ONE_PHASE
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.
-
TWO_PHASE
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. For more information see theTransactionOptions.setDurability(int)

values
public static TransactionOptions.TransactionType[] values()
Returns an array containing the constants of this enum type, in the order they are declared. This method may be used to iterate over the constants as follows:for (TransactionOptions.TransactionType c : TransactionOptions.TransactionType.values()) System.out.println(c);
- Returns:
- an array containing the constants of this enum type, in the order they are declared
-
valueOf
public static TransactionOptions.TransactionType valueOf(java.lang.String name)
Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)- Parameters:
name
- the name of the enum constant to be returned.- Returns:
- the enum constant with the specified name
- Throws:
java.lang.IllegalArgumentException
- if this enum type has no constant with the specified namejava.lang.NullPointerException
- if the argument is null
