Spark doesn't have persistent storage (besides persisting in-memory), but a database may be accessed with native drivers or APIs.
Data in Spark is handled as parallelizable RDDs, which may also be persisted in-memory.
Everyone has a secret place that persists in memory.
The last survivor of the Triangle Shirtwaist fire, Rose Freedman, died on Feb. 15, but the blaze on March 25 , 1911 which killed 146 of her co-workers, persists in memory.

Despite antiretroviral therapy, HIV-1 persists in memory CD4+ T cells, creating a barrier to cure.
Measurements transmitted to PLC's are persisted in memory at set intervals (e.g. every 15 min) as tuples of timestamp/value.
Current memory analyzers and memory leak detectors can only figure out what objects are (unnecessarily) persisted in memory but cannot figure out where the objects come from and why the objects become so large.
Thus our findings suggest that graph distortions mislead users into incorrect conclusions about the underlying data and that these interpretation errors persist in memory and affect judgments and investment decisions.
