Below, various embodiments will be described in more detail based on the above technical idea. The contents described above may be applied to various embodiments described below. For example, operations, functions, terms, etc. that are not defined in various embodiments described below may be performed and explained based on the contents described above.

In the following description, various embodiments are described on the premise that the server device 100 processes the cache update operation. According to various embodiments, the manager device 200 performs the cache update of the server device 100. Various information related to the performed operation may be transmitted and received with the server device 100.

According to FIG. 3, the server device 100 performs an update on the cache, and as an operation for this, obtains information about the update completion time set by the user for updating the cache ( 301), check the update time for the cache (303), and based on the update completion setting time and the update time, determine the update start setting time for the cache (305), and based on the update start setting time, A first update to the cache may be performed (307).

According to FIG. 3, the operation of the server device 100 to update the cache may be to update the cache associated with storage where various data to be processed in the service provided by the server device 100 are stored. , In this case, the service may correspond to a service that allows multiple users using the service to order and purchase multiple items sold in the service. The plurality of items sold in the service are not limited to the type or type of the item and may include various types or types of items registered by the seller to sell the item.

The cache receives and stores data from storage, and when a data call is confirmed from a device such as the server device 100, the cache transmits the stored data to the device. The cache can be updated by receiving data from storage at a certain point in time according to a certain update cycle, and separately from the time according to a preset update cycle, it receives new data from storage at a time according to the settings of the administrator or user, as in the present invention. It can be set to be updated.

According to various embodiments, in operation 301, the server device 100 may obtain information about the update completion setting time point set by the user to update the cache.

For example, the user who sets the update completion setting time point in operation 301 may be an administrator or user corresponding to the manager device 200, and the update completion setting time point includes an update or cache already set for the cache. Separate from the updates managed in the data processing system, this may correspond to the time when the user settings update is scheduled to be completed for updating user settings that the user sets on his or her own or separately. Accordingly, operation 301 of the server device 100 may correspond to an operation in which the server device 100 obtains information about the expected update completion time set by the user from the manager device 200. Additionally, the first update that the server device 100 performs on the cache according to operation 307 may correspond to an update of user settings.

For example, the update completion setting point in operation 301 is the time when the user wants the update of the cache to be completed, and when the server device 100 obtains the typical time required to update the cache, the server device 100 It is possible to manage the update to be completed at the time of setting the update completion by starting the update of the cache at a point in time prior to the time required for the update completion setting.

For example, if the update of the cache is set to be completed according to the update completion setting point in operation 301, the data stored in the cache may vary before/after the update completion setting time, and a request to confirm data to the cache is made according to the update completion setting time. The data confirmed in the cache may vary depending on whether it is received before or after the update completion point. In this regard, the server device 100 may perform an operation to check data by comparing the time when the data confirmation request is received and the time when the update completion is set, as shown in FIG. 4.

In Figure 4, server device 100 may receive a request to confirm specific data for the cache (401). At this time, such a specific data confirmation request may be a request obtained from a user, administrator, and/or other entity wishing to check data stored in the storage, and may be a request obtained from a user, administrator, and/or other entity wishing to check data stored in the storage, and the data stored in the storage may also be stored in the cache. In this case, it may correspond to a request to check the data in the cache.

When receiving a specific data confirmation request for the cache, the server device 100 may check when the specific data confirmation request was received (403), and when the specific data confirmation request was received and when the user Data corresponding to the specific data confirmation request can be confirmed by comparing the set update completion setting time point (405).

In summary, when the server device 100 receives a specific data confirmation request for the cache, the server device 100 can confirm when the specific data confirmation request was received, and the specific data confirmation request is received. It can be set to check the data corresponding to the specific data confirmation request by comparing the received time and the update completion setting time.

If the time at which the specific data confirmation request is received is before the update completion setting time, the server device 100 determines that a data confirmation request has been received for the cache before the update, and determines that the data confirmation request is received at the update completion setting time. Existing data stored in the cache before the update is performed can be set to be confirmed in response to the specific data confirmation request.

On the other hand, if the time at which the specific data confirmation request is received is after the update completion setting time, the server device 100 determines that a data confirmation request has been received for the cache after the update, and the server device 100 determines that a data confirmation request has been received for the cache after the update, and the server device 100 determines that the data confirmation request is received at the update completion setting time. The updated data stored in the cache after the update is performed can be set to be confirmed in response to the specific data confirmation request.

According to various embodiments, in operation 303, the server device 100 may check the time required to update the cache.

