H5Pset_link_phase_change
sets the
maximum number of entries for a compact group and the
minimum number of links to allow before converting a dense
group to back to the compact format.
max_compact
is the maximum number of links
to store as header messages in the group header as before
converting the group to the dense format.
Groups that are in compact format and in which the exceed this
number of links rises above this threshold
are automatically converted to dense format.
min_dense
is the minimum number of links to
store in the dense format.
Groups which are in dense format and in which the
number of links falls below this theshold
are automatically converted to compact format.
See “Group implementations in HDF5” in the H5G API introduction for a discussion of the available types of HDF5 group structures.
