Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the invention and are not limiting of the invention. It should be further noted that, for the convenience of description, only some of the structures related to the present invention are shown in the drawings, not all of the structures. The embodiments and features of the embodiments in the present application may be combined with each other without conflict.
Example one
Fig. 1 is a flowchart of steps of a data processing method according to an embodiment of the present invention, where the method is applicable to a situation of counting an instantaneous balance of a user at a specified time point, and the method may be executed 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 is integrated in 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 a currency balance, or a virtual gold coin balance after the currency is exchanged into the virtual gold coin. For the balance of the account, when a user of the account consumes or charges the account, the balance of the account changes, and the system records the time when the balance changes and the changed balance value.
In a preferred embodiment, a balance table may be established for the account, where the balance table may be a table that records the balance change time and the changed balance value of the account, the balance is changed when a new record is added to the balance table, 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 applications, those skilled in the art may use different methods to obtain the balance change time and the balance value after the balance change according to the manner of recording the change of the balance when the balance changes.
And S102, determining the cycle starting time of the balance saving cycle to which the balance change time belongs.
In the embodiment of the present invention, the balance saving period may be a period of performing balance saving operation on the balance of the account, and the balance saving period may be in units of month, day, and hour, and may be, for example, 1 month, 1 day, or 1 hour.
The period starting time is the starting time of each balance period, or may be the deadline of the user for obtaining the account balance, in an example, the balance period is 1 month, when the balance of the account needs to be obtained at 00:00:00 every 1 day of the month, the period starting time is 00:00:00 every 1 day of the month, similarly, the balance period is 1 day, the period starting time is 00:00:00 every day, and the balance period is 1 hour, the period starting 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 saving cycle to which the balance change time when the balance is changed belongs can be determined. In one example, the balance cycle is 1 day, for example, for the balance cycle of 8/25/2020, when the balance of an account a changes at 07:15:23 on 8/25/2020, the cycle start time of the balance cycle to which 07:15:23 belongs on 8/25/2020 is 00:00:00 on 8/25/2020, and when the balance of an account a changes at 17:10:03 on 8/25/2020, the cycle start time of the balance cycle to which 17:10:03 belongs on 25/8/2020 is also 00:00: 00:00 on 8/25/2020.
In an optional embodiment of the present invention, the balance change time may be a balance change timestamp generated when the balance is changed, a time difference between a cycle start timestamp of a first balance period and 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, a sum of the product and the start timestamp of the first balance period is summed to obtain a cycle start time of the balance change timestamp, and the cycle start time is a cycle start time of the balance change period to which the balance change time belongs.
And 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 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.
Specifically, the period balance table may be a table in which accounts, period start time, and balance values are recorded, in an example, one period balance table may be generated for each account, and the period balance table records the balance values of the account at the period start time of each balance period, of course, one period balance table may also record the balance values of a plurality of accounts at the period start time of each balance period. After the cycle start time of the balance period to which the balance change time belongs is determined, the balance value can be replaced by the balance value corresponding to the cycle start time in the cycle balance table. Of course, if there is no balance value for the account at the start time of the cycle in the cycle balance table, the cycle start time and balance value may be inserted in the cycle balance table to obtain the balance value for the account at the start time of the cycle.
In practical applications, when the balance of the account at the specified period starting time needs to be acquired in response to the balance acquisition request, the balance of the account at the specified period starting time is updated, the balance of the account at the previous period starting time of the specified period starting time is taken as the balance acquisition result, the balance period is 1 day, and when the balance of the account a at 25/2020/25/00 (the specified period starting time) needs to be acquired, the balance of the account a at 00: 00/00 (the previous period starting time) at 24/2020/8/25/00/2020 in the period balance table can be taken as the balance of the account a at 25/00/2020/00.
In another example, when balance of all accounts at the starting time of the specified period needs to be acquired for balance operation, the balance values of all accounts at the starting time of the period before the starting time of the specified period in the period balance table are summed to obtain the balance value.
