Review Comment:
I was thinking about something like this, and since we don't have dependency
on `data` here, we could do this in `PartitionStatsHandler`
````
public static Collection<PartitionStats> computeStats(Table table, Snapshot
snapshot) {
return computeStats(table, snapshot, true);
}
public static Collection<PartitionStats> computeStats(Table table, Snapshot
snapshot, boolean recompute) {
....
if (!recompute && latestStatsFile != null) {
load incremental
}
}
