baymax's Issues

请问使用这个框架的时候,在使用Best Efforts 1PC pattern的时候怎么保证一致性?

public void commit() throws SQLException {
    checkClosed();
    if(isAutoCommit){
        return;
    }
    SQLException sqlException = null;
    boolean first = true;
    for(Connection conn : openedConnection.values()){
        try{
            conn.commit();
        }catch(SQLException e){
            if(sqlException == null){
                sqlException = e;
            }
            if(first){
                // 第一次Commit就抛异常了,直接break
                break;
            }
        }
        first = false;
    }

    if(sqlException != null){
        throw sqlException;
    }
}

在connection.commit 中, 如果中间某个connection commit失败,但是其他的connection提交成功,这种情况怎么去保证数据的一致性呢?
