The features marked with * use new extensions to the HDF5 file format. o The Single-Writer / Multiple-Reader or SWMR feature enables users to read data while concurrently writing it. * o The virtual dataset (VDS) feature enables users to access data in a collection of HDF5 files as a single HDF5 dataset and to use the HDF5 APIs to work with that dataset. * NOTE: There is a known issue with the h5repack utility when using it to modify the layout of a VDS. We understand the issue and are working on a patch for it. o New indexing structures for chunked datasets were added to support SWMR and to optimize performance. * o Persistent free file space can now be managed and tracked for better performance. * o The HDF5 Collective Metadata I/O feature has been added to improve performance when reading and writing data collectively with Parallel HDF5. o The Java HDF5 JNI has been integrated into HDF5. o Changes were made in how autotools handles large file support (LFS). o New options for the storage and filtering of partial edge chunks have been added for performance tuning.* Files created with the new extensions will not be readable by applications based on the HDF5-1.8 library.
