Is it possible to store binary data in GEODE or Gemfire? In particular, I would like to store binary structures of sparse voxel octrees and retrieve them using a 3D coordinate.
If yes, is it possible to create a client in C++?
Without knowing much about voxel structures, I can't comment on the best way to do this. Geode/GemFire is designed to store binary data. With a C++ client, you should use Geode's PDX serialization. If it's a simple matter of retrieving a structure given a known coordinate, Geode should work well.
