Which of the following statements about columns in Apache Cassandra is TRUE?
Select one:
a. Related columns are stored in the same row
b. Columns have a name, a value, and a timestamp
c. Rows in a column family can contain different numbers of columns
d. All of the above statements about columns in Apache Cassandra are true
Homework Answers
Option D is the correct answer
- Related columns are stored in same row,
- columns are stored with the name, value, and timestamp.
- rows in a column family can have different number of columns, It is fair to have 100 columns for one row and 2 for the other, as it is stored as the hashmap.
Thus all the properties which are related to the Cassandra database. Thus option D is the correct answer.
Friend, That was
a nice question to answer
If you have any doubts in understanding do let me know in the
