+ * \page maybe_metadata_reads Functions with No Access Property List Parameter that May Generate Metadata Reads
+ *
+ * \ingroup GACPL
+ *
+ * Currently there are several operations in HDF5 that can issue metadata reads
+ * from the metadata cache, but that take no property list. It is therefore not
+ * possible to set a collective requirement individually for those operations. The
+ * only solution with the HDF5 1.10.0 release is to set the collective requirement
+ * globally on H5Fopen() or H5Fcreate() for all metadata operations to be
+ * collective.
+ *
+ * The following is a list of those functions in the HDF5 library. This list is
+ * integral to the discussion in the H5Pset_all_coll_metadata_ops() entry:
+ *
+ * <pre>
+ *
+ * H5Awrite()
+ * H5Aread()
+ * H5Arename()
+ * H5Aiterate2()
+ * H5Adelete()
+ * H5Aexists()
+ *
+ * H5Dget_space_status()
+ * H5Dget_storage_size()
+ * H5Dset_extent()
+ * H5Ddebug()
+ * H5Dclose()
+ * H5Dget_create_plist()
+ * H5Dget_space() (when dataset is a virtual dataset)
+ *
+ * H5Gget_create_plist()
+ * H5Gget_info()
+ * H5Gclose()
+ *
+ * H5Literate()
+ * H5Lvisit()
+ *
+ * H5Rcreate()
+ * H5Rdereference2() (when reference is an object reference)
+ * H5Rget_region()
+ * H5Rget_obj_type2()
+ * H5Rget_name()
+ *
+ * H5Ocopy()
+ * H5Oopen_by_addr()
+ * H5Oincr_refcount()
+ * H5Odecr_refcount()
+ * H5Oget_info()
+ * H5Oset_comment()
+ * H5Ovisit()
+ *
+ * H5Fis_hdf5()
+ * H5Fflush()
+ * H5Fclose()
+ * H5Fget_file_image()
+ * H5Freopen()
+ * H5Fget_freespace()
+ * H5Fget_info2()
+ * H5Fget_free_sections()
+ * H5Fmount()
+ * H5Funmount()
+ *
+ * H5Iget_name()
+ *
+ * H5Tget_create_plist()
+ * H5Tclose()
+ *
+ * H5Zunregister()
+ * </pre>
+ *
+ * In addition, \b most deprecated functions fall into this category.
+ *
+ * The HDF Group may address the above limitation in a future major release, but
+ * no decision has been made at this time. Such a change might, for example,
+ * include adding new versions of some or all the above functions with an extra
+ * property list parameter to allow an individual setting for the collective
+ * calling requirement.
