> We need to introduce a new transaction attribute: transaction priority. This
> addition is necessary to resolve potential conflicts between user
> transactions and internal Ignite services transactions. Transactions from
> services should be assigned a LOW priority. In the event of a conflict, the
> DeadlockPreventionPolicy will assess the priorities of the involved
> transactions. If the priorities are the same, the policy will then compare
> timestamps; otherwise, the transaction with the lower priority will be rolled
> back.
