    Args:
        first_snapshot_id: <p>The ID of the first snapshot to use for the comparison.</p> <important> <p>The <code>FirstSnapshotID</code> parameter must be specified with a <code>SecondSnapshotId</code> parameter; otherwise, an error occurs.</p> </important>
        second_snapshot_id: <p>The ID of the second snapshot to use for the comparison.</p> <important> <p>The <code>SecondSnapshotId</code> parameter must be specified with a <code>FirstSnapshotID</code> parameter; otherwise, an error occurs.</p> </important>
        next_token: <p>The token to request the next page of results.</p> <p>If you specify <b>NextToken</b>, then <b>StartingBlockIndex</b> is ignored.</p>
        max_results: <p>The maximum number of blocks to be returned by the request.</p> <p>Even if additional blocks can be retrieved from the snapshot, the request can return less blocks than <b>MaxResults</b> or an empty array of blocks.</p> <p>To retrieve the next set of blocks from the snapshot, make another request with the returned <b>NextToken</b> value. The value of <b>NextToken</b> is <code>null</code> when there are no more blocks to return.</p>
        starting_block_index: <p>The block index from which the comparison should start.</p> <p>The list in the response will start from this block index or the next valid block index in the snapshots.</p> <p>If you specify <b>NextToken</b>, then <b>StartingBlockIndex</b> is ignored.</p>
