case class CachedDataSource(dataSource: PropertyGraphDataSource, storageLevel: StorageLevel) extends PropertyGraphDataSource with Product with Serializable

Wraps a PropertyGraphDataSource and introduces a caching mechanism. First time a graph is read, it is cached in Spark according to the given StorageLevel and put in the datasource internal cache. When a graph is removed from the data source, it is uncached in Spark and removed from the datasource internal cache.

dataSource

storageLevel
