Problems solved by technology

[0004] The existing distributed cache arrays have the following problems in data processing. The load capacity of the application server is limited. When faced with large data-intensive data update requests, the response is slow and multiple lock operations on data are prone to occur. Locks will cause subsequent requests to accumulate, and the processing capacity of the server itself is not fully utilized at this time

Embodiment Construction

[0019] In order to make the above-mentioned purpose, features and advantages of the present invention more obvious and understandable, a detailed description will be given below in conjunction with specific implementations of the distributed cache array and data query method of the present invention.

[0020] The capacity and storage capacity of existing centralized cache arrays are limited by hardware capacity and scalability, and capacity cannot be expanded on demand. Using multiple cache arrays for distributed partition storage (sub-storage instance storage) requires a specific hash function to locate data partitions before storing them. In practical applications, it is easy to cause load imbalance among different storage instances, and the storage of the entire cluster may fail due to storage overflow of one storage instance. And in the case of relying on a specific hash function for data partitioning, if the condition for data update is not the key value used by the hash ...

Abstract

The invention provides a distributed cache array and a data updating method thereof. The data updating method comprises that: the cache array receives a data updating request from the outside, selects a storage case with light load as an agent case, and executes an agent updating operation; and the agent updating operation comprises that: the agent case sends to-be-stored data to other storage cases for storing. By the method, the data updating efficiency can be improved, the data updating time can be shortened, and the load of a server can be reduced.

Description

technical field [0001] The invention relates to data processing technology, in particular to a distributed cache array and a data update method thereof. Background technique [0002] With the advancement of science and technology, the amount of data used to describe information is also increasing, and the scope of data is becoming wider and wider, and the relationship between data has become more complex. In order to improve the working efficiency of data processing, higher requirements are put forward for data processing technology. [0003] At present, the data processing technology mainly used is first to store data into a cache array, and then operate on the data in the cache array. A cache array can also be said to be a collection of data. With the increase of data volume, a single server can no longer meet the data processing business requests of high-concurrency cache arrays, so distributed cache arrays based on off-site storage have emerged. The architecture of th...
