index_key
: Name of index feature. The underlying feature's type must be int64
and its length must always match that of the value_key
feature.value_key
: Name of value feature. The underlying feature's type must be dtype
and its length must always match that of the index_key
feature.dtype
: Data type of the value_key
feature.size
: A Python int to specify a dimension of the dense shape. Each value in the index_key
feature must be in [0, size)
.already_sorted
: A Python boolean to specify whether the values in index_key
are already sorted. If so skip sorting. False by default (optional).already_sorted
