Hi hackers,
The low-level implementation of 3D Z-curve index
(https://github.com/bmuratshin/zcurve/tree/master)
is getting close to GiST R-Tree performance at
significantly lesser number of pages read from disk.
See attached figures,
times2 - average request execution time VS average points number in result
reads2 - average shared reads number VS average points number in result
Feel free to connect with me if you have any questions.
