摘要： Disclosed are a data truncation method and apparatus. The method comprises: when a calculation task is received, detecting whether a global lock is present; if not, providing a global lock according to the calculation task, and performing data truncation according to the calculation task; and if so, determining, according to an attribute of the global lock, whether to execute the calculation task. In the method, a global lock is used to guarantee the accuracy of distributed calculation data truncation, and the generation of error data is reduced and controlled, such that the accuracy of data is guaranteed from the outset, thereby preventing loss resulting from disorder possibly caused by data truncation; and the consumption of a file system and a database is reduced, thereby improving the overall operation performance of the system.
