Problems solved by technology

[0002] In the era of big data, the speed of data processing in production is becoming more and more stringent. In addition to the improvement of the engine, caching technology is undoubtedly being valued by more and more people. Interaction speed, but the cache cannot be used as a persistent disk after all, so there is a process of data expiration in the cache
Existing data expiration and cleanup strategies linearly invalidate data, which can easily cause cache avalanche

Embodiment Construction

[0045] In order to make the object, technical solution and advantages of the present invention clearer, the embodiments of the present invention will be further described in detail below in conjunction with specific embodiments and with reference to the accompanying drawings.

[0046] It should be noted that all expressions using "first" and "second" in the embodiments of the present invention are to distinguish two entities with the same name but different parameters or parameters that are not the same, see "first" and "second" It is only for the convenience of expression, and should not be construed as a limitation on the embodiments of the present invention, which will not be described one by one in the subsequent embodiments.

[0047] In the embodiment of the present invention, when the data needs to be cached, the data is cached through the cache space, and each batch (for example, according to the time range, such as data within 5s) is sent to the cache space as a unit, ...

Abstract

The invention discloses a method for diluting a cache space. The method comprises: in response to triggering, diluting the cache space, and performing data deletion on a queue with the maximum lengthin the cache space at a preset initial speed; in response to the fact that the length of the queue with the largest length for data deletion is equal to the lengths of the queues in the cache space, triggering the queues to perform data deletion; calculating an apportioning speed by utilizing the number of queues deleted by all triggering data and a preset initial speed; performing data deletion on each queue triggering data deletion at a uniform spreading speed; in response to the fact that the lengths of all the queues for data deletion are equal to the lengths of the other queues in the cache space, triggering the other queues to perform data deletion, and returning to the step of calculating the allocation speed; and stopping diluting the cache space in response to triggering, and suspending the data deleting process. The invention further discloses computer equipment and a medium.

Description

technical field [0001] The present invention relates to the cache field, in particular to a method, device and storage medium for diluting cache space. Background technique [0002] In the era of big data, the speed of data processing in production is becoming more and more stringent. In addition to the improvement of the engine, caching technology has undoubtedly been valued by more and more people. The development of caching technology has greatly improved the data processing speed. Interaction speed, but the cache cannot be used as a persistent disk after all, so there is a process of data expiration in the cache. Existing data expiration and cleaning strategies all invalidate data linearly, which can easily cause cache avalanche phenomenon. Contents of the invention [0003] In view of this, in order to overcome at least one aspect of the above problems, an embodiment of the present invention proposes a method for diluting cache space, including the following steps: ...
