const ( PriorityHigh = txnutil.PriorityHigh PriorityNormal = txnutil.PriorityNormal PriorityLow = txnutil.PriorityLow )
Priority value for transaction priority.
const MaxTxnTimeUse = transaction.MaxTxnTimeUse
MaxTxnTimeUse is the max time a Txn may use (in ms) from its begin to commit. We use it to abort the transaction to guarantee GC worker will not influence it.
