| Abstract | To benchmark and rate a data store, one must repeat experiments that impose a different amount of load on the data store. Workloads that modify the benchmark database may require the same database to be loaded repeatedly. This may constitute a significant portion of the time to rate a data store. This paper presents several agile data loading techniques to expedite the rating process. These techniques include generating the disk image of the database once and re-using it, restoring the updated data items to their original value, maintaining in-memory state of the database across different experiments to avoid repeated loading of the database all together, and a hybrid of the third technique in combination with the other two. These techniques are general purpose and apply to a variety of cloud benchmarks. We investigate their implementation and evaluation in the context of one, the BG benchmark. Obtained results show a factor of two to twelve speedup in the rating process. As an example, when evaluating MongoDB with a million member BG database, we show these techniques expedite BG's rating from 4 months (123 days) of continuous running to less than 11 days for the first rating experiment. Subsequent ratings of MongoDB with different workloads using the same database is much faster, in the order of hours. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
