Detailed Description
The application is described in further detail below with reference to the drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the application and are not limiting thereof. It should be further noted that, for convenience of description, only some, but not all of the structures related to the present application are shown in the drawings. Embodiments of the application and features of the embodiments may be combined with each other without conflict.
Example 1
Fig. 1 is a flowchart of steps of a data processing method according to an embodiment of the present invention, where the embodiment of the present invention is applicable to a case of calculating an instantaneous balance of a user at a specified time point, and the method may be performed by a data processing apparatus according to an embodiment of the present invention, where the data processing apparatus may be implemented by hardware or software, and integrated into an electronic device according to an embodiment of the present invention, and specifically, as shown in fig. 1, the data processing method according to an embodiment of the present invention may include the following steps:
s101, when the balance of the account is changed, obtaining the balance change time when the balance is changed and the balance value after the balance is changed.
In the embodiment of the invention, the balance of the account can be the currency balance or the virtual gold coin balance after currency is exchanged into the virtual gold coin. For the balance of the account, when the balance of the account is consumed or recharged by a user, the balance of the account is changed, the system records the time when the balance is changed and the changed balance value, in practical application, the system can form account running water, the account running water records the balance change history of the account, the running water of the account can be monitored, when newly added running water is monitored, the balance value in the newly added running water is obtained as the changed balance value, and the timestamp in the running water is the balance change time.
In a preferred embodiment, a balance table may be established for the account, where the balance table may be a table recording a balance change time and a changed balance value of the account, and when the balance table is newly recorded, the balance is changed, and the balance change time and the changed balance value when the balance is changed may be obtained from the balance table.
Of course, in practical application, a person skilled in the art can record the change of the balance according to the change of the balance, so as to obtain the balance change time and the balance value after the balance change by adopting different methods.
S102, determining the cycle starting time of the balance period to which the balance change time belongs.
In the embodiment of the invention, the balance of the account can be checked and checked, and the check period can be in units of month, day and hour, and can be 1 month, 1 day or 1 hour, and the period duration of the check period is not limited in the embodiment of the invention.
The cycle start time is the starting time of each balance cycle, or may be the deadline of the account balance acquired by the user, in one example, the balance cycle is 1 month, when the balance of the account on 1 day 00:00:00 of each month needs to be acquired, the cycle start time is 00:00:00 of 1 day of each month, and similarly, the balance cycle is 1 day, the cycle start time is 00:00:00 of each day, the balance cycle is 1 hour, and the cycle start time is 0 minute and 0 second of each hour.
When the balance of the account is changed, the cycle start time of the balance cycle to which the balance change time belongs when the balance is changed can be determined. In one example, the balance period is 1 day, if the balance of an account a changes in the balance of 25 days 07:15:23 of 25 days 2020, the balance change time 2020 is a period start time of the balance period belonging to 25 days 07:15:23 of 2020, the balance of an account a changes in the balance of 25 days 17:10:03 of 2020, and the balance change time 2020 is a period start time of the balance period belonging to 25 days 00:00:00 of 2020.
In an alternative embodiment of the present invention, the balance change time may be a balance change timestamp generated when the balance changes, a time difference from a cycle start timestamp of the first balance period to the balance change timestamp may be calculated first, a ratio of the time difference to a preset cycle duration is calculated and rounded down to obtain a cycle number, a product of the cycle number and the preset cycle duration is calculated, and a cycle start time of the balance cycle to which the balance change timestamp belongs is obtained by summing a value of the product and the start timestamp of the first balance period, where the cycle start time is a cycle start time of the balance cycle to which the balance change time belongs.
S103, updating the balance value of the account at the period starting time in a preset period balance table into the balance value, wherein in the preset period balance table, when the account and the period starting time are used for acquiring the balance of the account at the appointed period starting time, the balance value of the account at the period starting time before the appointed period starting time is used as the balance value of the account at the appointed period starting time.
In particular, the periodic balance table may be a table in which accounts, period start times, and balance values are recorded, and in one example, one periodic balance table may be generated for each account, where the periodic balance table records balance values of the account at the period start times of the respective balance periods, and of course, one periodic balance table may also record balance values of a plurality of accounts at the period start times of the respective balance periods. After determining the period starting time of the balance period to which the balance change time belongs, the balance value can be replaced by the balance value corresponding to the period starting time in the period balance table. Of course, if there is no account balance value in the periodic balance table at the period start time, the period start time and balance value may be inserted into the periodic balance table, thereby obtaining the account balance value at the period start time.
