Enum Class TransactionOptions.TransactionType

All Implemented Interfaces:
Serializable, Comparable<TransactionOptions.TransactionType>, Constable
Enclosing class:

public static enum TransactionOptions.TransactionType extends Enum<TransactionOptions.TransactionType>
The type of transaction. With the type you have influence on how much guarantee you get when a member crashes when a transaction is committing.
  • Enum Constant Details


      public static final TransactionOptions.TransactionType ONE_PHASE
      The one phase transaction executes a transaction using a single step at the end; committing the changes. There is no prepare of the transactions, so conflicts are not detected. If there is a conflict, then when the transaction commits the changes, some of the changes are written and others are not; leaving the system in a potentially permanent inconsistent state.

      public static final TransactionOptions.TransactionType TWO_PHASE
      The two phase commit is separated in 2 parts. First it tries to execute the prepare; if there are any conflicts, the prepare will fail. Once the prepare has succeeded, the commit (writing the changes) can be executed. Hazelcast also provides three phase transaction by automatically copying the backlog to another member so that in case of failure during a commit, another member can continue the commit from backup.
