Julian Reschke commented on OAK-2191:
-------------------------------------
Looking at the code in DocumentMK, it seems that the PersistentCache is used
for the MongoBlobStore, but not the RDBBlobStore. Is this intentional???

> When using the DocumentNodeStore, data is read from a remote system (MongoDB
> or RDBMS), which is typically relatively slow. There is an in-memory cache,
> but this cache doesn't help much for startup.
> We should investigate whether a persistent cache would help.
