Design a logging, timeout, and restart procedure for the linear commit protocol. Do not assume the existence of a separate coordinator module. Assume that all communication between cohorts is carried on along the chain.

What will be an ideal response?

The rightmost cohort keeps a log in which it stores commit records for distributed transactions. Each cohort forces a prepare record prior to sending a ready message to its neighbor. On recovery, a cohort in its uncertain period sends a query message down the chain. The coordinator uses the presumed abort property in replying to the query.
