In one implementation, a data set including a plurality of data values having an order is stored at a memory having a plurality of memory locations. Each data value from the data set stored a current memory location of that data value from the plurality of memory locations. Each data value from the data set is periodically moved from the current memory location of that data value from the plurality of memory locations to a next memory location of that data value from the plurality of memory locations. The next memory location of each data value from the plurality of memory locations is the current memory location of that data value from the plurality of memory locations after the moving. The plurality of data values is then provided in the order to a client in response to a request for the data set.
