Figure 7-3. A square can be recursively divided into quarters and labeled in such a way that the
roughly round regions will overlap squares that are nearly contiguous. This ordering can make re-
trieving the contents associated with each square fast in a database like HBase or MapR-DB be-
cause it results in more streaming I/O. This labeling is recursively defined and is closely related to
the Hilbert curve.
Whether or not this is an important optimization will depend on how large your geo-index of
squares is. Note that Hilbert labeling of squares does not change how the time series them-
