Detailed Description

Exemplary embodiments of the present invention are described below with reference to the accompanying drawings, in which various details of embodiments of the invention are included to assist understanding, and which are to be considered as merely exemplary. Accordingly, those of ordinary skill in the art will recognize that various changes and modifications of the embodiments described herein can be made without departing from the scope and spirit of the invention. Also, descriptions of well-known functions and constructions are omitted in the following description for clarity and conciseness.

The ID may be used to identify unique information for subsequent queries, such as order numbers in an order system, may be used to query logistics information, merchandise information, and the like. The invention aims to obtain distributed high-concurrency, continuous self-increment and infinite IDs (identity) in a distributed mode, wherein:

1) self-INCREMENT (AUTO _ INCREAENT), the other meaning is that the ID is ordered, and the order number is taken as an example, so that the order quantity within a certain time can be calculated conveniently;

2) the method can obtain more IDs infinitely, the condition of ID recycling is not easy to occur, and the method does not recycle the IDs within the data range.

Referring to fig. 1, a main flowchart of an identifier management method according to an embodiment of the present invention is shown, including the following steps:

s101: receiving an identification obtaining request, and obtaining and feeding back an identification from a standby number section if the residual quantity of the current identification in the main number section is less than or equal to a first numerical value;

s102: in the process of feeding back the identifier, if the residual amount of the identifier in the standby number segment is judged to be less than or equal to a second numerical value, the loading operation of the identifier in the main number segment is triggered, so that the identifier is extracted from a database and is stored in the main number segment.

In the above embodiment, for step S101, in order to prevent time consumption caused by reading and updating the database from affecting the response speed of the service, the present invention provides an ID acquisition service by using a number segment on the basis of the database; where a number segment is a generic name for a set of spare IDs cached in a cache library (e.g., Redis).

In addition to the main number segment, the invention is also provided with a spare number segment, the IDs stored in the two segments are different, and the initial value/the end value of the IDs are adjacent, for example, the IDs in the main number segment are 1-1001, the IDs in the spare number segment are 1002-2002, then the IDs in the main number segment in the next stage are 2003-3003, and so on.

By adopting the main/standby mode, when an ID acquisition request is received, whether the request can be processed in the main number section is judged firstly, and if not, the standby number section is switched to be processed.

The number segment is mainly used for storing the ID, so that the basis for judging whether the main number segment can process the request is to judge whether the ID is stored in the main number segment:

1) if yes, extracting one ID and feeding back:

the IDs in the No. 1 section are continuous and self-increment, so that the ID of the first current sequence can be extracted according to the ID sequence mode, such as 1;

secondly, one ID can be randomly selected because the IDs in the number segments are different;

2) if not, namely the ID in the main number segment is completely consumed, the processing is switched to the standby number segment.

In the above manner, it is determined whether the ID in the main number segment is completely consumed (i.e. the first value is 0), in actual operation, the first value may also be set to other values, such as 1, 2, etc., but in order to avoid the situation that the number is too large because the ID in the number segment is not completely consumed, i.e. a new ID is loaded, the first value is usually set to 0.

In addition, when the main number section is in an abnormal state, no matter whether the ID is consumed or not, the main number section is switched to the standby number section for processing so as to extract and feed back one ID in sequence or at random.

For step S102, in order to adapt to the high concurrency condition, when the remaining amount of the ID in the number segment is small, the present invention can trigger another number segment to load the ID, so that when there is no ID in one of the number segments, the present invention can directly switch to another number segment to continue processing the ID acquisition request, thereby ensuring the uninterrupted operation of ID acquisition.

Taking the main number segment as an example, when the remaining amount of the ID is less than or equal to a third value (e.g., 400), the loading operation of the ID in the spare number segment is triggered; and for the spare number segment, when the remaining quantity of the ID is less than or equal to a second value (for example, 300, 400, which may be equal to a third value, or may not be equal to the third value), the loading operation on the ID in the main number segment is triggered.

