   @vinothchandar 
   Hilbert curve has better data aggregation characteristics, while Z curve has worse data aggregation characteristics.
   
   The mapping process of Hilbert curve is complex, and the mapping process of Z curve is simple.
   
   High order Hilbert computation is very complex and time-consuming, and z-order is used more in spatio-temporal database.
   
   i will paste  perf test  later
