  • expr.sh is used to run the experiments. bash ./expr.sh <s3|redis> <setting_id> <ditto|nimble> (optional) <jct|cost> is used to run the experiments for S3 and Redis, respectively. setting_id can be set to 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, following the order from left to right of the x-axis of all subfigures in Figure 11 in the paper. ditto and nimble are used to indicate the scheduling algorithms. jct and cost are used to indicate the objective functions, which is read by Ditto.
