Analyzing and debugging processing pipelines in Big Data Analytics systems such as Apache Spark or Flink is a tedious task, which typically involves a lot of engineering effort. The task becomes even more complex when the pipelines process nested data. In this setting, detailed informarmation on how results of such pipelines were obtained could give developers valuable insights when analyzing and debugging their pipelines.
Motivated by this and other use cases, we research foundations, algorithms, and system architectures to offer provenance solutions tailored to nested data and the distributed and data-parallel processing leveraged by data analytics systems.
