Detailed Description
The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. All other embodiments obtained by a person of ordinary skill in the art based on the embodiments in the present application without making any creative effort belong to the protection scope of the present application.
At present, a data holding processing method is mainly used for monitoring the continuous opening or continuous closing time of each block, then judging whether the continuous opening or continuous closing time of each block reaches the data holding time, and carrying out data holding processing on the blocks reaching the data holding time, so that a large number of processes are occupied in the system operation process to monitor the continuous opening or continuous closing time of each block, system process resources are caused, frequent data holding processing is caused during operation, and system performance is reduced. In view of this, the present application provides a solid state disk data processing method, which can save system process resources, perform data retention processing on blocks in batches, improve data retention processing efficiency, and improve system performance.
Referring to fig. 1, an embodiment of the present application discloses a method for holding data in a solid state disk, where the method includes:
step S11: and setting the data holding time of the block in the Flash.
In a specific real-time process, the data retention time of the block in Flash needs to be set first. Specifically, data holding time of the block needs to be set according to the actual performance of the Flash and the like so as to judge whether corresponding data holding processing needs to be performed on the block, wherein the data holding time includes a maximum opening time and a maximum closing time, the maximum opening time is the maximum time for continuously opening the block, and the maximum closing time is the maximum time for continuously closing the block.
Step S12: and determining a target information recording table for recording the block information of the block according to the latest operation type of the block.
In a specific implementation process, after the data holding time of the block in the Flash is set, a target information recording table for recording the block information of the block is determined according to the latest operation type of the block. Wherein the recent operation types include two types of on operation and off operation.
Step S13: and according to a first time difference between the latest operation time of the block and the system starting time, determining a target information recording sub-list actually used for recording the block information from the target information recording table, and recording the block information in the target information recording sub-list, wherein the target information recording sub-list is provided with a corresponding time identifier, and the first time difference is matched with the time identifier.
In this embodiment, a target information record sub-list actually used for storing the block information needs to be determined from the target information record table according to a first time difference between the latest operation time of the block and a system start time, and the block information is recorded in the target information record sub-list, where the target information record sub-list has a corresponding time identifier, and the first time difference needs to be matched with the time identifier.
In a specific implementation process, the time indicator may be a period of time interval, and the time indicated by the time indicator may be a maximum value of the time interval or an average value of the time interval. When the time indication may be a time interval, the first time difference should belong to the time interval. For example, if the time stamp corresponding to the target information sub-list is 1 to 5 seconds after the system is started, the time represented by the time stamp may be set to be the 5 th second after the system is started, and the block information with the first time difference smaller than or equal to 5 seconds is stored in the target information sub-list, that is, the block information corresponding to the block which is opened and closed within 1 to 5 seconds after the system is started is recorded in the target information sub-list.
Step S14: and determining a second time difference between the current time and the time represented by the time mark, and judging whether the second time difference is larger than or equal to the data holding time.
It will be appreciated that after recording the block information into the target information recording sub-list, a second time difference between the current time and the time represented by the time stamp needs to be determined. And when the time mark is a period of time interval and the time represented by the time mark is the maximum value of the time interval, determining the difference value between the current time and the maximum value to obtain the second time difference. For example, the current time is the 7 th second after the system is started, the time identifier corresponding to the target information recording sub-list is 1-5 seconds after the system is started, the time represented by the time identifier is the 5 th second after the system is started, and then the second time difference between the current time and the time represented by the time identifier is 2 seconds. After the second time difference is determined, it is further required to determine whether the second time difference is greater than or equal to the data retention time.
Step S15: and if the second time difference is greater than or equal to the data holding time, performing data holding processing on all the blocks corresponding to the block information recorded in the target information recording sub-list.
In a specific implementation process, if the second time difference is greater than or equal to the data holding time, performing data holding operation on all blocks corresponding to the block information in the target information recording sub-list.
Therefore, the data retention time of the block in the Flash needs to be set firstly; determining a target information recording table for recording the block information of the block according to the latest operation type of the block; determining a target information recording sub-list actually used for recording the block information from the target information recording table according to a first time difference between the latest operation time of the block and the system starting time, and recording the block information in the target information recording sub-list, wherein the target information recording sub-list is provided with a corresponding time identifier, and the first time difference is matched with the time identifier; then determining a second time difference between the current time and the time represented by the time identifier, and judging whether the second time difference is greater than or equal to the data holding time; and if the second time difference is greater than or equal to the data holding time, performing data holding processing on all the blocks corresponding to the block information recorded in the target information recording sub-list. When the second time difference is greater than or equal to the data holding time, it can be determined that all the blocks corresponding to the block information in the target information recording sub-list are subjected to data holding processing, so that system process resources are saved, data holding processing is performed on the blocks in batches, data holding processing efficiency is improved, and system performance is improved.

