Caterva is a C library for handling multi-dimensional, compressed datasets in an easy and convenient manner. It implements a thin metalayer on top of C-Blosc2 for specifying not only the dimensionality of a dataset, but also the dimensionality of the chunks inside the dataset. In addition, Caterva adds machinery for retrieving arbitrary multi-dimensional slices (aka hyper-slices) out of the multi-dimensional containers in the most efficient way. Hence, Caterva brings the convenience of multi-dimensional and compressed containers to your application very easily.
