Big data is typically characterized by the following "Vs":
- Volume: The vast amount of data.
- Velocity: The speed at which data is generated and processed.
- Variety: The different types of data.
- Veracity: The uncertainty or reliability of the data.
- Value: The usefulness or insights derived from the data.
However, consistency is not typically considered one of the defining characteristics of big data. While data consistency is important in database management, it is not a core feature of big data itself.
Thus, the correct answer is \( \boxed{\text{Consistency}} \).
