Performance issue when indexing the data set of 'double' key type #3
Description
Hi Xinjing,
When I tested the DPTree using the data sets of the 'double' type, I observe that the performance of DPTree is extremely low and even has the segmentation fault. Probably it is because you assume that key-type is 'uint64_t' when writing the code.
The data sets I tested are longlat and longitudes. The method to read the keys from the file is here.
Could you take a look how to fix it?
Best,
Baotong
