If you generate ids like: <fixed width timestamp><random data> Your ids are guaranteed to be sorted chronologically until you start generating them at the same time. So as a hack to work around that they generate: <fixed width timestamp><fuzzed random data> Where the fuzz to the random data ensures that it's sorted chronologically.
