Re: Rados Protocoll

Hi Noah

Thank you for your comments.
My companies policy states that all software needs to go through a 
security assessment to be allowed to use in production. As all our tools 
are focused on java, a native implementation would be far easier to 
handle than a java binding of librados (which uses jna, which is also 
quite large).
Also with a native java implementation there is no "technology-break" 
using three different software packages from three maintainers as 
compared to one native java implementation which only relies on the 
RADOS Protocol.

As for the documentation you referenced: I didn't find a documentation 
of the RADOS Protocol which could be used to base an implementation of 
librados upon. Does anything like this exist, or would I need to 
"translate" the c implementation?
