Description

Technical Field

[0001] The present invention relates to the technical field of message matching, and in particular to a message matching method, device and equipment for point-to-point conditional subscription between a client and a message middleware. Background Art

[0002] The point-to-point message consumption model in the message middleware means that when multiple consumers consume the same queue, each message is consumed by only one consumer. Conditional subscription means that when consumers subscribe to a message queue from the middleware, they set conditions and selectively subscribe to specific messages. Point-to-point consumption and conditional subscription are common functions of message middleware. For example, the most widely used message middleware API (Application Programming Interface) interface JMS (Java Message Service) provides these functions.

[0003] While satisfying the requirement of distributing correct messages to consumers for point-to-point conditional subscription, the message middleware must also take into account the balance of message distribution between consumers with different subscription conditions and between consumers with the same subscription conditions, and the efficiency of the distribution algorithm in time and space.

[0004] In order to realize the above requirements of point-to-point conditional subscription, the following difficulties need to be overcome:

[0005] 1. Regardless of whether the message is persistent or non-persistent, the message middleware must quickly match the message characteristics with the consumer's subscription conditions. If all messages are loaded into memory, the memory demand will be very huge. If only some messages are loaded into memory, the messages cannot be matched correctly.

[0006] 2. When the message middleware distributes messages to consumers, it must match each message with the subscription conditions of each consumer. Message matching is a computationally intensive operation, and the message middleware must minimize the number of message matches. For example, for multiple consumers with the same subscription conditions, only one match is required to exclude the possibility of distribution to such consumers.

[0007] 3. When a number of messages match the subscription conditions of multiple consumers, how to ensure that these messages can be evenly distributed to consumers that meet the conditions, so as to avoid some consumers consuming a large number of messages while other consumers consume a small number or no messages. Summary of the invention

[0008] The present invention provides a message matching method, device and equipment for point-to-point conditional subscription between a client and a message middleware, which is used to solve the defects in the prior art that if all messages are loaded into the memory, the memory demand consumption is very huge, if part of the messages are loaded into the memory, the messages cannot be correctly matched, and the messages that meet the same subscription conditions cannot be relatively evenly distributed to consumers.

[0051] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the drawings of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0052] The terms "first", "second", etc. in the present invention are used to distinguish similar objects, rather than to describe a specific order or precedence. It should be understood that the terms used in this way can be interchangeable where appropriate, so that the embodiments of the present application can be implemented in an order other than those illustrated or described herein, and the objects distinguished by "first", "second", etc. are generally of the same type.

[0053] The present invention provides a message matching method for point-to-point conditional subscription between a client and a message middleware. Figure 1 : is a flow chart of a message matching method for point-to-point conditional subscription between a client and a message middleware provided by the present invention, such as Figure 1 As shown, the method is applied to message middleware, and the method includes step 110, step 120 and step 130.

[0054] Step 110, obtaining an unconsumed queue of the server; the unconsumed queue is obtained by storing the to-be-matched messages in the form of message IDs.

[0055] Step 120, based on the maximum number of matching messages and the matching progress of each conditional subscription group, match each conditional subscription group with the characteristics of the messages to be matched in the unconsumed queue in the message matching order to obtain each successfully matched target message, and remove each target message from the unconsumed queue; each conditional subscription group is a subscription group composed of member consumers with the same subscription conditions.

[0056] Step 130: In response to the distribution operation of the server, distribute the target messages to the member consumers in the conditional subscription groups.

[0057] Specifically, the message middleware can obtain the unconsumed queue of the server, where the unconsumed queue is obtained by storing the to-be-matched message in the form of a message ID. In addition, in order to quickly match messages with conditional subscriptions, the embodiment of the present invention extracts message features from the complete message and caches them in memory with the message ID index.

[0058] Then, based on the maximum number of matching messages and the matching progress of each conditional subscription group, each conditional subscription group is matched with the features of the messages to be matched in the unconsumed queue in the message matching order to obtain each successfully matched target message, and each target message is removed from the unconsumed queue.

