Enum Constant Details
ONE_PHASEpublic static final TransactionOptions.TransactionType ONE_PHASEThe 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_PHASEpublic static final TransactionOptions.TransactionType TWO_PHASEThe 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.
