The official specification can be found here.

Modules

• hca
  The directory layer offers subspace indirection, where logical application subspaces are mapped to short, auto-generated key prefixes. This prefix assignment is done by the High Contention Allocator, which allows many clients to allocate short directory prefixes efficiently.
