H5P_SET_ISTORE_K sets the size of the parameter used to control the B-trees for indexing chunked datasets. This function is valid only for file creation property lists.
ik is one half the rank of a tree that stores chunked raw data. On average, such a tree will be 75% full, or have an average rank of 1.5 times the value of
The HDF5 library uses
(ik*2) as the maximum # of entries before splitting a B-tree node. Since only 2 bytes are used in storing # of entries for a B-tree node in an HDF5 file,
(ik*2) cannot exceed
65536. The default value for
