Variables

var CronForwardDuration time.Duration = time.Duration(0)

CronForwardDuration will be set in test. cron will fetch trans which expire in CronForwardDuration

var NowForwardDuration time.Duration = time.Duration(0)

NowForwardDuration will be set in test, trans may be timeout

var TransProcessedTestChan chan string = nil

TransProcessedTestChan only for test usage. when transaction processed once, write gid to this chan

var UpdateBranchAsyncInterval = 200 * time.Millisecond

UpdateBranchAsyncInterval interval to flush branch
