Question
What is the primary challenge associated with data consistency in NoSQL databases?a)Inability to handle high data volumesb)Lack of a well-defined schemac)Difficulty in querying datad)Lack of support for distributed transactions
Solution
The primary challenge associated with data consistency in NoSQL databases is d) Lack of support for distributed transactions.
NoSQL databases are designed to handle high data volumes, flexible schemas, and efficient querying of data. However, they often lack support for distributed transactions, which can lead to inconsistencies in data across different nodes in a distributed system. This is because NoSQL databases prioritize availability and partition tolerance over consistency, as per the CAP theorem.
In a distributed transaction, multiple related changes to data are made across different nodes. If one of these changes fails, the entire transaction should ideally be rolled back to maintain data consistency. However, many NoSQL databases do not support this feature, leading to potential inconsistencies.