In practical applications, when the balance of the account needs to be acquired at the designated cycle start time in response to the balance acquisition request, the balance value at the time of the cycle start time before the designated cycle start time is taken as the balance acquisition result, and the balance period is 1 day, for example, when the balance of the account a at the time of 25 days in 2020, 00:00:00 (designated cycle start time) needs to be acquired, the balance value of the account a at the time of 24 days, 00:00 (the time of the cycle start time before) in 2020, in the balance table, can be taken as the balance of the account a at the time of 25 days, 00:00 in 2020.
In another example, when balance of all accounts at the designated cycle start time is required to be acquired for balance operation, the balance values of all accounts in the cycle balance table at the period start time before the designated cycle start time are summed to obtain the balance value.
When the balance of the account is changed, the balance change time and the balance value after the balance change are obtained, after the period starting time of the balance period to which the balance change time belongs is determined, the balance value of the account at the period starting time in the preset period balance table is updated to the balance value, so that the balance value of the account at the designated period starting time is obtained, the balance value of the balance at the period starting time before the designated period starting time is used as the balance value of the account at the designated period starting time through searching the period balance table, a lock table is not needed to be carried out on the balance table, other services related to the balance table are not influenced, the balance value of the corresponding period starting time in the period table is changed after the balance change of the account is monitored, the real instantaneous balance value of the account at the designated period starting time can be obtained through the period balance table, the balance value of the account is not required to be confirmed through running water back, the operation time and the space complexity of the period balance table is low, and the efficiency of obtaining the instantaneous balance table is improved.
Example two
Fig. 2 is a step flow chart of a data processing method provided in a second embodiment of the present invention, where the data processing method in the first embodiment of the present invention is optimized based on the first embodiment, specifically, as shown in fig. 2, the data processing method in the embodiment of the present invention may include the following steps:
s201, monitoring the balance of the account to determine whether the balance of the account changes.
In practical application, when the account has consumption or recharging operation, the balance of the account can be changed, the balance of the account can be monitored in real time, in one example, the balance of the account can be obtained according to a preset period, the balance of the account is determined to be changed when the balances obtained in two adjacent periods are not equal, in another example, the balance of the account is determined to be changed when the account is newly added and recorded, or the balance of the account is determined to be changed when a record is newly added in a balance list for recording the balance change of the account. The person skilled in the art may monitor the balance of the account in any way to determine whether the balance of the account has changed, and execute S202 when the balance of the account has changed, otherwise continue to monitor the balance of the account.
S202, obtaining the balance value after the balance change and a balance change time stamp generated when the balance is changed.
In the embodiment of the invention, when the balance of the account is changed, the system records the changed balance value and generates a time stamp, wherein the time stamp is the balance change time stamp, and the balance change time stamp is the time when the balance is changed. In one example, a running water is generated after the balance of the account is changed, and the running water at least comprises a balance value after the change and a balance change time stamp when the balance is changed.
S203, calculating the cycle starting time of the balance change time stamp belonging to the balance change period by adopting the cycle starting time stamp of the first balance change period, the balance change time stamp and the preset cycle duration.
In an alternative embodiment of the present invention, the balance change time is a balance change timestamp generated when the balance changes, a time difference from a cycle start timestamp of the first balance cycle to the balance change timestamp may be calculated, a ratio of the time difference to a preset cycle duration is calculated and rounded down to obtain a cycle number, a product of the cycle number and the cycle duration is calculated, and a cycle start time of the balance change cycle is obtained by summing a value of the product and the start timestamp of the first balance cycle.
Specifically, assuming that the period start time stamp of the first balance period is S 0, the period duration is T, and the balance change time stamp is n, the period start time Stime of the balance change period to which the balance change time stamp belongs may be calculated by the following formula:
Stime＝int((n-S0)/T)×T+S0
where int () is a downward rounding function.
