 These experiments measured overall storage overhead and end-end query latency for synthetic dataset with data manipulation, i.e. INSERT/UPDATE/DELETE. Run `python run_benchmark_data_manipulation.py` to benchmark it. To benchmark with different dataset, you should modify the file correspondingly by following the instructions provided in the python file.
