Which of the following data lakehouse features results in improved data quality over a traditional data lake?
A data lakehouse supports ACID-compliant transactions. ACID stands for Atomicity, Consistency, Isolation, and Durability, which are crucial properties for maintaining data integrity and consistency. These properties ensure that data operations are processed reliably and completely, even in the face of concurrent transactions or failures. This level of transactional reliability and consistency helps to improve data quality significantly over a traditional data lake, which often lacks such guarantees.
Option B - ACID Properties Source: https://www.databricks.com/blog/2021/08/30/frequently-asked-questions-about-the-data-lakehouse.html#five -> "Lakehouse tackles the fundamental issues that make data swamps out of data lakes. It adds ACID transactions to ensure consistency as multiple parties concurrently read or write data."
B. A data lakehouse supports ACID-compliant transactions. One of the key features of a data lakehouse that results in improved data quality over a traditional data lake is its support for ACID (Atomicity, Consistency, Isolation, Durability) transactions. ACID transactions provide data integrity and consistency guarantees, ensuring that operations on the data are reliable and that data is not left in an inconsistent state due to failures or concurrent access. In a traditional data lake, such transactional guarantees are often lacking, making it challenging to maintain data quality, especially in scenarios involving multiple data writes, updates, or complex transformations. A data lakehouse, by offering ACID compliance, helps maintain data quality by providing strong consistency and reliability, which is crucial for data pipelines and analytics.
B. A data lakehouse supports ACID-compliant transactions. ACID (Atomicity, Consistency, Isolation, Durability) compliance ensures that transactions are processed reliably and consistently, which is crucial for maintaining data integrity and quality. It helps in preventing data inconsistencies or errors that might occur during concurrent transactions or data operations. By supporting ACID-compliant transactions, a data lakehouse can enhance data quality by providing mechanisms to ensure the reliability and consistency of data operations, which is a notable improvement over traditional data lakes that might lack such transactional capabilities.
b is correct
B is correct answer. Only B deals with data quality i.e. ACID transactions make sure all the transactions are complete, isolated, consistent and durable.
ACID is the correct ans.
B is correct
Acid Transaction is the correct answer
Correct : B
A is the correct answer. Allowing SQL query to examine data does not improve the quality of the data. For example, if the person writes the wrong query they will get a wrong answer. So how does that improve the quality of the data?
point of correction: B is the correct answer, not A as posted in my previous comment
Correct andwer is B
B is correct
b is correct as acid transactions are related to data quality
B is Correct
The answer is B!
answer is B
