Can you explain how the two-phase commit protocol works?
Sure! The two-phase commit (2PC) protocol is used in distributed systems to ensure all participants agree on a transaction before it's committed.
What are the two phases in the two-phase commit?
The two phases are the 'prepare' phase, where participants vote on the transaction, and the 'commit' phase, where the transaction is finalized.
How does it handle failures during the process?
If a failure occurs, the protocol ensures that all participants either commit or abort the transaction, maintaining consistency.
Are there any drawbacks to using two-phase commit?
Yes, it can lead to blocking if a participant fails during the process, and it may introduce latency due to the waiting time for votes.
