The objective of the WBDB workshops is to make progress towards development of industry standard application-level benchmarks for evaluating hardware and software systems for big data applications.
To make progress towards a big data benchmarking standard, the workshop will explore a range of issues including:
Data features: New feature sets of data including, high-dimensional data, sparse data, event-based data, and enormous data sizes.
System characteristics: System-level issues including, large-scale and evolving system configurations, shifting loads, and heterogeneous technologies for big data and cloud platforms.
Implementation options: Different implementation options such as SQL, NoSQL, Hadoop software ecosystem, and different implementations of HDFS.
Workload: Representative big data business problems and corresponding benchmark implementations. Specification of benchmark applications that represent the different modalities of big data, including graphs, streams, scientific data, and document collections.
Hardware options: Evaluation of new options in hardware including different types of HDD, SSD, and main memory, and large-memory systems, and new platform options that include dedicated commodity clusters and cloud platforms.
Synthetic data generation: Models and procedures for generating large-scale synthetic data with requisite properties.
Benchmark execution rules: E.g. data scale factors, benchmark versioning to account for rapidly evolving workloads and system configurations, benchmark metrics.
Metrics for efficiency: Measuring the efficiency of the solution, e.g. based on costs of acquisition, ownership, energy and/or other factors, while encouraging innovation and avoiding benchmark escalations that favor large inefficient configuration over small efficient configurations.
Evaluation frameworks: Tool chains, suites and frameworks for evaluating big data systems.
Early implementations: Of the Deep Analytics Pipeline or BigBench and lessons learned in benchmarking big data applications.
Enhancements: Proposals to augment these benchmarks, e.g. by adding more data genres (e.g. graphs), or incorporating a range of machine learning and other algorithms, will be entertained and are encouraged.
