> For larger data sets it's sometimes not needed to fit the entire index in memory ( there can be cold spots in the data, too much data in index, etc). However it's almost always needed to cache the root index. It's always the hottest blocks of the entire region.
> We should allow the root index block to be cached in memory on write. We should also do that by default.
