grumpy (development version)

Significant new features

  • read_npy() gains a new lazy argument. When lazy = TRUE, raw bytes are read lazily using ALTREP and mmap against the .npy file on disk, resulting in much better speed & memory performance. This is following a feature request from @btraven00 in #11.
  • read_npz() gains a new arrays argument to allow reading only a subset of the arrays in the npz container.

Minor improvements

  • Elements of structured datatypes are now named if names were provided during the dataset creation.
  • read_npz() now adds names to the list it returns. The names are the names of the bundled .npy files without the file extension.
