[0032] To address the aforementioned problems, this disclosure provides a data writing method, apparatus, device, medium, and vehicle. The following will first consider... Figures 1 to 2 The data writing method provided in the embodiments of this disclosure will be described in detail.
[0033] Figure 1 A flowchart illustrating a data writing method provided in an embodiment of this disclosure is shown.
[0034] In this embodiment of the disclosure, the data writing method can be performed by an electronic device. Specifically, the electronic device may include, but is not limited to, mobile terminals such as computer devices, mobile phones, in-vehicle devices, vehicle controllers, tablet computers, and wearable devices.
[0035] like Figure 1 As shown, the data writing method may include the following steps.
[0036] S110, Receive data write request.
[0037] In this embodiment of the disclosure, the electronic device can receive a data write request.
[0038] Alternatively, a data write request can be a request to write data to a storage device.
[0039] Specifically, electronic devices can receive data write requests.
[0040] S120. Obtain the real-time storage rate of the storage device and compare the real-time storage rate with the storage rate threshold.
[0041] In this embodiment of the disclosure, the electronic device can obtain the real-time storage rate of the storage device and compare the real-time storage rate with a storage rate threshold.
[0042] Alternatively, the storage device can be a device used to store data.
[0043] Optionally, the real-time storage rate can be a representation of the proportion of storage in real time of the storage device.
[0044] Optionally, the storage rate threshold can be a pre-set storage ratio. For example, the storage rate threshold can be 70%, 80%, etc., and there is no limitation here.
[0045] Specifically, electronic devices can obtain the real-time storage rate of storage devices and compare the real-time storage rate r with the storage rate threshold R.
[0046] S130. When the real-time storage rate is greater than the storage rate threshold, compress the data in the data write request to obtain the corresponding compressed data, and write the compressed data to the storage device.
[0047] In this embodiment of the disclosure, when the real-time storage rate is greater than the storage rate threshold, the electronic device can compress the data in the data write request to obtain the corresponding compressed data and write the compressed data to the storage device.
[0048] Alternatively, data compression can be the process of encoding the original data with less space, which means reducing the amount of data to reduce storage space without losing useful information.
[0049] Optionally, the compressed data can be the data obtained by compressing the original data.
[0050] Specifically, after comparing the real-time storage rate r with the storage rate threshold R, if the real-time storage rate r is greater than the storage rate threshold R, the electronic device compresses the data in the data write request to obtain the corresponding compressed data and writes the compressed data to the storage device.
[0051] Therefore, in this embodiment of the present disclosure, a data write request can be received, then the real-time storage rate of the storage device can be obtained, and the real-time storage rate can be compared with a storage rate threshold. Then, if the real-time storage rate is greater than the storage rate threshold, the data in the data write request can be compressed to obtain the corresponding compressed data, and the compressed data can be written to the storage device. Thus, by comparing the real-time storage rate with the storage rate threshold, data compression and writing can be performed when the real-time storage rate is high, thereby extending the lifespan of the storage device while ensuring data write performance.
[0052] Optionally, S110 may specifically include: receiving a data write request sent by the upper-layer interface and adding the data write request to the write request queue of the storage device buffer.
[0053] In this embodiment of the disclosure, the electronic device can receive a data write request sent by the upper-layer interface and add the data write request to the write request queue of the storage device buffer.
[0054] Optionally, the buffer can be a region for caching data.
[0055] Optionally, the write request queue can be a queue used to hold multiple data write requests.
[0056] Specifically, the electronic device can receive data write requests sent by the upper-layer interface and add the data write request to the write request queue of the storage device buffer.
[0057] Therefore, the received data write requests are added to the write request queue of the storage device's buffer, thereby buffering the data write requests, eliminating high-concurrency access peaks, and speeding up data processing.
[0058] Optionally, the data writing method may further include: statistically analyzing the data writing requests sent by the upper-layer interface within a preset time period to obtain statistical data; reducing the storage rate threshold when the statistical data decreases to the same level as the storage rate threshold; and increasing the storage rate threshold when the statistical data increases to the same level as the storage rate threshold.
[0059] In this embodiment of the disclosure, the electronic device can statistically analyze the data write requests sent by the upper-layer interface within a preset time period to obtain statistical data.
[0060] Optionally, the preset time can be a pre-set time. For example, the preset time can be 60s, 70s, etc., and there is no limitation here.
[0061] Optionally, the statistics can be used to characterize the number of data write requests within a preset time period.
[0062] Specifically, electronic devices can collect statistics on data write requests sent by upper-layer interfaces within a preset time period to obtain statistical data.
[0063] In some embodiments, the storage rate threshold is reduced when the statistical data decreases to the same level as the storage rate threshold.
[0064] Specifically, after obtaining statistical data, if the statistical data decreases and approaches the storage rate threshold R within a preset time, the electronic device can dynamically reduce the storage rate threshold. For example, the storage rate threshold R can be 50%, and it can be dynamically reduced by 10% or 20%, making the storage rate threshold R 40%, 30%, etc., without limitation here.
[0065] In other embodiments, the storage rate threshold is increased when the statistical data increases to the same level as the storage rate threshold.
[0066] Specifically, after receiving statistical data, if the statistical data increases and approaches the storage rate threshold R within a preset time, the electronic device can dynamically increase the storage rate threshold. For example, the storage rate threshold R can be 50%, and it can be dynamically increased by 10% or 20% to make the storage rate threshold R become 60% or 70%, etc., without limitation here.
[0067] Therefore, by dynamically adjusting the storage rate threshold, the impact on system performance when data compression is enabled can be effectively reduced, thus balancing performance and extending the lifespan of the storage medium.
[0068] Optionally, after adding the data write request to the write request queue of the storage device buffer, the data write method may further include: determining whether the data compression function is enabled; if the data compression function is enabled, compressing the data of the data write request in the write request queue to obtain the corresponding compressed data, and writing the compressed data to the storage device; if the data compression function is not enabled, obtaining the real-time storage rate of the storage device.
[0069] In this embodiment of the disclosure, the electronic device can determine whether to enable the data compression function.
[0070] Optionally, the data compression function can be performed via F2FS (Flash-Friendly File System).
[0071] Specifically, electronic devices can first determine whether data compression is enabled.
[0072] In some embodiments, when data compression is enabled, the data of the write request in the write request queue is compressed to obtain the corresponding compressed data, and the compressed data is written to the storage device.
[0073] Specifically, after determining whether the data compression function is enabled, if the electronic device determines that the data compression function is enabled, the electronic device can compress the data in the write request queue to obtain the corresponding compressed data and write the compressed data to the storage device.
[0074] In other embodiments, the real-time storage rate of the storage device is obtained without enabling data compression.
[0075] Specifically, after determining whether data compression is enabled, if the electronic device determines that data compression is not enabled, the electronic device can obtain the real-time storage rate of the storage device.
[0076] Optionally, S130 may specifically include: enabling data compression when the real-time storage rate is greater than the storage rate threshold; and when the data compression function is enabled, compressing the data of the write request in the write request queue to obtain the corresponding compressed data, and writing the compressed data to the storage device.
[0077] In this embodiment of the disclosure, when the real-time storage rate is greater than the storage rate threshold, the electronic device can enable the data compression function.
[0078] Specifically, after comparing the real-time storage rate with the storage rate threshold, if the electronic device determines that the real-time storage rate is greater than the storage rate threshold, it can enable the data compression function, that is, enable F2FS data compression.
[0079] Furthermore, with the data compression function enabled, the electronic device can compress the data in the write request queue to obtain the corresponding compressed data, and then write the compressed data to the storage device.
[0080] Optionally, after S120, the data writing method may further include: writing the data in the data writing request to the storage device when the real-time storage rate is less than or equal to the storage rate threshold.
[0081] In this embodiment of the disclosure, when the real-time storage rate is less than or equal to the storage rate threshold, the electronic device can write the data in the data write request to the storage device.
[0082] Specifically, the electronic device compares the real-time storage rate with the storage rate threshold. When it is determined that the real-time storage rate is less than or equal to the storage rate threshold, the electronic device can write the data in the data write request to the storage device.
[0083] Therefore, by setting a threshold to enable data compression, the lifespan of storage devices can be effectively extended while ensuring initial storage performance.