step S21: and setting the maximum opening time and the maximum closing time of the block in the Flash so as to set the data holding time of the block.
In this embodiment, the maximum opening time and the maximum closing time of a block in Flash need to be set to set the data holding time of the block, and the maximum opening time and the maximum closing time may be different according to an actual situation.
Step S22: and if the latest operation type of the block is opening operation, determining an information recording table corresponding to the opening operation as a target information recording table for recording the block information of the block.
In a specific implementation process, the latest operation type of the block comprises an opening operation and a closing operation, and if the latest operation of the block is the opening operation, an information recording table corresponding to the opening operation is determined as a target information recording table for recording block information of the block.
Step S23: and according to a first time difference between the latest operation time of the block and the system starting time, determining a target information recording sub-list actually used for recording the block information from the target information recording table, and recording the block information in the target information recording sub-list, wherein the target information recording sub-list is provided with a corresponding time identifier, and the first time difference is matched with the time identifier.
Step S24: and determining a second time difference between the current time and the time represented by the time identifier, and judging whether the second time difference is greater than or equal to the maximum opening time length so as to judge whether the second time difference is greater than or equal to the data holding time.
It is understood that, when the latest operation of the block is an opening operation, after the second time difference is determined, it is required to determine whether the second time difference is greater than or equal to the maximum opening duration, so as to determine whether the second time difference is greater than or equal to the data holding time.
Step S25: and if the second time difference is greater than or equal to the maximum opening duration, closing all the blocks corresponding to the block information recorded in the target information recording sub-list.
In a specific implementation process, if the second time difference is greater than or equal to the maximum opening duration, closing all blocks corresponding to the block information recorded in the target information recording sub-list.
For example, if the maximum starting duration is 10 minutes, the time identifier corresponding to the target information recording sub-list is 1-5 minutes after the system is started, the time represented by the time identifier is 5 minutes after the system is started, and the current time is 15 minutes after the system is started, the second time difference is 10 minutes, and the second time difference is equal to the maximum starting duration, and it is necessary to close all the blocks corresponding to the block information in the target information recording sub-list.
Referring to fig. 3, an embodiment of the present application discloses a specific method for holding data of a solid state disk, where the method includes:
step S31: setting the maximum opening time and the maximum closing time of the block in Flash to set the data holding time of the block.
Step S32: and if the latest operation type is closing operation, determining an information recording table corresponding to the closing operation as a target information recording table for recording the block information of the block.
In a specific implementation process, the latest operation type of the block comprises an opening operation and a closing operation, and if the latest operation type is the closing operation, an information recording table corresponding to the closing operation is determined as a target information recording table for recording block information of the block.
Step S33: and according to a first time difference between the latest operation time of the block and the system starting time, determining a target information recording sub-list actually used for recording the block information from the target information recording table, and recording the block information in the target information recording sub-list, wherein the target information recording sub-list is provided with a corresponding time identifier, and the first time difference is matched with the time identifier.
Step S34: and determining a second time difference between the current time and the time represented by the time identifier, and judging whether the second time difference is greater than or equal to the maximum closing time length so as to judge whether the second time difference is greater than or equal to the data holding time.
It is understood that when the latest operation of the block is a closing operation, after the second time difference is determined, it is required to determine whether the second time difference is greater than or equal to the maximum closing time length, so as to determine whether the second time difference is greater than or equal to the data holding time.
Step S35: and if the second time difference is greater than or equal to the longest closing time, moving all the blocks corresponding to the block information recorded in the target information recording sub-list.
In a specific implementation process, if the second time difference is greater than or equal to the longest closing time, moving all the blocks corresponding to the block information recorded in the target information recording sub-list. Specifically, if the second time difference is greater than or equal to the maximum closing time length, moving the data in the block corresponding to the block information in the target information recording sub-list to other blocks to avoid data loss.
Referring to fig. 4, an embodiment of the present application discloses a solid state disk data holding apparatus, including:
