@maysamyabandeh -- How would you like to initialize the txn_state_ here?

STARTED is fine. This is always initialized to STARTED in the PessimisticTransaction constructor:
56 void PessimisticTransaction::Initialize(const TransactionOptions& txn_options) {
57 txn_id_ = GenTxnID();
58
59 txn_state_ = STARTED;
