org.hornetq.core.persistence.impl.journal.OperationContextImpl
Each instance of OperationContextImpl is associated with an executor (usually an ordered Executor). Tasks are hold until the operations are complete and executed in the natural order as soon as the operations are returned from replication and storage. If there are no pending IO operations, the tasks are just executed at the callers thread without any context switch. So, if you are doing operations that are not dependent on IO (e.g NonPersistentMessages) you wouldn't have any context switch. @author Clebert Suconic
