Abstract:
A request from previous coordinator node to assume control of a two-phase commit distributed transaction is received. The previous coordinator node has sent a commit query to multiple participants of the two-phase commit distributed transaction. Each participant can respond with one of a commit message, an abort message, or a read-only message. A read-only message is received from all but one participant. A one-phase commit distributed transaction is initiated for the one participant that did not respond with a read-only message.
