The data reading method provided by the invention analyzes the received data reading request to obtain a target object identifier corresponding to target data to be read; searching a target object cache space corresponding to the target object identifier from the solid state disk; judging whether target data exist in the target object cache space; if yes, returning the target data from the solid state disk to the data reading end; if not, returning the target data from the mechanical hard disk to the data reading end; and if the target data is determined to be hot data, the target data is pulled up to the solid state disk. When it is determined that no target data exists in the target object cache space of the solid state disk, after it is determined that the target data to be read is hot data, the target data is pulled up to the solid state disk. The accuracy of judging the data heat is greatly improved, the data loading frequency is reduced, and the system performance is improved.
It should be noted that, based on the first embodiment, the embodiment of the present invention further provides a corresponding improvement scheme. In the following embodiments, steps that are the same as or correspond to those in the first embodiment may be referred to each other, and corresponding advantageous effects may also be referred to each other, which are not described in detail in the following modified embodiments.
Example two:

S202: and judging whether the target object identification exists in the current access list, if so, not processing, and if not, executing the step S203.
Presetting the time length of each access list as the current access list, for example, setting the time length as 5 minutes, when the time length of a certain access list as the current access list exceeds 5 minutes, inserting the access list into the historical access list, creating a new access list, and using the new access list as the current access list.
After the target object identifier corresponding to the target data to be read is obtained through analysis, whether the target object identifier exists in the current access list or not is judged, if yes, the fact that the target data are subjected to heat statistics is shown, no processing is needed, if not, the fact that the target data are not subjected to the heat statistics is shown, and step S203 is executed.
S203: and inserting the target object identification into the current access list.
And when the target object identification does not exist in the current access list, inserting the target object identification into the current access list, thereby realizing the heat statistics of the target data.
S204: and searching a target object cache space corresponding to the target object identifier from the solid state disk.
S205: and judging whether target data exists in the target object cache space, if so, executing step S206, and if not, executing step S207.
S206: and returning the target data from the solid state disk to the data reading end.
S207: and returning the target data from the mechanical hard disk to the data reading end.
S208: and acquiring the access hit rate of each access list of the target data in a preset period.
The period for deleting and updating the access list is preset, for example, statistics of 5 recent access lists is performed by taking statistics of 5 consecutive access lists as one period. After the target data is returned to the data reading end from the mechanical hard disk, the access hit rate of the target data in each access list in the preset period is obtained, specifically, the number of the target object identifiers in 5 access lists is obtained, and the ratio of the number of the target object identifiers in 5 access lists is used as the access hit rate of the target data in each access list in the preset period.
S209: and judging whether the access hit rate is higher than a preset value, if so, executing the step S210, and if not, not processing.
After the access hit rate of each access list of the target data in a preset period is obtained, whether the access hit rate is higher than a preset value or not is judged, if yes, the target data is hot data, and a high possibility of subsequent access exists, step S210 is executed, and if not, the target data is not processed if the probability of subsequent access is low. If the access hit rate threshold can be set to 60%, taking the above example into account, when it is determined that the number of target object identifiers in the 5 access lists is greater than or equal to 3, it indicates that the target data is hot data, and step S210 is performed.
S210: and pulling the target data from the mechanical hard disk to a target object cache space of the solid state disk.
And after the access hit rate is determined to be higher than the preset value, the target data is pulled up from the mechanical hard disk to a target object cache space corresponding to the target object identification in the solid state disk.
S211: and carrying out metadata information updating operation on the target object in the target object cache space.
And the target data is stored in the target object cache space by taking the target object as a unit.
After the target data are pulled from the mechanical hard disk to the target object cache space of the solid state disk, metadata information updating operation is carried out on the target object in the target object cache space, so that data searching and positioning can be carried out quickly during subsequent data access.
