What is map cache-mapcache
Cache: As the name implies, it stores the required data in the cache to improve data access efficiency.
The map cache also stores the images that appear during the editing, tagging, scaling, and translation processes in the cache temporarily. The images are stored as images. Each time we perform the same operation, the View window calls the cached image instead of refreshing the map data immediately. The cached existing image is returned to the View window in time to complete the corresponding operations, this greatly improves the display efficiency of the view.
!!!! Note: Only data in the spatial database can be cached. the shape and coverage files cannot be cached.
When will cache be used?
Generally, mapcache is not required. The cache mechanism should be used in the following situations:
1. When you do not need to edit a large amount of data.
2. You need to define a query for a specified region.
3. cache is often used in network data. It is also useful when editing a large number of nodes.
Disadvantages of using mapcache:
The cache must occupy a certain amount of memory. Therefore, we must pay attention to the memory when using the map cache. Because it also consumes a certain amount of memory.
How to Use mapcache:
1. Use the "build map cache" command on the toolbar to create a cache for the current view, or disable the cache.
(we can also use the "ESC" key to cancel the cache)
2. Use the "auto-Cache" command to automatically create and maintain the map cache.
3. Run the "show map cache" command to flash the map and identify whether the map is cached.
