What is Distributed Transaction Coordinator (DTC)?
Distributed Transaction Coordinator (DTC) is a transaction management system that ensures the correctness of a distributed transaction applied consistently across various databases, systems, and architectures. DTC acts as the mediator of distributed transactions and coordinates the transaction between different databases.
How Distributed Transaction Coordinators Work?
Distributed Transaction Coordinator utilizes a two-phase commit protocol that ensures that the distributed transactions are applied consistently across all involved nodes. The DTC server acts as the transaction manager and coordinates the transaction between various databases.
The two-phase commit protocol used in DTC works as follows:
- The first phase is the preparation phase, where each node prepares to commit the transaction and signals the transaction coordinator.
- The second phase is the commit phase, where the transaction coordinator utilizes the prepared nodes to commit the transaction and the nodes either commit or abort the transaction.
Why is Distributed Transaction Coordinator Important?
Distributed Transaction Coordinator is important because it provides a seamless way to manage transactions across various databases, systems, and architectures. It eliminates the need for manual intervention and ensures the consistency, durability, and isolation of transactions across nodes. This enhances the reliability and scalability of applications, especially in distributed environments.
The Most Important Distributed Transaction Coordinator Use Cases
Distributed Transaction Coordinator can be used in various use cases, including:
- High-volume transactional systems that require ACID (Atomicity, Consistency, Isolation, Durability) compliance.
- Distributed systems that require transactional consistency across multiple nodes.
- Applications that require distributed transactions across multiple architectures and platforms.
Other Technologies or Terms Closely Related to Distributed Transaction Coordinator
Other technologies closely related to Distributed Transaction Coordinators include:
- Transaction processing systems (TPS)
- Transaction Managers (TM)
- Database management systems (DBMS)
