Data update method, device, data calling side and data update system

Abstract

The invention discloses a data update method, a device, a data calling side and a data update system. The method is applicable to a ZooKeeper colony and comprises the steps that whether data under each path nose in the colony is updated is monitored; and when the data under a path node is updated, an update notification is sent to the data calling side corresponding to the path node, so the data calling side can acquire latest data from the path node. Through application of the invention, a function of dynamically obtaining the latest data can be achieved.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a data updating method, device, data calling terminal and data updating system. Background technique [0002] In many systems now, information such as algorithm strategies of various applications can be placed in the memory, which is placed in the memory when the system is first started. In practical applications, developers or administrators of these applications often maintain and update their algorithm strategies, and at this time, the data caller needs to obtain updated data. In the existing technology, data is refreshed through certain trigger methods, such as timing tasks or manual triggering of data callers. However, when using these trigger methods to obtain updated data, it is necessary to initiate an update with the program developer or administrator. There is a certain time interval in the time, and the latest data information cannot be reflected in real time. ...

Problems solved by technology

In the existing technology, data is refreshed through certain trigger methods, such as timing tasks or manual triggering of data callers, etc. However, when using these trigger methods to obtain updated data, it is necessary to initiate an update with the program developer or administrator. There is a certain time interval in the time, and the latest data information cannot be reflected in real time. Therefore, it is necessary to provide a data update method, device, data calling terminal and data update system to achieve real-time acquisition of updated data.
