It should be understood that the number of terminal devices, networks, and servers in fig. 1 is merely illustrative. There may be any number of terminal devices, networks, and servers, as desired for implementation.
With continued reference to FIG. 2, a flow 200 of one embodiment of an information storage method according to the present application is shown. The information storage method comprises the following steps:
In this embodiment, an electronic device (for example, a server shown in fig. 1) on which the information storage method operates may receive an information storage request from another electronic device through a wired connection manner or a wireless connection manner. Wherein the information storage request includes key-value pairs (key and value), an expiration time, and object information of the specified object. The key-value pairs, expiration times, and object information, which are typically included in an information storage request, are content associated with the same object. Here, the information storage request may include one piece of information, which is a group of related key value pairs, expiration time, and object information, or may include multiple pieces of information.
The information storage request is a request sent to the electronic equipment and used for the electronic equipment to perform information storage operation. Specifically, the cache memory may be stored in a local cache memory, or may be stored in a cache memory of other electronic devices. The expiration time herein refers to the expiration time of the key-value pair in the information storage request. The object is an object obtained by instantiating a class in the object-oriented programming. For example, the item model may be abstracted into a class, and a certain item model numbered 1 is an object, and a certain item model numbered 2 is also an object. The object information is information related to an object, and object information of different objects is different. The designated object may be an artificially defined object or an object that is machine-generated or set.
In some optional implementation manners of this embodiment, the object information includes an object identifier.
In this embodiment, the object identifier is an identifier for distinguishing an object. The object identifier may be composed of a class name and an object number to which the object belongs.
In this embodiment, the key value pair is the content to be stored by the electronic device. The electronic equipment stores the key value pair in the information storage request into the cache region, and sets the expiration time value of the key value pair stored in the cache region. The expiration time value is a value of an expiration time set in the cache. In particular, the value of the expiration time in the information storage request may be set to the expiration time value of the key-value pair in the cache. For example, the expiration time in the information storage request may be 2017/05/16, 01:02:30, which may be used as the expiration time value for the key-value pair in the cache.
The cache region may be a database with a caching function, such as a redis database.
In this embodiment, the electronic device classifies the key of the key-value pair and the expiration time into an information set, and then stores the information set in a buffer. The information set is a set for collecting information and is associated with the object information. The information set may be pre-established or newly created for the key and expiration time of the key-value pair currently stored. Specifically, if the information set associated with the object information is already established in the cache area before the information storage request is received this time, the key and the expiration time of the key-value pair may be stored in the pre-established information set. If the information set associated with the object information is not established before, an information set associated with the object information needs to be established.
The object information of each object has an associated information set, and the object information of different objects is associated with different information sets.
After the key and expiration time of the key-value pair are correspondingly included in the information set, the key and expiration time of the key-value pair having a corresponding relationship are included in the information set. The key-value pair in the cache region can be searched relatively quickly through the key-value pair.
With continued reference to fig. 3, fig. 3 is a schematic diagram of an application scenario of the information storage method according to the present embodiment. In the application scenario of fig. 3, the electronic device 302 receives an information storage request 303 from the other electronic device 301, wherein the information storage request 303 comprises key-value pairs, expiration times 2017/03/05, 03:02:00, and object information of specified objects. Then, the electronic device 302 stores the key-value pair into a buffer, and sets an expiration time value 304 of the key-value pair in the buffer according to the expiration time; finally, the electronic device classifies the key of the key-value pair and the expiration time into an information set 305 associated with the object information, and stores the information set in a buffer 306.
According to the method provided by the embodiment of the application, the keys and the expiration times of the key value pairs are correspondingly classified into the information set associated with the object information, so that the key value pairs in the information set associated with the object information can be conveniently and accurately determined and deleted, the information is prevented from being deleted more or omitted, the consistency of the data in the database and the cache region is ensured, and the expandability of the system is improved.
With further reference to FIG. 4, a flow 400 of yet another embodiment of an information storage method is shown. The process 400 of the information storage method includes the following steps:
In this embodiment, the server on which the information storage method operates may receive the information storage request from the other electronic device by a wired connection manner or a wireless connection manner. Wherein the information storage request includes a key-value pair (key and value), an expiration time, and object information. The key-value pairs, expiration times, and object information, which are typically included in an information storage request, are content associated with the same object. Here, the information storage request may include one piece of information, which is a group of related key value pairs, expiration time, and object information, or may include multiple pieces of information.
The information storage request is a request sent to the server to enable the server to perform information storage operation. Specifically, the cache memory may be stored in a local cache memory, or may be stored in a cache memory of other electronic devices. The expiration time herein refers to the expiration time of the key-value pair in the information storage request. An object is an object that results from instantiating a class in object-oriented programming. For example, the item model may be abstracted into a class, and a certain item model numbered 1 is an object, and a certain item model numbered 2 is also an object. The object information is information related to an object, and object information of different objects is different.
