That's an awfully large reset button you want to press, presumably the
benefits will justify the enormity of effort? What are we talking
here, 10x
Let's ask what we'll lose here.
4 years of work, tons of debugging, loads of instrumentation, for what
gain? Almost nil.

Roman,
I would start with figuring out exactly how much performance you’re

I'm not talking to throw away currently working code. Just port it to
C/C++, and have option to run Java based or "native" binary.

There is a _lot_ of room for performance improvements, both in terms of design
decisions but even more so in terms of implementation specifics on there.
I don’t think it makes sense (any kind of sense) to rewrite to C or any other
language, given the amount of work and(perhaps most importantly)

But as Brandon says, you would be throwing away so much work, would it be worth
it

You seem to think something like this is akin to a weekend project. I
would recommend you actually read some of the Cassandra source code and
better understand how it is architected.
