From this, you can calculate the number of sorts per transaction and the percentage of sorts that overflowed the memory that was available to them.
根据该输出,可以计算每个事务的排序数目,并可以计算溢出了可用于排序的内存的那部分排序的百分比。
They run in a single transaction and their state is only hold in memory and not persisted to the process server database.
它们在单个事务中运行,其状态仅保存在内存中,而不能持久性地保存到流程的服务器数据库中。
Note that even in the case of a rollback, the callback function must do some cleanup, removing all the records that were part of the transaction from the named memory.
注意,即便是回滚情况,回调函数也必须执行一些清理:从已命名内存删除作为事务一部分的所有记录。