In this embodiment, the key value pair is the content to be stored by the server. And the server stores the key value pair in the storage request into the cache region and sets the value of the expiration time of the key value pair stored in the cache region. The expiration time value is a value of an expiration time set in the cache. In particular, the value of the expiration time in the information storage request may be set to the expiration time value of the key-value pair in the cache. For example, the expiration time in the information storage request may be 2017/05/16, 01:02:30, which may be used as the expiration time value for the key-value pair in the cache.
In this embodiment, the server concatenates the keys of the key-value pairs and the expiration times, and puts the keys of the concatenated key-value pairs and the expiration times into the information set. The set of information is, and is associated with, object information. The spliced key and the expiration time have direct correspondence. In particular, the concatenation may be performed using a separator "-", i.e. a separator is used to connect the key and the expiry time.
In this embodiment, after obtaining the information set including the key of the corresponding key-value pair and the expiration time, the server stores the obtained information set in the cache region, so as to modify or delete the key-value pair through the key of the key-value pair in the following process.
In response to receiving a delete request for the cache information of the specified object, an information set associated with the object information is determined, step 405.
In this embodiment, the server responds, after receiving a deletion request for the cache information of the specified object: an information set associated with the object information of the specified object is determined. The deletion request here is a request for information of a specified object. The cache information of the specified object is information about the specified object that has been stored in the cache area. For example, the information set may include information sets related to object information of the object, or may be key-value pairs corresponding to keys of the key-value pairs in the information set.
In this embodiment, the number of key-value pairs may be at least two. That is, the number of keys of the key-value pair in the information set associated with the object information of each object is at least two. The server acquires the expiration time corresponding to the key of each key value pair in the information set associated with the object information of the specified object, so as to conveniently determine whether the expiration time is reached or not in the following process.
In this embodiment, for each key of a key-value pair, the server determines whether the expiration time corresponding to the key of the key-value pair has been reached. Because the keys of the key-value pairs and the expiration times are correspondingly stored in the information set in a splicing mode, the expiration times can be obtained through the keys of the key-value pairs. And further determines whether the current time has reached the acquired expiration time.
Specifically, the server may traverse the key of each key-value pair in the information set, obtain the expiration time corresponding to each key through parsing, and determine whether the expiration time obtained through parsing has been reached.
In this embodiment, for each key of a key-value pair, the server responds after determining that the expiration time has not been reached: the key of the key-value pair and the value corresponding to the key of the key-value pair are deleted from the cache. That is, if it is determined that the expiration time has not been reached, the system does not perform an automatic deletion operation, but because a deletion request for the cached information is received, the server deletes the key of the key-value pair and the value in the key-value pair corresponding to the key of the key-value pair. In this way, cached key-value pairs may be deleted by their keys.
If the server determines that the expiration time has been reached, take the cache as a redis database as an example. The redis database in the server or the redis databases of other electronic devices in the device combination where the server is located may automatically delete the key-value pair in the cache region, where the expiration time value is set, after determining that the expiration time value is reached.
In this embodiment, after deleting the key-value pair in the cache region, the information set associated with the object information is deleted to empty all the cache information about the object in the cache region.
In the embodiment, when the expiration time is not reached, the key value pair associated with the object is deleted through the key of the key value pair in the information set associated with the object information, so that the information deletion is performed more accurately.

In this embodiment, the receiving unit 501 may receive the information storage request from the other electronic device by a wired connection manner or a wireless connection manner. Wherein the information storage request includes key-value pairs (key and value), an expiration time, and object information of the specified object. The key-value pairs, expiration times, and object information, which are typically included in an information storage request, are content associated with the same object. Here, the information storage request may include one piece of information, which is a group of related key value pairs, expiration time, and object information, or may include multiple pieces of information.
In this embodiment, the key value pair is the content to be stored by the electronic device. The setting unit 502 stores the key-value pair in the storage request into the buffer, and sets an expiration time value of the key-value pair stored in the buffer. The expiration time value is a value of an expiration time set in the cache. In particular, the value of the expiration time in the information storage request may be set to the expiration time value of the key-value pair in the cache. For example, the expiration time in the information storage request may be 2017/05/16, 01:02:30, which may be used as the expiration time value for the key-value pair in the cache.
In this embodiment, the storage unit 503 classifies the key and the expiration time of the key-value pair into the information set, and then stores the information set in the buffer. The information set is a set for collecting information and is associated with the object information. The object information of each object has an associated information set, and the object information of different objects is associated with different information sets.
