/// Generates a new random correlation ID for use in read requests.

/// You must use the same correlation ID for all read segment column and

/// Using the same correlation ID when reading different segments or the same

/// in errors or inconsistent data.
/// Therefore, calling this function once each time you need to read a segment
/// is the best option.
