Apache Griffin

Apache Griffin is a Data Quality Service platform built on Apache Hadoop and Apache Spark. It provides a framework process for defining data quality model, executing data quality measurement, automating data profiling and validation, as well as a unified data quality visualization across multiple data systems. It tries to address the data quality challenges in big data and streaming context.

Measure Model

  1. Accuracy(准确性)- Does data reflect the real-world objects or a verifiable source
  2. Profiling(统计)- Apply statistical analysis and assessment of data values within a dataset for consistency, uniqueness and logic
  3. Completeness(完整性)- Is all necessary data present
  4. Timeliness(实时性)- Is the data available at the time needed
  5. Anomaly detection(异常检测)- Pre-built algorithm functions for the identification of items, events or observations which do not conform to an expected pattern or other items in a dataset
  6. Validity(有效性)- Are all data values within the data domains specified by the business