The following describes the process of calculating the cycle start time with a balance cycle of 1 day as an example, assuming that the running water of user a at 08 in 2020 is in the following balance:
| User ID | Balance change time stamp | Balance value |
| A | 08 And 01 of 2020:09:30:01 | 100 |
| A | 2020, 08, 01 And 19:00:00 | 50 |
| A | 08, 02, 10:01:08 In 2020 | 70 |
| A | 08 And 03 days of 2020, 20:07:08 | 80 |
| A | 08, 03, 23:01:08 In 2020 | 100 |
The cycle start time stamp S 0 of the first balance cycle is 2020, 08, 01, 00 and 00, and the preset cycle time T is 24 hours, then:
When the balance change time stamp n is 09:30:01 on the 08 th month 01 of 2020, the time difference between the balance change time stamp n and the cycle start time stamp S 0 (00:00 on the 08 th month 01 of 2020) of the first balance period is 9.5 hours, the ratio of the time difference to the preset cycle duration is 9.5/24, the ratio is rounded down to the whole cycle number of 0, and the cycle start time Stime of the balance change time stamp n is the balance change time stamp of 09:30:01 on the 08 th month 01 of 2020, and the cycle start time Stime of the balance period is 00:00 on the 08 th month 01 of 2020;
When the balance change time stamp n is 19:00:00 on the 01 st day of the 2020 month, the time difference between the balance change time stamp n and the cycle start time stamp S 0 (the 01 st day of the 2020 month, 00:00) of the first balance period is 19 hours, the ratio of the time difference to the preset cycle duration is 19/24, the ratio is 0 when the whole cycle number is rounded down, and the cycle start time Stime of the balance change time stamp n of the balance period which belongs to the 19:00:00 on the 01 st month of the 2020 month is 00:00 on the 01 st month of the 2020 year 08 month;
when the balance change time stamp n is 10:01:08 on 02 th of 2020, the time difference between the balance change time stamp n and the cycle start time stamp S 0 (00:00 on 01 th of 2020) of the first balance period is 34 hours, the ratio of the time difference to the preset cycle duration is 34/24, the ratio is 1×24+s 0, the downward rounding cycle number is 1, the balance change time stamp n is the second balance period start time after the first balance period start time, namely, the cycle start time Stime of the balance period which belongs to the balance change time stamp n is 10:01:08 on 02 th of 2020 is 00:00 on 02 th of 2020;
By analogy, the period start time Stime of the balance period to which the balance change timestamp n belongs when the balance change timestamp n is 20:07:08 on the 08 th month 03 on the 2020 is 00:00:00 on the 08 th month 03, the period start time Stime of the balance change time stamp n is the balance period to which the year 2020, month 03, 23:01:08 belongs is the year 2020, month 03, 00:00.
In practical application, the period duration of the balance time period may be not limited, and in addition, a person skilled in the art may set the period start time of the balance time period according to the actual requirement, for example, the period start time is set to be 18:00:00 per day, furthermore, the balance time period to which the balance change timestamp belongs may be directly determined through time logic, and the period start time is determined through the belonging balance time period, for example, in the above example, the period start time is set to be 2020, the period start time is 2020, 08, 03, and the period start time is 2020, 08, 03, 00:00:00, and the embodiment of the present invention does not limit the period start time of the balance change timestamp.
S204, judging whether a balance value of the account at the period starting time exists in the preset period balance table.
In an alternative embodiment of the present invention, a periodic balance table may be preset, and the preset periodic balance table is initialized, where the initialization may be to initialize each field in the periodic balance table and determine an initial value of each field, and in one example, a table structure of the periodic balance table is as follows:
| Field name | Meaning of field |
| Uid | User ID |
| Stime | Cycle start time |
| Count | Balance value |
During initialization, an account, the period starting time of the first balance period and the initial balance value can be written into the periodic balance table, in one example, the balance tables of all existing users can be pulled, and the account and the balance value in the balance table are imported into the preset periodic balance table to finish initialization. Inserting new period starting time and updating balance value along with the time, judging whether the balance value of the account at the determined period starting time exists in the preset period balance table after the balance is changed and the period starting time of the balance period to which the balance change time stamp belongs is determined, if so, executing S205, otherwise, executing S206.
S205, updating the balance value of the account in the preset period balance table at the period starting time to be the balance value.
For the period starting time of the balance period to which the balance change time stamp belongs, if the balance value of the account at the period starting time exists in the preset period balance table, replacing the balance value of the account at the period starting time in the preset period balance table by the current monitored balance value after change.
S206, inserting the balance value into the preset period balance table as a balance value of the account at the period starting time.
For the period starting time of the balance period to which the balance change time stamp belongs, if the balance value of the account at the period starting time does not exist in the preset period balance table, inserting the period starting time into the preset period balance table, and setting the balance value of the inserted period starting time to be the monitored balance value after change.
In order to make the embodiments of the present invention more clearly understood by those skilled in the art, the following description will illustrate the updating process of the balance value by way of example:
Taking account a as an example, the balance period is 1 day, the period start time of each balance period is 00:00:00 per day, and the partial flow of user a is as follows (balance change):
The balance of 01:00:00 of the year 2020, 08 and 01 is 18 yuan;
the balance of 07:00:00 in the year 2020, 08 and 01 is 108 yuan;
the balance of 12:00:00 in 01 of 08 in 2020 is 100 yuan;
The balance of 21:00:00 in the year 2020, 08 and 01 is 30 yuan;
the balance of 23:00:00 in the year 2020, 08 and 01 is 40 yuan;
60 yuan for the balance of 02:00:00 of 02:02 of 2020 month,
The balance of 10:00:00 in 02 of 2020 is 80 yuan,
The balance of 21:00:00 on 02 of 08 in 2020 is 101 yuan,
The balance of the balance is unchanged in the year 08 and 03 in 2020;
10 yuan is the account balance of 10:00:00 points on 04 th month in 2020.
