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.
Cheers
