Thus, in this context, is would appear that the scale factor is primarily useful as an insertion performance tuning tool. The mutable buffer size, in Figure~\ref{fig:sample_mt}, also generally has no clear effect. This is expected, because the buffer -contains onyl a small number of records relative to the entire dataset, +contains only a small number of records relative to the entire dataset, and so has a fairly low probability of being selected for drawing a sample from. Even when it is selected, rejection sampling is very inexpensive. The one exception to this trend is when using tombstones, |