For example, the time required to update the cache checked by the server device 100 in operation 303 may be obtained based on the time typically taken to update the cache. As an example, the update time may be obtained as a value corresponding to the update time required for the last update of the cache. As another example, the update time may be obtained as a value corresponding to the average time required for a plurality of updates corresponding to the update history performed on the cache.

According to various embodiments, in operation 305, the server device 100 may determine an update start setting time for the cache based on the update completion setting time and the update required time.

For example, the update start setting time for the cache determined by the server device 100 in operation 305 is the update completion setting time obtained by the server device 100 in operation 301 and the server device 100 in operation 303. It may correspond to a point in time as old as the update time confirmed by. That is, when the server device 100 starts the first update at the update start setting time determined according to operation 305, the first update takes as much time as the update time, so that the first update is completed at the update completion setting time. You can.

For example, the first update managed to be completed at the update completion setting point may be triggered by a data confirmation request received for the cache after the update start setting point determined by the server device 100 in accordance with operation 305. You can. That is, if there is a request to check data received for the cache, the first update set by the user for the cache may be triggered to start. In addition, considering that it may take time to receive a data confirmation request for triggering the first update, the first update may be managed and set to be completed within a certain time period including the update completion setting point. there is.

For example, the first update set by the user for the cache may be triggered by the first data confirmation request received for the cache after the update start setting time. In other words, a plurality of data confirmation requests may be received for the cache, but the update for the cache can be set to be started by the first data confirmation request received for the cache after the update start setting time. For such settings, the server device 100 may utilize flag information.

As an example, the server device 100 sets flag information for checking whether the cache is being updated, and when a data confirmation request is received for the first time for the cache after the update start setting point, the server device 100 flags the cache. By setting the value of the information to '1', you can indicate a flag that the cache update is currently in progress. On the other hand, if the cache update is not in progress because no data confirmation request has been received, the server device 100 may set the value of the flag information to '0' to indicate a flag that the cache update is not currently in progress. there is. If the value of the flag information is set to '1' according to the above method, the server device 100 responds to another data confirmation request additionally received for the cache after the first data confirmation request for the cache after the update start setting time. You can set it so that updates to the cache are not triggered.

For example, if no data confirmation request is received for the cache after the update start setting point determined by the server device 100 in operation 305, the first update corresponding to the user setting update may not be triggered. In this case, the cache is not updated by the first update corresponding to the user-set update, but can be updated by an update preset for the cache or an update managed on the data processing system.

According to various embodiments, in operation 307, the server device 100 may perform a first update on the cache based on the update start setting time.

For example, the various embodiments described above in operations 301 to 305 may be used when the server device 100 performs a first update to the cache in operation 307.

Meanwhile, when the server device 100 performs the first update according to operation 307, the server device 100 updates the cache so that it can be newly updated after the first update expires, corresponding to the first update. The operation of newly managing updates to the cache by setting an expected cache expiration time can also be performed as shown in FIG. 5.

In FIG. 5 , the server device 100 can confirm that the first update according to operation 307 is set to be performed at the time when the update completion according to operation 301 is set (501). After confirming that the first update is set to be performed, the server device 100 needs to set a valid period for the first update and manage a new update to the cache thereafter, so it responds to the first update after the update completion setting point. You can set the expected cache expiration point (503). When the cache expiration time is set, the validity period of the first update can be confirmed as until the cache expiration time, and the server device 100 sets a new update to the cache to be performed after the cache expiration time (505), After the first update is performed, the cache can be managed to be newly updated after a certain period of time has passed.

For example, the scheduled cache expiration time set by the server device 100 in response to the first update according to operation 503 may be set to have a certain time interval from the update completion setting time that is managed so that the first update is completed. In this case, the constant time interval may be a time interval set by the manager or user corresponding to the manager device 200. That is, an administrator or user who sets an update completion setting time point that manages the first update to be completed can set a cache expiration time point that allows a new update to be performed after a certain time interval after the first update is completed. As an example, the cache expiration time may be set to have a time interval of 1 minute, 2 minutes, 3 minutes, etc. from the time the update completion is set. As another example, the scheduled cache expiration time may be set to have a time interval corresponding to the time interval from the update completion setting time to the current update completion setting time.

