Class TransactionState

  • public class TransactionState
    extends java.lang.Object

    This class manages the transaction state associated with every client session. The transaction state for the current session can be retrieved like this:

        TransactionState txnState = SessionState.get().getTransactionState()

    The transaction state should generally not be managed directly! Rather, the operations provided by the TransactionManager should be used.

    • Field Detail

      • transactionID

        private int transactionID
      • userStartedTxn

        private boolean userStartedTxn
      • performedWrites

        private boolean performedWrites
      • loggedTxnStart

        private boolean loggedTxnStart
        This value indicates whether the current transaction has been logged to the write-ahead log yet. We don't write the "Ti: start" record until the transaction performs its first write operation.