When the balance of the account is changed, the balance change time when the balance is changed and the balance value after the balance is changed are obtained, after the cycle start time of the balance cycle to which the balance change time belongs is determined, the balance value of the account in the preset cycle balance table at the cycle start time is updated to the balance value, so that when the balance of the account at the appointed cycle start time is obtained, the balance value of the account at the previous cycle start time of the appointed cycle start time is used as the balance value of the account at the appointed cycle start time by searching the cycle balance table, the balance table does not need to be locked, other services related to the balance table are not influenced, the balance value of the corresponding cycle start time in the cycle balance table is changed after the balance change of the account is monitored, the real instant balance value of the account at the appointed cycle start time can be quickly obtained by searching the cycle balance table, all running water of the account does not need to be reserved to determine the balance value of the account through running water backtracking, the time and space complexity of table look-up operation on the periodic balance table is low, and the efficiency of obtaining the instantaneous balance is improved.
Example two
Fig. 2 is a flowchart of steps of a data processing method according to a second embodiment of the present invention, where the embodiment of the present invention is optimized based on the first embodiment, specifically, as shown in fig. 2, the data processing method according to 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 consumption or recharging operation exists in an account, the balance of the account changes, and the balance of the account can be monitored in real time. Those skilled in the art may monitor the account balance in any manner to determine whether the account balance has changed, execute S202 when the account balance has changed, and otherwise continue to monitor the account balance.
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 changes, the system records the changed balance value and generates a time stamp, wherein the time stamp is the balance change time stamp which is the time when the balance changes. In one example, a running water is generated after the balance of the account is changed, and the running water at least comprises the changed balance value and a time stamp of the balance change when the balance is changed.
S203, calculating the cycle starting time of the balance saving cycle to which the balance change timestamp belongs by adopting the cycle starting timestamp of the first balance saving cycle, the balance change timestamp and the preset cycle duration.
In an optional embodiment of the present invention, the balance change time is a balance change timestamp generated when the balance is changed, a time difference from a cycle start timestamp of a first balance period 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 the cycle start time of the balance change timestamp is obtained by summing the product and a start timestamp of the first balance period.
Specifically, assume that the cycle start timestamp of the first balance cycle is S0If the cycle duration is T and the balance change timestamp is n, the cycle start time Stime of the balance change timestamp belonging to the balance save cycle can be calculated by the following formula:
Stime＝int((n-S0)/T)×T+S0
where int () is a floor function.
The process of calculating the cycle start time is illustrated below with a balance cycle of 1 day, assuming that user a is running at 08 months of 2020 as the following balance table:
| user ID | Time stamp for balance change | Balance value |
| A | 08 month and 01 day 09:30:01 in 2020 | 100 |
| A | Year 2020, 08 month, 01 day 19:00 | 50 |
| A | 08 month and 02 day 10:01:08 in 2020 | 70 |
| A | 20:07:08 at 03/2020/08/month | 80 |
| A | Year 2020, month 08, 03, 23:01:08 | 100 |
The cycle start timestamp S of the first balance cycle0When the preset period duration T is 24 hours, which is 08/01/00: 00:00 in 2020, the following steps are performed:
when the balance change time stamp n is 09:30:01, 08 month/01, 2020, it is compared with the cycle start time stamp S of the first balance period0The time difference (00: 00:00 of 01 d.08/01/2020) is 9.5 hours, the ratio of the time difference to the preset cycle time is 9.5/24, the ratio is rounded down by the number of cycles to be 0, and the cycle start time Stime of the balance saving cycle to which the balance change timestamp n belongs is 09:30:01 d.08/2020 is 00:00:00 of 01 d.08/2020;
when the balance change time stamp n is 19:00:00 on 08/01/2020, it is compared with the cycle start time stamp S of the first balance period0The time difference (01/00: 00/08/2020) is 19 hours, the ratio of the time difference to the preset cycle time is 19/24, the number of cycles is rounded down to 0, and the cycle start time Stime of the balance change timestamp n belonging to the balance saving cycle is 2020, 08/01/00;
when the balance change time stamp n is 08 months, 02 days 10:01:08 in 2020, it is compared with the cycle start time stamp S of the first balance period0(08/00) at 34 hours, the ratio of the time difference to the preset cycle duration is 34/24, the ratio is rounded down by 1, 1 × 24+ S cycles0The second balance period starting time after the first balance period starting time, namely the period starting time Stime of the balance period when the balance change timestamp n is 10:01:08 on 08/2020 and is 00:00:00 on 02/00: 00 on 08/2020;
by analogy, the balance change timestamp n is 20:07:08 on 03/08/2020, and the cycle start time Stime of the balance cycle is 00:00: 00:00 on 03/08/2020, and the balance change timestamp n is 23:01: 08/2020, 03/00: 00: 00/2020.
