tf.raw_ops.SnapshotDatasetV2(
    input_dataset,
    path,
    reader_func_other_args,
    shard_func_other_args,
    output_types,
    output_shapes,
    reader_func,
    shard_func,

    metadata='',
    name=None
)

This dataset attempts to determine whether a valid snapshot exists at thesnapshot_path, and reads from the snapshot in lieu of using input_dataset. If not, it will run the preprocessing pipeline as usual, and write out a snapshot of the data processed for future use.

Args
input_dataset	A Tensor of type variant. A variant tensor representing the input dataset.
path	A Tensor of type string. The path we should write snapshots to / read snapshots from.
reader_func_other_args	A list of Tensor objects.
shard_func_other_args	A list of Tensor objects.
output_types	A list of tf.DTypes that has length >= 1.
output_shapes	A list of shapes (each a tf.TensorShape or list of ints) that has length >= 1.
reader_func	A function decorated with @Defun. Optional. A function to control how to read data from snapshot shards.
shard_func	A function decorated with @Defun. Optional. A function to control how to shard data when writing a snapshot.
compression	An optional string. Defaults to "". The type of compression to be applied to the saved snapshot files.
reader_prefix	An optional string. Defaults to "".
writer_prefix	An optional string. Defaults to "".
hash_valid	An optional bool. Defaults to False.
hash	An optional int. Defaults to 0.
metadata	An optional string. Defaults to "".
name	A name for the operation (optional).

Returns
A Tensor of type variant.
