact of this normalization? Is there a `cache warming` period on server restart? * updating: Any plans on supporting periodic updates from OSM changesets from something like `osmupdate`? * caching: It appears to me like the server is caching tiles. It would be helpful to know how that caching is happening, what are the space requirements, and how one would purge tiles from cache (especially after a changeset has been imported). -- This is an automated message from the Apache Git Service.
