- on fourq.getData() calls
- check typename.objectpool for UUID
- if present
- return struct
- if not,
- make dbgateway call
- check if room in objectpool
- purge/update aobjects FIFO list as required
- update objectpool with object struct
- return struct
- update cache stats
- if present
- check typename.objectpool for UUID
- return object struct to content type call exactly as per original
Essentially update dbgateway calls for CRUD methods in fourq.cfc with calls to object broker. dbgateway would then be responsible for making calls on the Object broker. Update delete and setdata calls to purge objectpool as required.
