Hi, I plan to store the following per-particle information in HDF5
(1) Particle ID (unique) (2) Position (x,y,z) (3) Velocity (i,j,k) (4) Density (5) Apparent magnitude What is the recommended way to lookup/query a particle information given it's unique ID ? I have read about FastQuery/FastBit but it seems optimise to query a set of information rather than individual ones ? Should I approach the problem differently and supply a set of unique IDs so that FastQuery/FastBit returns a set corresponding to their IDs. I envisage that I will be incrementally adding up to between 300 x 10^9 - 1 x 10^12 unique particle point and continue to use the same query method.
