Even so, object databases have vertical scaling limits for very large
objects, for some value of "very". The RocksDB FAQ says that keys and
values should not be more than 8MB and 3GB respectively. Is 3GB very
large? That depends on your data. It might be sufficient for email
messages... until someone starts mailing "Linux ISOs", blows out the
database and crashes your mail system.
