implements Serializable
    JDBC exactly once sink options.

    maxCommitAttempts - maximum number of commit attempts to make per transaction; must be > 0; state size is proportional to the product of max number of in-flight snapshots and this number.

    allowOutOfOrderCommits - If true, all prepared transactions will be attempted to commit regardless of any transient failures during this operation. This may lead to inconsistency. Default: false.

    recoveredAndRollback - whether to rollback prepared transactions known to XA RM on startup (after committing known transactions, i.e. restored from state).

    NOTE that setting this parameter to true may:

    1. interfere with other subtasks or applications (one subtask rolling back transactions prepared by the other one (and known to it))
    2. block when using with some non-MVCC databases, if there are ended-not-prepared transactions