The balance period is in days, and can be 1 month, 1 week and the like in practical application, the period duration of the balance period is not limited by the embodiment of the invention, in addition, the technicians in the field can also set the cycle starting time of the balance period according to the actual requirement, if the starting time of the period is set to be 18:00:00 of each day, the balance saving period to which the balance change time stamp belongs can be directly determined through time logic, the cycle start time is determined by the associated balance cycle, which as in the above example is 20:07:08 on month 03 of 2020 as a balance cycle of 08 month 03 of 2020, the period start time is 03, 00 of 08-month-2020, and the period start time of the balance change time stamp is not limited in the embodiment of the present invention.
S204, judging whether the balance value of the account at the period starting time exists in the preset period balance table.
In an optional 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 an example, a table structure of the periodic balance table is as follows:
| name of field | Meaning of a field |
| Uid | User ID |
| Stime | Time of cycle start |
| Count | Balance |
During initialization, an account, the cycle start time of the first balance cycle, and the initial balance value may be written in the cycle balance table, in one example, the balance tables of all existing users may be pulled, and the account and the balance value in the balance tables may be imported into the preset cycle balance table to complete initialization. Inserting new cycle starting time and updating the balance value along with the lapse of time, judging whether the preset cycle balance table has the balance value of the account at the determined cycle starting time or not after the balance is changed and the cycle starting time of the balance cycle to which the balance change timestamp belongs is determined, if so, executing S205, and if not, executing S206.
S205, updating the balance value of the account at the period starting time in the preset period balance table to the balance value.
And for the period starting time of the balance period to which the balance change timestamp 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 currently monitored changed balance value.
S206, inserting the balance value into the preset period balance table to serve as the balance value of the account at the period starting time.
And for the cycle starting time of the balance cycle to which the balance change timestamp belongs, if the balance value of the account at the cycle starting time does not exist in the preset cycle balance table, inserting the cycle starting time into the preset cycle balance table, and setting the balance value of the inserted cycle starting time as the monitored changed balance value.
In order to make the embodiment of the present invention more clearly understood, the following describes the updating process of the balance 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 of each day, and the part of user a runs as follows (balance change):
the balance of 01:00:00 in 01/08 is 18 yuan in 2020;
the balance of 07:00:00 at 01/08/2020 is 108 yuan;
the balance of 12:00:00 at 01/08/2020 is 100 Yuan;
the balance of 21:00:00 at 01/08/2020 is 30 Yuan;
the balance of 23:00:00 on 01/08/2020 is 40 Yuan;
the balance of 02:00:00 of 08 and 02 of 2020 is 60 yuan,
The balance of 10:00:00 at 02/08 in 2020 is 80 yuan,
The balance of 21:00:00 on month 02 of 08 in 2020 is 101 yuan,
the balance is unchanged at 03 month 08 in 2020;
the balance of the account at 04: 00:00 is 10 yuan in 2020, 08 and 04 months.