[0088] S220, Is data compression enabled?
[0089] In this embodiment of the disclosure, the electronic device can determine whether the data compression function has been enabled.
[0090] Specifically, the electronic device can first determine whether the data compression function is enabled. If the data compression function is enabled, then execute S230; if the data compression function is not enabled, then execute S240.
[0091] S230. Compress the data in the data write request.

[0093] S240, Obtain the real-time storage rate of the storage device.
[0094] In this embodiment of the disclosure, the electronic device can obtain the real-time storage rate of the storage device when the data compression function is not enabled.
[0095] S250, Is the real-time storage rate greater than the storage rate threshold?
[0096] In this embodiment of the disclosure, the electronic device can determine whether the real-time storage rate is greater than a storage rate threshold. If the real-time storage rate is greater than the storage rate threshold, then S260 is executed; if the real-time storage rate is less than or equal to the storage rate threshold, then S270 is executed.
[0097] S260, Enable data compression function.
[0098] In this embodiment of the disclosure, when the real-time storage rate is greater than the storage rate threshold, the electronic device can enable the data compression function, that is, it can enable F2FS data compression.
[0099] Furthermore, with the data compression function enabled, the electronic device can compress the data in the write request queue to obtain the corresponding compressed data, and then write the compressed data to the storage device.
[0100] S270, Write to storage device.
[0101] In this embodiment of the disclosure, when the real-time storage rate is less than or equal to the storage rate threshold, the electronic device can write the data in the data write request to the storage device.

[0107] The data writing module 330 can be used to compress the data in the data writing request when the real-time storage rate is greater than the storage rate threshold, obtain the corresponding compressed data, and write the compressed data to the storage device.
[0108] Therefore, in this embodiment of the present disclosure, a data write request can be received, then the real-time storage rate of the storage device can be obtained, and the real-time storage rate can be compared with a storage rate threshold. Then, if the real-time storage rate is greater than the storage rate threshold, the data in the data write request can be compressed to obtain the corresponding compressed data, and the compressed data can be written to the storage device. Thus, by comparing the real-time storage rate with the storage rate threshold, data compression and writing can be performed when the real-time storage rate is high, thereby extending the lifespan of the storage device while ensuring data write performance.
