    tf.raw_ops.LegacyParallelInterleaveDatasetV2(
        input_dataset,
        other_arguments,
        cycle_length,
        block_length,
        buffer_output_elements,
        prefetch_input_elements,
        f,
        output_types,
        output_shapes,
        deterministic='default',
        metadata='',
        name=None
    )

The resulting dataset is similar to the `InterleaveDataset`, with the exception
that if retrieving the next value from a dataset would cause the requester to
block, it will skip that input dataset. This dataset is especially useful
when loading data from a variable-latency datastores (e.g. HDFS, GCS), as it
allows the training step to proceed so long as some data is available.

!! WARNING !! This dataset is not deterministic!

| ## Args ||
|---|---|
| `input_dataset` | A `Tensor` of type `variant`. |
| `other_arguments` | A list of `Tensor` objects. |
| `cycle_length` | A `Tensor` of type `int64`. |
| `block_length` | A `Tensor` of type `int64`. |
| `buffer_output_elements` | A `Tensor` of type `int64`. |
| `prefetch_input_elements` | A `Tensor` of type `int64`. |
| `f` | A function decorated with @Defun. A function mapping elements of `input_dataset`, concatenated with `other_arguments`, to a Dataset variant that contains elements matching `output_types` and `output_shapes`. |
| `output_types` | A list of `tf.DTypes` that has length `>= 1`. |
| `output_shapes` | A list of shapes (each a [`tf.TensorShape`](https://www.tensorflow.org/versions/r2.13/api_docs/python/tf/TensorShape) or list of `ints`) that has length `>= 1`. |
| `deterministic` | An optional `string`. Defaults to `"default"`. |
| `metadata` | An optional `string`. Defaults to `""`. |
| `name` | A name for the operation (optional). |
