Jonathan Ellis commented on CASSANDRA-213:
------------------------------------------
> Why do you want to get rid of the bootstrap staging code?
Because it's a lot less IO (50% less reads, to be exact) to have anticompact
split the old file into new files, each of which are served live until
bootstrap is complete, at which point the sent file is removed, than to copy
the to-send files out to a staging dir, and later re-scan the original file for
cleanup & writing what is left.

> DatabaseDescriptor.getBootstrapFileLocation to the node that is joining the

> There are probably other bugs / omissions we will find as we flesh this out.
