In addition, if dynamic mapping is turned on you can indicate that the values retrieved from the spatial engine for a mapping should be kept in memory to avoid the cost of querying the spatial engine next time the mapping is required, this is done by setting the cache flag in the configuration. This can be useful if you want to avoid the longer startup time but the key/fid mappings are still fairly static (so it's safe to have them loaded once). This provides a middle ground, if suitable, between a static, loaded at startup, key/fid mapping, and a dynamic, performed each time, key/fid mapping.

Previously a single spatial mapper could be used with multiple spatial engines, by setting the spatial engine attribute for each mapping, but that is not longer possible. If you have multiple spatial engines you need to have multiple spatial mappers configured, one for each spatial engine. Setting the spatial engine at the mapping level is no longer supported, it must be set once at the top level for the spatial mapper. |
