The data, ordered in a Dictionary by the hash (TimeAgent.guid + dataId) to optimize the performances. Then each entry contains the ordered list of data for each tick. Data will be stored this way (pseudo-code) : Dictionary [hashForTickDeltaTimes] = [ {Value=0, DeltaTime=0, origin=Record, Type=float}, {Value=0.005, DeltaTime=0.005, origin=Record, Type=float}, {Value=0.005, DeltaTime=0.005, origin=Record, Type=float} ] [hashForComponent1Position] = [ {Value={1,0,1}, DeltaTime=0, origin=Record, Type=Vector3}, {Value=1,1,1, DeltaTime=0.005, origin=Record, Type=Vector3}, {Value=1,2,1, DeltaTime=0.005, origin=Record, Type=Vector3} ] [hashForComponent2Position] = [...]