For example, the scheduled cache expiration time set by the server device 100 in response to the first update according to operation 503 may be set to have a random time interval from the update completion setting time that is managed so that the first update is completed. In this case, the arbitrary time interval may be a time interval randomly determined based on a random function. In other words, the administrator or user who sets the update completion setting time point managed so that the first update is completed can set the cache expiration time point so that a new update can be performed after the first update is completed and a randomly set time interval. . When the cache expiration time is set to a random time interval from the update completion setting point, the time interval set between the update completion setting point and the cache expiration point is set too short, causing the update to be repeated unnecessarily. may occur, or the time interval between the update completion point and the scheduled cache expiration point may be set too long, causing a problem in which the update is not performed on time. To this end, the server device 100 sets a minimum time interval value and a maximum time interval value that can set the time interval between the update completion setting point and the cache expiration point, and sets the minimum time interval value and the maximum time interval value between the minimum time interval value and the maximum time interval value. It can also be set to determine a random time interval according to a random function.

For example, the time interval between the update completion setting point and the cache expiration point may be set based on the number of data requests confirmed for the cache. In other words, if the number of data requests confirmed for the cache in the time interval between the update completion setting point and the scheduled cache expiration point is large, it may be appropriate to update the cache after completing the data confirmation corresponding to the data request, so the cache You can also set the time interval between the update completion point and the cache expiration point according to the number of data requests confirmed. For example, if the number of data requests confirmed for the cache is N, the time interval is set to 1 minute, and if the number of data requests confirmed for the cache is 2N, the time interval is set to 2 minutes, etc. The number of data requests is constant. The time interval can also be set to increase at regular intervals whenever it increases.

For example, the time interval between the update completion point and the cache expiration point can be set in consideration of the characteristics of the data stored in the cache. If the data stored in the storage associated with the cache corresponds to data that is judged to need to be updated in real time, and the cache is managed to store such data, the time between the update completion setting and the scheduled cache expiration The interval is set short, so the cache is updated more frequently, allowing more real-time data to be stored. On the other hand, if the data stored in storage linked to the cache corresponds to data that is judged not to need to be updated in real time and the cache is managed to store such data, the time between the update completion setting point and the scheduled cache expiration time The time interval is set long to reduce the load due to cache updates.

For example, in the case where a second update that is different from the previous first update is managed to be performed after the cache expiration point, such a second update is performed by a data confirmation request received for the cache after the cache expiration point. It can be triggered and performed. The server device 100 may perform a second update if there is a request to confirm data received for the cache after the cache expiration time. At this time, similar to the first update described above, the server device 100 may perform a second update on the cache after the cache expiration time. The second update may be triggered by the first received data confirmation request. That is, a plurality of data confirmation requests may be received for the cache, but the second update for the cache is set to be started by the first data confirmation request received for the cache after the cache expiration time, so that the server device 100 A second update may be performed based on the first data confirmation request received for the cache after the scheduled cache expiration time.

For example, considering that the cache expiration time corresponds to the time when the first update corresponding to the user settings update set by the user is valid, the server device 100 may Data verification can be set to stop even if there is a data verification request for the cache until the second update is completed. That is, in a situation where the first data confirmation request is received after the scheduled cache expiration time and the second update is in progress, the server device 100 responds to other data confirmation requests received for the cache until the second update is completed. You can set it to stop checking data.

Alternatively, the server device 100 may be set so that the interruption of data confirmation as described above is conditional. That is, the server device 100 can be set to stop data confirmation when there are many data confirmation requests or when latency is expected to occur in data confirmation processing. For example, if data confirmation is set to stop in all cases where the second update is performed, a situation may occur where data is not confirmed unnecessarily, so the server device 100 may make the first data confirmation request after the cache expiration point. In a situation where a second update is received and in progress, if the number of other data confirmation requests received for the cache for a certain period of time after the first data confirmation request is more than a threshold number, the number of requests received for the cache until the second update is completed You can set it to stop data verification in response to other data verification requests.

An operation in which the server device 100 performs an update on the cache according to FIGS. 3 to 5 may appear as shown in FIG. 6 .

At 601, the server device 100 sets the update time required for the last update of the cache, or Based on the cache's past update history, the update start point (start refresh) can be determined considering the normal update time (last execution time) found to be necessary for the cache update. In other words, when a data confirmation request for the cache is received after the update start setting point (start refresh), the update of the user settings for the cache may begin, and the time period that includes the update completion setting point (user setting) set by the user ( The update of user settings can be completed in the refreshed range.

Additionally, in order to set a valid period for such updates of user settings and manage new updates to the cache, the server device 100 may set a cache expiration point (redis cache expire) as shown in 603. . If a request to confirm data about the cache is received after the cache expiration point, the cache may be newly updated. In 603, you can see that the cache expiration time (redis cache expire) is set 3 minutes after the update completion time (user setting).

It is obvious that in the process of performing the operation method according to FIGS. 3 to 6, each piece of information provided by the server device 100 may be combined and provided in various forms.