In addition, the loading of the ID in the spare number segment is asynchronous loading, so that the congestion degree of the obtained ID is reduced, and the influence on an ID generation system is avoided.

Similarly, in the process of processing the ID acquisition request by using the spare number segment, if the remaining ID is less than or equal to the fourth value (less than the second value, usually 0), the process is directly switched to the primary number segment process. By loading and using the ID of the main and standby number segments in turn, the high efficiency and the continuity of ID acquisition are ensured.

The method provided by the above embodiment adopts the active/standby mode, and when the remaining amount of the ID in one of the number segments is small, the other number segment is triggered to load the ID, so as to ensure that the number segment is directly switched to the other number segment for processing when no ID is available, and through the manner of loading and using the ID by the active/standby number segments in turn, the dependency on the database is reduced, and the high efficiency and the continuity of ID acquisition are ensured.

Referring to fig. 2, a schematic flow chart of an optional identifier management method according to an embodiment of the present invention is shown, including the following steps:

s201: responding to the starting operation of the identification generation system, and acquiring a starting value of the identification in the current database; wherein the identities in the database are continuous and self-increasing;

s202: counting a first consumption identified in a main number section within a preset historical time length, and taking a quotient of the first consumption and the preset historical time length as the consumption rate;

s203: determining the consumption of the mark within a preset time according to the consumption rate of the mark in the main number section, and taking the sum of the initial value and the consumption as an ending value of the mark;

s204: and extracting the identifiers in the interval of the starting value and the ending value from the database and storing the identifiers in the main number segment.

In the above embodiment, for steps S201 to S203, when the ID generation system is started, the primary number segment in the number segment update module needs to initialize one segment of ID to provide the ID obtaining service, specifically:

1) querying a database (e.g., Mysql database), determining a starting value for the ID in the database, e.g., a starting value of 1;

2) the consumption rate of the IDs in the main number segment is estimated/calculated to calculate the amount of IDs that need to be consumed within a predetermined time period (or step size). For example, 100 IDs are consumed in 1 minute, and assuming that the main number segment needs to provide ID acquisition service for 10 minutes, the ID consumption amount calculated is 1000;

in addition, the ID consumption rate may be estimated according to specific traffic volume, or may be calculated according to historical data, for example, the order placing amount per minute in the order system is 200, and the consumption rate of the ID (i.e. order number) is 200 per minute.

3) Calculating the sum of the initial value and the calculated ID amount to obtain an end value;

4) and acquiring the calculated ID quantity from the database from the initial value, or extracting the ID between the initial value and the final value, and then storing the ID into the main number segment to finish the initialization operation of the main number segment ID, such as 1-1001.

Note that the ID start value in the database is updated as the ID is extracted, and for example, the start value is 1 before the ID is extracted from the major number segment, and is changed to 1002 after the extraction, indicating the ID loading cutoff position.

The above operation of loading the ID from the database is the same for the spare number segment, but the ID start value (i.e. the first start value) is located after the end value of the main number segment and adjacent to the end value, as in 1002, the spare number segment starts from 1002 when the ID is extracted.

In addition, the ID consumption rate in the spare number segment may be different from that of the main number segment, for example, the ID consumption rate in the main number segment is 100 per minute, and the spare number segment is 150 per minute, or may be set to the same consumption rate.

Similarly, the duration (i.e. the first predetermined duration) for providing the ID obtaining service by the spare number segment may also be different from the main number segment, for example, 10 minutes in the main number segment, and 8 minutes in the spare number segment, or may both be set to the same duration.

Taking the same consumption rate and the same time length as an example, the ID acquired by the primary number segment is 1-1001, and the ID acquired by the standby number segment is 1002-2002.

The method provided by the above embodiment fully considers the consumption rate of the number segment for the ID, so as to dynamically calculate the termination value of the ID in the number segment according to the consumption rate, thereby facilitating ID management and tracing.

