    • The embodiments of the present circuit and method disclose a bridge rectifier and a driving circuit. The bridge rectifier having a first input, a second input, a first output, and a second output may comprise two high side diodes and two low side switches. The driving circuit may be coupled to the first input of the bridge rectifier and the second input of the bridge rectifier, and the driving circuit may be configured to provide a first driving signal and a second driving signal. The first driving signal may be coupled to a first low side switch and the second driving signal may be coupled to a second low side switch. The first driving signal may be limited to less than a first predetermined driving voltage and the second driving signal may be limited to less than a second predetermined driving voltage.

    • Aspects of the subject matter described herein relate to data change ordering in multi-log based replication. In aspects, local seeds are maintained for subtransactions involved in a transaction, where each subtransaction may occur on a different node that hosts one or more database fragments involved in the transaction. When a subtransaction communicates with another subtransaction in a transaction, the subtransaction sends its local seed to the other subtransaction. The receiving subtransaction compares its local seed with the received seed and updates its local seed if the received seed is logically after its local seed. A subtransaction uses a local seed to generate sequence identifiers for changes made by the subtransaction. These identifiers allow data changes of a transaction that are made on multiple nodes to be partially ordered relative to other changes made during the transaction.
    • 本文描述的主题的方面涉及基于多日志的复制中的数据改变排序。 在方面中,维护涉及事务的子事务的局部种子,其中每个子事务可以在承载事务涉及的一个或多个数据库片段的不同节点上发生。 当子事务与事务中的另一个子事务通信时,子事务将其本地种子发送到另一个子事务。 接收的子事务将其本地种子与接收的种子进行比较,如果接收的种子在其本地种子之后是逻辑上的,则更新其本地种子。 子事务使用本地种子为子事务所做的更改生成序列标识符。 这些标识符允许在多个节点上进行的事务的数据更改相对于在事务期间进行的其他更改而被部分排序。

    • System and methods manage concurrent ETL processes accessing a database. Exemplary embodiments include a method for concurrency management for ETL processes in a database having database tables and communicatively coupled to a computer, the method including establishing a session lock for the database, determining that a current ETL process is accessing the database at a current time, associating a current expiration time with the session lock, the expiration time being stored in a lock table in the database, sending the session lock to the current ETL process and performing ETL-level locking for the current ETL process.
    • 系统和方法管理访问数据库的并发ETL进程。 示例性实施例包括用于具有数据库表并且通信地耦合到计算机的数据库中的ETL进程的并发管理的方法,所述方法包括为数据库建立会话锁定,确定当前ETL进程正在当前时间访问数据库, 将当前到期时间与会话锁相关联,到期时间存储在数据库中的锁定表中,将会话锁定发送到当前ETL进程,并为当前ETL进程执行ETL级别锁定。

    • A message converting method is disclosed, including: recognizing a type of a received message, sending the message to a message parsing module matching the type of the message; acquiring recipient information and the content of the message carried in the message; selecting an destination communication manner supporting the content of the message, and acquiring new recipient information corresponding to the recipient information and the destination communication manner; encapsulating the sender information, the new recipient information and corresponding content of the message supported by the destination communication manner, and sending a new message generated through the encapsulation to an address designated by the new recipient information. A message converting device is also disclosed. A communication manner suitable for content of message may be selected for sending the message, thus bringing convenience to users, and lowering requirements on terminals.
