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.
What happens if one of the participants fails during the commit process?
If a participant fails during the commit, the protocol ensures that all other participants will either commit or abort the transaction to maintain consistency.
How does the coordinator handle failures in the two-phase commit?
The coordinator can detect failures and may retry the commit process or ask participants to report their status, ensuring a consistent outcome.
Are there any limitations to the two-phase commit protocol?
Yes, 2PC can lead to blocking if the coordinator fails, and it requires all participants to be available, which can be a limitation in some scenarios.
