Bypassing default HDF5 behavior in order to optimize for specific use cases (H5DO)
- H5DO_APPEND — Appends data to a dataset along a specified dimension
- H5DO_READ_CHUNK — Reads a raw data chunk directly from a dataset in a file into a buffer (DEPRECATED)
- H5DO_WRITE_CHUNK — Writes a raw data chunk from a buffer directly to a dataset in a file (DEPRECATED)
HDF5 functions described is this section are implemented in the HDF5 High-level library as optimized functions. These functions generally require careful setup and testing as they enable an application to bypass portions of the HDF5 library’s I/O pipeline for performance purposes.
These functions are distributed in the standard HDF5 distribution and are available any time the HDF5 High-level library is available.
