> In order to increase reproducibility of tests which measure things like the duration of operations or their latency, the idea is to record a log of the changes committed to the segment store, which could later be replayed. That replay is expected to produce the same results when run on the same machine under the same conditions. That way, different versions of the segment store can be compared more easily.

> where each line consists of a time stamp, the thread name, the operation (+ = added, - = removed, ^ = changed, ! = up to parent, n = node, p = property), the name (urlencoded except for : and / (for readability)), the type between angle brackets, and a value (urlencoded as well, and a comma-separated list between square brackets in case of multiple values). An 'n!' at the root node level ends a commit. Blob values are encoded as a simple string of bytes converted to hex.
