109	TODO: keep two files, one for [operation, version, id] and the other for the actual
110	document data. That way we could throw away document log files more readily
111	while retaining the smaller operation log files longer (and we can retrieve
112	the stored fields from the latest documents from the index).
113
114	This would require keeping all source fields stored of course.
115
116	This would also allow to not log document data for requests with commit=true
117	in them (since we know that if the request succeeds, all docs will be committed)
