Numerous applications such as wireless communication and telematics need to keep track of evolution of spatio-temporal data for a limited past. Limited retention may even be required by regulations. In general, each data entry can have its own user specified lifetime. It is desired that expired entries are automatically removed by the system through some garbage collection mechanism. This kind of limited retention can be achieved by using a sliding window semantics similar to that from stream… CONTINUE READING
