Class AbstractJournal.BasicHA.VoteNoTask

java.lang.Object

com.bigdata.journal.AbstractJournal.BasicHA.VoteNoTask

All Implemented Interfaces:

Callable<Boolean>

Enclosing class:

AbstractJournal.BasicHA

protected class AbstractJournal.BasicHA.VoteNoTask
extends Object
implements Callable<Boolean>

Task votes NO (unconditional).

Note: If we were not joined at the start of the 2-phase commit, then we will not participate. This provides an atomic decision point with respect to when a service that is rebuilding or resynchronizing will participate in a 2-phase commit. By voting NO here, the commit2Phase() operation will be a NOP for THIS service.

Note: The vote of a service that was not joined with the met quorum at the time that we begin the 2-phase commit protocol is ignored.
