Hi All,
I have written *.h5 file using C++ HDF5 library. After that, I want to perform some queries on *.h5 file which will give me particular row from a file. I have written a code which will traverse all rows and compare with each and every row and at the end, it gives me the result. But this approach is *sequential *search and it is generating *performance* issue. Here I am looking for random data fetching from *.h5. Is there any better technique? and How should I apply better technique? H5 File Format:- [image: Inline image 1] Here what I want is access second row directly without traversing? Just like HashMap, which does in 0(1) time Sample code is very helpful here. Regards, Shamkumar
