This stores the metadata information present in each snapshot record.

• string graph_hash = 1

  Stores the fingerprint of the graph that describes the dataset that is snapshotted.

• string run_id = 2

  Run ID that this snapshot corresponds to.

• int64 creation_timestamp = 3

  Time when we started creating this snapshot.

• int64 version = 4

  Version of the snapshot data file format.

• repeated DataType dtype = 5

  A list of tensor dtype corresponding to each element of the snapshot.

• bool finalized = 1000

Each SnapshotRecord represents one batch of pre-processed input data. A batch consists of a list of tensors that we encode as TensorProtos. This message doesn't store the structure of the batch.

• repeated TensorProto tensor = 1

Metadata for all the tensors in a Snapshot Record.

• repeated TensorMetadata tensor_metadata = 1

Metadata for a single tensor in the Snapshot Record.

Used in: SnapshotTensorMetadata

• optional TensorShapeProto tensor_shape = 2

• int64 tensor_size_bytes = 3

  Number of uncompressed bytes used to store the tensor representation.
