Which technique is used for error correction for every compressed block in cassandra?
Answers
The missing question options are
1. Parity bit
2. Hashing
3. CRC
4. ECC
The answer is 3. CRC.
CRC stands for cyclic redundancy check. It is a method of detecting accidental errors in digital raw data.
Cassandra is an opensource database, which is capable of handling a large amount of digital data.
The large amount of data handled result in a lot of errors.
Cassandra uses the cyclic redundancy check method in which a check value is attached to the data entered.
On retrieval of data the mismatched check value is checked for error and the needed action is taken.
Compressed sensing method is used of error correcting over the all compressed block in the Cassandra’s. it is used to forward error correction and build with the isometric property become more achieved by choosing each member of A to be simple and easy for the student.
Hope this answer is support student to get an ideas of it without meeting any trouble of it .