The process of updating the preset periodic balance table is as follows:
08 month 01 day 01:00:00, uid=a, stime =1 day 00:00:00, count=18;
08 month 01 day 07:00:00, uid=a, stime =1 day 00:00:00, count=108;
08 month 01 day 12:00:00, uid=a, stime =1 day 00:00:00, count=100;
08 month 01 day 21:00:00, uid=a, stime =1 day 00:00:00, count=30;
08 month 01 day 23:00:00, uid=a, stime =1 day 00:00:00, count=40;
From the above procedure, it can be seen that for 08 months 01 days 00:00:00-24:00: the balance of the changes occurring between 00, the cycle start times of which are Stime =1d00: 00:00, stone=1 day 00:00: the updating process of the balance value count of 00 is 18, 108, 100, 30 and 40 in sequence.
By analogy, for a balance change of 2 days, the process of updating the preset periodic balance table is as follows:
08 month 02 day 02:00:00, uid=a, stime =2 day 00:00:00, count=60;
08 month 02 day 10:00:00, uid=a, stime =2 day 00:00:00, count=80;
08 month 02 day 21:00:00, uid=a, stime =2 day 00:00:00, count=101;
I.e. Stime = 2 days 00:00: the updating process of the balance value count of 00 is 60, 80 and 101 in sequence.
Similarly, there was no change in balance on day 08, 03, uid=a, stime =3k00: 00:00, count=101;
08 month 04 day 10:00:00, uid=a, stime =4 day 00:00:00, count=10.
The final preset periodic balance at 08 month 04 day 10:00:00 is as follows:
| Uid | Stime | Count |
| A | 1 day 00:00:00 | 40 |
| A | 2 Days 00:00:00 | 101 |
| A | 3 Days 00:00:00 | 101 |
| A | 4 Days 00:00:00 | 10 |
As can be seen from the above example, when the balance of the account a is changed, that is, the balance value count of the corresponding period starting time Stime is updated, and the balance of the account a at 8 months 2 days 00:00:00 is to be obtained, the final balance of the account a before 8 months 2 days 00:00:00 is recorded by the balance balance=40 of the 8 months 1 days 00:00:00 in the preset period balance table, so the balance balance=40 of the 8 months 1 days 00:00:00 in the preset period balance table is the real instantaneous balance of the account a at 8 months 2 days 00:00:00. Therefore, the setting of the periodic balance table and the updating of the periodic balance table according to the balance change are realized, when the balance of the account at the designated period starting time is obtained, the balance value of the period starting time before the designated period starting time is used as the balance value of the account at the designated period starting time by searching the periodic balance table, the balance table is not required to be locked, other services related to the balance table are not influenced, the balance value of the corresponding period starting time in the periodic balance table is changed after the change of the balance of the account is monitored, the real instantaneous balance value of the account at the designated period starting time can be quickly obtained through the periodic balance table lookup table, all flowing water of the account is not required to be reserved to trace back to determine the balance value of the account through flowing water, the time and space complexity of the periodic balance table lookup operation are low, and the efficiency of obtaining the instantaneous balance is improved.
Example III
Fig. 3 is a step flow chart of a data processing method according to a third embodiment of the present invention, where the data processing method according to the first embodiment of the present invention is optimized based on the first embodiment, specifically, as shown in fig. 3, the data processing method according to the embodiment of the present invention may include the following steps:
S301, when the balance of the account is changed, obtaining the balance change time when the balance is changed and the balance value after the balance is changed.
In the implementation of the present invention, S301 may refer to S101 in the first embodiment, or S201 to S202 in the second embodiment, which are not described in detail herein for avoiding repetition.
S302, determining the cycle starting time of the balance period to which the balance change time belongs.
S303, updating the balance value of the account at the period starting time in a preset period balance table into the balance value, wherein in the preset period balance table, when the account and the period starting time are used for acquiring the balance of the account at the specified period starting time, the balance value of the account at the period starting time before the specified period starting time is used as the balance value of the account at the specified period starting time.
In the implementation of the present invention, S302 to S303 may refer to S102 to S103 in the first embodiment, or S203 to S206 in the second embodiment, which are not described in detail herein for avoiding repetition.
