When I use minimal heap to merge sort, it performs much better when there are a number of sorted tvlist ( tvlist_sort_threshold = 100). However it performs worse when there is only one tvlist (tvlist_sort_threshold = 0).

Not sure if I should revert this change.

+# When the average point number of timeseries in memtable exceeds this, the memtable is flushed to disk. The default threshold is 100000.
