Understand data types for generating unique identifiers in Cassandra.
- [Instructor] Cassandra provides a tuples data type…to create structured collections.…Tuples are ordered lists of attributes.…They have a fixed structure.…This is different from lists and sets,…which can have varying lengths.…Also, the attributes in tuples can be of different types.…For example, if we need to track the location of sensors,…we might want to specify the latitude,…longitude, and altitude of the sensor.…We can do this using a tuple,…such as the one used in this create table statement.…
This statement creates a table with a unique ID,…a sensor name, and a location defined…as a data structure with three attributes.…The order of the attributes is important.…The latitude is the first element of the list.…Longitude is the second and altitude is the third.…We use the insert statement to insert tuple values.…So for example, this creates a row…with the last column being the tuple value.…Tuples are used when you want to logically group…several attributes and you will not need…to add any new attributes in the future.…
