During this period, nothing big happened except we’re able to get merge a new Plasma subclass supposed to work with OpenPMD Datasets #500! It still isn’t very efficient to work with larger datasets and should rather be considered a prototype at the moment. It currently supports reading only mesh data from an HDF5. It also reads the complete record into memory, which is certain to cause problems with big datasets. In the real world, heavy datasets can go into dozens of GBs. In the future, we’re going to have to provide a way to read stuff directly from disk or provide someother way instead writing all of it to memory.
