Working with TileSet
Use tile services protocols such as WMTS for detailed vector datasets which do not change frequently.
-
Optimize the tile cache storage and retention policy to limit disk space.
-
Tiles at high scales are usually very quick to render (not very many features), but can consume a considerable amount of disk space the more zoom-levels are stored.
-
GeoServer can be configured to define a TileSet for zoom levels 1-9, but only store tiles for zoom levels 1-6.
When working with a zoom level that is not stored GeoServer will render each tile on demand; however downstream proxy caches and browser caches will respect that a consist URL is used for each tile and manage their own cache respecting the cache retention settings you have defined.