S304, if the current time is the period starting time of the current balance period, and the balance of the account is not changed within the current balance period, taking the balance value of the period starting time of the previous balance period as the balance value of the period starting time of the current balance period.
In an alternative embodiment of the present invention, the current time is inserted in the period balance table as the period start time of the current balance period, and the balance value of the period start time of the previous balance period is used as the balance value of the period start time of the current balance period.
Specifically, the current time may refer to the current time of the system, if the current time is the period starting time of the current balance period, the current time may be inserted in the preset period balance table as the period starting time of the current balance period, if the balance of the account within the current balance period does not change, the balance value of the last balance period may be used as the balance value of the current balance period, for example, in the example provided in step S206 of the second embodiment, when the current time is 08 months 03 days 00:00:00, the period starting time Stime =3 days 00:00:00 is inserted in the preset period balance table, and if the balance of the account a does not change within 08 months 03 days, stime =2 days 00:00: count=101 of 00 as Stime =3daily 00:00:00 balance, i.e. new Stime =3daily 00 in the preset periodic balance table: 00:00, count=101, thereby avoiding account a at Stime =3 days 00:00:00 has no balance value, cannot acquire account a on 3 days 00:00: a balance of 00.
When the current time is the period starting time of the current balance period and the balance of the account in the current balance period is unchanged, the balance value of the period starting time of the previous balance period is used as the balance value of the period starting time of the current balance period, so that the problem that the balance value of the account in the balance period cannot be obtained due to the fact that the balance value of the account in the balance period is not available due to the fact that the balance of the account in the balance period is not available in a certain balance period can be avoided, the balance value of the account in the balance period is available in the period starting time of each balance period, and the balance value of the account in the period starting time of each balance period can be obtained.
S305, counting the number of periods contained in the preset period balance table.
In one example, the number of cycle start times of the accounts in the preset cycle balance table may be counted as the number of cycles.
And S306, when the cycle number is larger than a preset threshold value, clearing balance values of the first N balance cycles before the cycle starting time.
In one example, the preset threshold may be 2, i.e., the balance value of the last 2 balance periods is retained in the preset period balance table, and the balance values of the first N balance periods before the period start time are deleted, so that the balance value of the last 2 balance periods is always retained in the preset period balance table. Assuming that the number of accounts is n, and data of the two latest balance periods are stored, the time complexity of table lookup is O (n log (n)), the space complexity is O (2 n), and m running water of each user is inconsistent with the time of each running water relative to n users, so that the time and space complexity of obtaining balance values are further reduced, the balance of the account at the starting time of a designated period can be obtained rapidly by querying a preset period balance table, and the efficiency of obtaining the balance of the account is improved.
It should be noted that, steps S304-S306 may be performed after S206 in the second embodiment as an optional step, and of course, steps S304-S306 may also be performed before or simultaneously with any one of the steps in the first embodiment, the second embodiment, or the third embodiment, which is not a limitation on when steps S304-S306 are performed in the present invention.
When the balance of the account is changed, the balance change time when the balance is changed and the balance value after the balance change are obtained, and after the period starting time of the balance period to which the balance change time belongs is determined, the balance value of the account in the preset period balance table at the period starting time is updated to be the balance value. Therefore, when the balance of the account at the appointed period starting time is obtained, the balance value of the account at the period starting time before the appointed period starting time is used as the balance value of the account at the appointed period starting time by searching the period balance table, the balance table is not required to be locked, other services related to the balance table are not affected, the balance value of the corresponding period starting time in the period balance table is changed after the change of the balance of the account is monitored, the real instantaneous balance value of the account at the appointed period starting time can be quickly obtained through the table lookup of the period balance table, all running water of the account is not required to be reserved to determine the balance value of the account through the running water backtracking, the time and space complexity of the table lookup operation on the period balance table is low, and the efficiency of obtaining the instantaneous balance is improved.
Further, when the current time is the period starting time of the current balance period and the balance of the account in the current balance period is not changed, taking the balance value of the period starting time of the previous balance period as the balance value of the period starting time of the current balance period, the balance value of the account in the balance period can be prevented from being obtained due to the fact that the balance value of the account in the balance period is not obtained due to the fact that the balance value of the account is not changed in the balance period in a certain balance period, and the account has the balance value at the period starting time of each balance period.
Furthermore, the number of cycles contained in the preset cycle balance table is counted, and when the number of cycles is larger than a preset threshold value, the balance values of the first N balance cycles before the starting time of the cycle are emptied, so that the complexity of time and space of table lookup is further reduced, the balance of the account at the starting time of the appointed cycle can be quickly obtained by querying the cycle balance table, and the efficiency of obtaining the balance of the account is improved.
