Hi all,
I need to store around 50M objects in a spatial index (I need only support
for bulk insert and concurrent intersection() operations). I need then to
semi-randomly access the objects (that is, I probably will have 300
requests within one location, then another 300 in another random location,
etc.)
STRTree is great and fast, however I need around 50GB of RAM for fitting
the tree which is unfortunately too expensive for me to maintain in long
term.
I need a solution that can run on 1Gb of RAM and SSD disks (it's a
digitalocean cloud instance)
I have also tried using Lucene for storing spatial index, which is also
feasible but around 10 times slower even on SSD disks.
I was wondering if you know of any other minimal java libraries that can do
what I am looking for yet they are still relatively fast.
Thanks,
D.
