Reliability exercises often focus on what happens when a site or a link fails during a transaction. The 2PC Protocol Steps:
Maintaining data consistency across multiple independent sites requires specialized serialization protocols. Two-Phase Locking (2PL) vs. Distributed 2PL Reliability exercises often focus on what happens when
In distributed systems, deadlocks can occur across sites. Solutions often involve a "Global Wait-For Graph" (GWFG) or timestamp-based techniques like "Wait-Die" or "Wound-Wait" to prevent circular dependencies between remote transactions. Reliability and Replication Reliability exercises often focus on what happens when
Participants who voted "Commit" must wait in an uncertain state until the coordinator recovers. They cannot unilaterally abort because the coordinator might have sent a commit to another node before crashing. Reliability exercises often focus on what happens when
