Question: 1 / 400

What is the typical size of a TIMESTAMP data type in Cassandra?

32 bits

64 bits

The TIMESTAMP data type in Cassandra is used to represent a specific point in time with a precision that is suitable for most applications. It is typically stored as a 64-bit value, which allows it to represent dates and times with microsecond precision. This 64-bit representation generally consists of two parts: a 1-bit sign for the epoch value, a 32-bit integer for the number of seconds since a particular epoch (Unix epoch), and a 32-bit integer for the number of nanoseconds. While the majority of applications do not require higher than microsecond precision, the 64-bit size strikes a good balance between precision and storage efficiency, making it an ideal choice for timestamp data in a distributed database like Cassandra.
