How does transaction management work in NoSQL databases?

In NoSQL databases, transaction management can vary significantly from traditional SQL databases. Most NoSQL systems prioritize scalability and performance over strict ACID compliance. Instead, they often implement eventual consistency, allowing for more flexible transaction models.

What are the main differences between ACID and BASE in this context?

ACID stands for Atomicity, Consistency, Isolation, Durability, which ensures reliable transactions. BASE, on the other hand, stands for Basically Available, Soft state, Eventually consistent, focusing on availability and partition tolerance, which is more common in NoSQL.

Can you give examples of NoSQL databases that handle transactions?

Sure! Some NoSQL databases that handle transactions include MongoDB, which supports multi-document ACID transactions, and Couchbase, which offers a form of distributed transactions.

What are the challenges of implementing transactions in NoSQL?

Challenges include managing consistency across distributed systems, handling partial failures, and ensuring data integrity without traditional locking mechanisms.
