Question

Describe the role of a distributed transaction coordinator in ensuring the consistency of data in a distributed database. How does it handle failures and recovery?

Expert Solution

Step 1: The Role of a Distributed Transaction Coordinator:

In a distributed database environment, it is crucial to have a distributed transaction coordinator that ensures data consistency.

When dealing with distributed databases, where data is spread across locations or servers, keeping data consistency becomes complex.

The distributed transaction coordinator (DTC) is a middleware part that manages transactions involving databases or data sources.

Its vital role includes guaranteeing these distributed transactions' atomicity, consistency, isolation, and durability (ACID properties).