The process of updating the preset periodic balance table is as follows:
day 01:00:00 on month 08, Uid ═ a, time ═ 1 day 00:00:00, count 18;
08/month 01, 07:00:00, Uid ═ a, Stime ═ 1 day 00:00:00, count 108;

21:00:00 on month 08, Uid ═ a, Stime ═ 1, day 00:00:00, count is 30;
23:00:00 on month 08, Uid ═ a, Stime ═ 1, day 00:00:00, count 40;
from the above process, for 08 months, day 01, 00:00: 00:00-24: 00:00, with a period start time of 1 day 00:00:00, 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 the balance change of 2 days, the process of updating the preset periodic balance table is as follows:
02/08/00, Uid ═ a, Stime ═ 2/00: 00:00, count 60;
10:00:00 on month 08, Uid ═ a, Stime ═ 2, day 00:00:00, count 80;
21:00:00 on month 08, Uid ═ a, Stime ═ 2, day 00:00:00, count 101;
i.e., time 00 on 2 days: 00: the updating process of the balance value count of 00 is 60, 80 and 101 in sequence.
Similarly, the balance on day 03 on month 08 was unchanged, Uid is a, time is 3 day 00:00:00, count 101;
08 month 04, 10:00:00, Uid ═ a, Stime ═ 4, 00:00:00, count 10.
The final preset periodic balance table at 04 days 08 month 10:00:00 is as follows:
| Uid | Stime | Count |
| A | 1 day 00:00 | 40 |
| A | 2 day 00:00 | 101 |
| A | 3 days 00:00 | 101 |
| A | 4 days 00:00 | 10 |
As can be seen from the above example, when the balance of the account a changes, that is, the balance count of the corresponding cycle start time Stime is updated, and when the balance of the account a is to be obtained on 2 days 00:00:00 in 8 months, since the balance count of 00:00:00 in 1 day 00 in 8 months is 40 of the last balance of the account a before 00:00:00 in 2 days 00:00 in 8 months in the preset cycle balance table, 40 of the balance count of 00:00:00 in 1 day 00 in 8 months in the preset cycle balance table is the real instantaneous balance of the account a on 2 days 00:00:00 in 8 months. Therefore, the periodic balance table is set and updated according to the balance change, when the balance of the account at the starting time of the appointed period is obtained, the balance value of the starting time of the period before the starting time of the designated period is used as the balance value of the account at the starting time of the designated period by searching the period balance table, the balance table does not need to be locked, other services related to the balance table are not influenced, and the balance value of the balance table of the period corresponding to the period starting time is changed after the balance of the account is monitored to be changed, the real instant balance value of the account at the appointed period starting time can be quickly obtained through the table look-up 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 look-up operation of the periodic balance table is low, and the efficiency of obtaining the instantaneous balance is improved.

Fig. 3 is a flowchart of steps of a data processing method according to a third embodiment of the present invention, where the first embodiment of the present invention is optimized, and specifically, as shown in fig. 3, the data processing method according to the third 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 practice of the present invention, S301 can refer to S101 in the first embodiment, or refer to S201-S202 in the second embodiment, and will not be described in detail herein to avoid repetition.
S302, determining the cycle starting time of the balance saving cycle to which the balance change time belongs.
And S303, updating the balance value of the account at the period starting time in a preset period balance table to 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 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 the practice of the present invention, reference is made to S102-S103 in the first embodiment or S203-S206 in the second embodiment, and the detailed description thereof is omitted here for the sake of avoiding redundancy.
S304, if the current time is the cycle starting time of the current balance period, and when the balance of the account in the current balance period is not changed, taking the balance value of the cycle starting time of the last balance period as the balance value of the cycle starting time of the current balance period.