Referring to fig. 3, a flowchart of a specific identifier management method according to an embodiment of the present invention is shown, including the following steps:

s301: responding to the starting operation of the ID generation system, and acquiring the initial value of the ID in the current database; wherein the IDs in the database are continuous and self-increasing;

s302: determining the consumption of the ID in a preset time period according to the consumption rate of the ID in the main number section, and taking the sum of the initial value and the consumption as the termination value of the ID;

s303: extracting IDs within the interval of the starting value and the ending value from a database and storing the IDs in a main number section;

s304: receiving an ID acquisition request, and judging whether the main number section is abnormal or not;

s305: if yes, switching to a standby number section to process the ID acquisition request;

s306: if not, judging whether the residual quantity of the current ID in the main number section is empty, if so, turning to the step S305;

s307: if not, extracting an ID from the residual IDs and feeding back, and judging whether the residual quantity is less than or equal to a third numerical value; wherein the third value is greater than 0;

s308: if yes, triggering loading operation of the ID in the spare number section;

s309: acquiring a first initial value of a current ID of a database; wherein the first start value is located after and adjacent to the end value;

s310: acquiring second consumption of the ID within a first preset time according to the consumption rate of the ID in the spare number segment, and taking the sum of the first initial value and the second consumption as a first termination value of the ID;

s311: extracting IDs positioned in a first starting value interval and a first ending value interval from a database and storing the IDs into a spare number segment;

s312: judging whether the residual quantity of the ID in the standby number section is less than or equal to a second numerical value or not in the process of feeding back the ID by the standby number section; wherein the second value is greater than 0;

s313: if yes, triggering the loading operation of the ID in the main number section;

s314: if not, the rest ID acquisition requests are continuously processed, and when the residual quantity of the IDs in the standby number section is 0, the ID acquisition requests are processed by switching to the main number section.

Compared with the prior art, the method provided by the embodiment of the invention has at least the following beneficial effects:

1) setting a number segment as a cache library of the ID in the database, and when receiving an ID acquisition request, firstly processing the request by using the number segment so as to reduce the dependency on the database;

2) even if the database is abnormal, the main and standby number sections can provide ID acquisition service for a period of time, so that the high availability of the whole system is ensured, and precious time is strived for system recovery;

3) in the numerical range allowed by the database, the obtained ID is infinite, and the phenomenon of repeated recycling caused by the exhausted ID is not considered;

4) only when the residual quantity of the IDs in the number segments is small, the IDs are triggered to be extracted from the database, so that the connection quantity between the IDs and the database is greatly reduced, and the database is not easy to crash and crash even if high concurrency conditions occur;

5) fully considering the consumption rate of the ID in the number segment, and realizing the dynamic management of the ID in the number segment, wherein the ID quantity stored in the number segment corresponds to the consumption rate;

6) and performing strong consistency synchronization by adopting a main/standby mode. When the residual quantity of the ID in one number section is small, the other number section is triggered to load the ID, the number section is directly switched to the other number section for processing when no ID is available, the dependency on a database is reduced through the mode that the ID is loaded and used by the main number section and the standby number section in turn, and the high efficiency and the continuity of the ID acquisition are ensured.

Referring to fig. 4, a frame diagram 400 of an identifier management method according to an embodiment of the present invention is shown, which includes the following units:

1. an acquisition ID unit: and acquiring the ID by inquiring the Redis number segment updating unit according to the specific key.

Redis is a high-performance key-value database, the key value is customized when the ID is cached to the Redis, for example, "nextId", and each time the Redis number segment updating unit is called, the Redis needs to be queried by the nextId to obtain the ID.

2. Redis number segment update unit: redis has high read-write performance, and ensures that the system can efficiently acquire the ID. The minimum QPS of the Redis standalone can reach 5W +, so the method selects a mode of inquiring the Redis to acquire the ID to support high concurrency.

3. Database number segment initial value updating unit: it is an important guarantee that the system outputs continuously increasing IDs, and the initial value is updated adaptively after each ID extraction.

Referring to fig. 5, a schematic diagram of main modules of an identifier management apparatus 500 according to an embodiment of the present invention is shown, including:
