Suppose that a transaction uses TRPC to update some data from a database at a remote site and that the call successfully returns. Before the transaction completes, the remote site crashes. Describe informally what should happen when the transaction requests to commit.
What will be an ideal response?
The TRPC has notified the coordinator that the remote site is a participant in the transaction. Therefore when the coordinator performs the two-phase commit protocol, it will attempt to contact that site. When it finds that the site has crashed, it will
abort the transaction.
