Distributed Transactions

Distributed Transactions

Distributed transaction refers to a transaction in which multiple servers are involved. Multiple servers are called by a client in Simple Distributed Transaction whereas a server calls another server in Nested Transaction. The execution of a transaction at many sites, must either be committed at all sites or aborted at all sites. However, this should not be the case when a transaction is committed at one site and aborted at another site. Distributed site systems use distributed commitment rules to ensure atomicity across sites. Atomic commitment is a channel of need for cooperation across a variety of systems....

Properties of the Distributed Transactions

The distributed transactions must possess the following ACID properties, like any other transaction. In distributed systems, a transaction manager is used to coordinate the distinct operations and then commit/rollback the transaction as needed....

Atomic Commit

The atomic commit procedure should meet the following requirements:...

Distributed One-Phase Commit

A one-phase commitment protocol involves a coordinator who communicates with servers and performs each task regularly to inform them to perform or cancel actions i.e. transactions....

Distributed Two-Phase Commit

There are two phases for the commit procedure to work:...

Conclusion

In Conclusion, the Atomic Commit Protocol is essential to maintaining transaction dependability and consistency in distributed systems. Its main goal is to ensure that, even in the event of a failure, a transaction is either fully committed or fully aborted across all participating nodes....
