Currently, it is not possible to save the state of an analysis to a file, and to restore it afterwards. This hampers (performance) testing and debugging, especially for incremental analyses: to test an incremental update, a full initial analysis must be run beforehand (to deliver the analysis state that is to be updated), and a full reanalysis must be run afterwards (to verify the correctness of the analysis). Therefore, adding persistent storage of analyses will lead to a major improvement in the debug and test cycle, and can be useful for benchmarking as well.

Analyses can possibly be stored using the .json format.
