Edge Case: What if the system went down ?

[GauravWalia19]

Then we have to re runs all the insertions again to this KD Tree

Below is the feature that I am suggesting we can add -
We can have mode that will save this in memory KD Tree to hard disk and after system is up we can rebuild the tree and we don't have to run the insertion again (basically is same like redis stores I guess in hard disk)

Indeed this is the request I have received many times. Thanks for creating an issue for this @GauravWalia19, we can track it easily now.

I'll prioritize this request soon. Thanks for the suggestion 🚀