In an optional embodiment of the present invention, the current time is inserted into 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 a current time of the system, and if the current time is a cycle start time of the current balance cycle, the current time may be inserted into the preset cycle balance table as the cycle start time of the current balance cycle, and if no change occurs in the balance of the account within the current balance cycle, the balance value of the previous balance cycle may be used as the balance value of the current balance cycle, for example, in the example provided in step S206 of embodiment two, when the current time is 08 month 03 day 00:00:00, the cycle start time Stime is inserted into the preset cycle balance table as 3 day 00:00:00, and if the balance of the account a is unchanged within 08 month 03 day, the period start time is 2 day 00:00: the sum of 00 is 101 as the balance value of 3 days 00:00:00, namely, the new added balance of the preset periodic balance table is 3 days 00:00:00, count 101, thereby avoiding account a being rated on a time of 1 on Stime 3 day 00:00:00 has no balance, account A can not be acquired in 3 days 00:00: 00.
When the current time is the cycle starting time of the current balance cycle and the balance of the account in the current balance cycle is not changed, the balance value of the cycle starting time of the last balance cycle is used as the balance value of the cycle starting time of the current balance cycle, so that the problem that the balance value of the account in the balance cycle cannot be acquired due to the fact that the account in a certain balance cycle has no balance change and cannot be acquired due to the fact that the account in the balance cycle is not changed can be solved, the account has the balance value at the cycle starting time of each balance cycle, and the balance value of the account in each cycle starting time can be acquired.
S305, counting the number of cycles contained in the preset cycle balance table.
In one example, the number of cycle start times of the account in the preset cycle balance table may be counted as the number of cycles.
And S306, clearing the balance.
In one example, the preset threshold may be 2, that is, the balance value of the last 2 balance cycles is retained in the preset cycle balance table, and the balance value of the first N balance cycles before the start time of the cycle is deleted, so that the balance value of the last 2 balance cycles is always retained in the preset cycle balance table. Assuming that the number of the accounts is n, storing data of the last two balance periods, the time complexity of table lookup is O (n × log (n)), the space complexity is O (2n), and compared with n users, the number of running water of each user is m, and the time of each running water is inconsistent, so that the time and space complexity of acquiring the balance value is further reduced, the balance of the account at the starting time of the designated period can be quickly acquired by inquiring a preset period balance table, and the efficiency of acquiring the balance of the account is improved.
It should be noted that steps S304-S306 may be optional execution steps after S206 in the second embodiment, and of course, steps S304-S306 may also be executed before or simultaneously with any one of the steps in the first embodiment, the second embodiment, or the third embodiment, and the implementation of the present invention does not limit when steps S304-S306 are executed.
When the balance of the account is changed, the balance change time when the balance is changed and the balance value after the balance is changed are obtained, and after the cycle start time of the balance cycle to which the balance change time belongs is determined, the balance value of the account at the cycle start time in the preset cycle balance table is updated to the balance value. Therefore, when the balance of the account at the appointed period starting time is obtained, the balance value at the previous period starting time of the appointed period starting time is used as the balance value of the account at the appointed period starting time through the search period balance table, the table locking of the balance table is not needed, other services related to the balance table are not affected, the balance value of the balance table at the corresponding period starting time is changed after the balance of the account is monitored, the real instant balance value of the account at the appointed period starting time can be quickly obtained through the period balance table look-up, all running water of the account is not needed to be reserved to determine the balance value of the account through the running water backtracking, the time and space complexity of the table look-up operation of the period balance table are low, and the efficiency of obtaining the instant balance is improved.
Further, when the current time is the cycle start time of the current balance cycle and the balance of the account in the current balance cycle is not changed, the balance value at the cycle start time of the last balance cycle is used as the balance value at the cycle start time of the current balance cycle, so that the problem that the balance value of the account in the balance cycle cannot be acquired due to the fact that the account in a certain balance cycle has no balance change can be avoided, and the account has the balance value at the cycle start time of each balance cycle.
Furthermore, the number of cycles contained in the preset cycle balance table is counted, and when the number of cycles is greater than the preset threshold, balance values of the first N balance cycles before the cycle starting time are cleared, so that the time and space complexity of table lookup is further reduced, the balance of the account at the starting time of the specified cycle can be quickly obtained by inquiring the cycle balance table, and the efficiency of obtaining the account balance is improved.
