Persist Clause Samples

Persist. Persistence of datasets happens throughout the whole data management process. When a new dataset comes into the SlideWiki platform, the first data persistence is to backup this dataset and the ingestion result of this dataset. Later data persistence is largely determined by the data analysis process. Two strategies used in data persistence are (a) keeping local copy – copy the dataset from DSPO to the SlideWiki platform; (b) caching, to enhance data locality to increase the efficiency of data management.
