> h3. Motivation
> Read-only transactions start a scan operation and save transaction cursors on the replica side. The cursors stay on the server until they are closed. Read-only transactions finish locally and do not notify all replicas of the transaction.
> h3. Definition of done
> # Enlist node to RO transaction.
> # Prohibit adding operations to the read-only transaction after the transaction is finished.
> # Send the finish transaction request to all enlisted nodes to close cursors.
