No, the "it is a cache" bit is only partial information, referring to the fact 
that Akonadi server is not storing data in either database of its file cache 
location in a permanent fashion but data being forwarded to actual backends 
like servers or local file storage.

This is the "forget about other information" bit, e.g. Akonadi's purposes of 
providing uniform data access across data types, across applications, 
providing change notifications, arbiting resource access, etc.

It is a bit like discovering that the Linux kernel is filling free RAM with 
data and claiming it is storing data there instead of on disk and then, when 
somebody points out that file system buffers are only transient data 
locations, rip out all RAM and complain that application data is gone as well.

Just because memory is used for caching data also present somewhere else does 
not imply that its only use case is caching. The very same applies for Akonadi 
server.

Cheers,
Kevin