[0059] The maximum number of matching messages refers to the maximum matching length of the features of each conditional subscription group and the messages to be matched in the unconsumed queue, which may be 4 or 5, etc., and is not specifically limited in the embodiment of the present invention.

[0060] The matching progress refers to the matching index of each conditional subscription group in the unconsumed queue, which can be a g1 cursor, a g2 cursor, a g3 cursor, etc.

[0061] Here, each conditional subscription group is a subscription group composed of member consumers with the same subscription condition. Among them, the subscription condition can be "length is greater than 10", then the conditional subscription group is a subscription group composed of all member consumers that meet the subscription condition of "length is greater than 10". Member consumers refer to each member in the conditional subscription group.

[0062] Here, the features of the messages to be matched in the unconsumed queue are message features, which may be "the length of the box is XX meters", "the width of the box is XX meters", or "the height of the box is XX meters", etc. The embodiment of the present invention does not specifically limit this.

[0063] It is understandable that as messages are continuously generated, the memory usage of the message feature cache increases. The embodiment of the present invention uses a timer to periodically remove the features of consumed messages from the cache to release memory usage.

[0064] It can be understood that, based on the maximum number of matching messages and the matching progress of each conditional subscription group, each conditional subscription group is matched with the features of the messages to be matched in the unconsumed queue in the message matching order to obtain each successfully matched target message, and each target message is removed from the unconsumed queue. If the remaining messages in the unconsumed queue are not empty, it is necessary to update the message matching order, and record the matching progress of each conditional subscription group in the last execution of message matching. With the updated message matching order and the matching progress of each conditional subscription group, each conditional subscription group is matched with the features of the messages to be matched in the unconsumed queue until the remaining messages in the unconsumed queue are empty.

[0065] It should be noted that each conditional subscription group needs to save the matched target messages for subsequent average distribution to member consumers.

[0066] Finally, in response to the distribution operation of the server, each target message is distributed to each member consumer in each conditional subscription group. Here, each target message can be evenly distributed to each member consumer in each conditional subscription group. For example, the conditional subscription group matches 3 target messages, and the conditional subscription group has 3 member consumers, then the 3 target messages are evenly distributed to the 3 member consumers of the conditional subscription group, that is, one member consumer corresponds to one target message. For another example, the conditional subscription group matches 5 target messages, and the conditional subscription group has 3 member consumers, then the 5 target messages are evenly distributed to the 3 member consumers of the conditional subscription group, that is, the first two member consumers correspond to two target messages, and the last member consumer corresponds to one target message, which means that balanced distribution of messages is achieved.

[0067] It should be noted that 1) the matching calculation is performed on the basis of conditional subscription groups, and multiple consumers with the same subscription conditions and messages only have one matching calculation. 2) The message middleware organizes the unconsumed messages (which can be the message itself or the message ID) into an unconsumed queue, and all conditional subscription groups try to match the messages in the unconsumed queue in turn. 3) To ensure that each conditional subscription group has a fair chance to match messages, each conditional subscription group can only match a certain number of messages from the unconsumed queue at a time, to prevent a large number of messages from being consumed by one conditional subscription group when they meet multiple conditions.

[0068] The method provided by the embodiment of the present invention, on the one hand, compared with some message middleware that relies on full cache of messages, when the message cache is too large, it makes it impossible to match message features with subscription conditions. The method provided by the embodiment of the present invention, on the one hand, accurately indexes and caches message features according to the matching progress, and uses less memory; on the other hand, when there are multiple subscriptions with the same subscription conditions, after the conditional subscriptions are grouped, the message features are matched with each subscription condition only once, and the number of matches is greatly reduced. Furthermore, balanced distribution of messages can be guaranteed between member consumers with different subscription conditions and the same subscription conditions.

[0069] Based on the above embodiment, step 120 includes:

[0070] The first cycle is executed until the first preset condition is met:

[0071] The first cycle process includes:

[0072] Based on the maximum number of matching messages and the matching progress of each conditional subscription group, each conditional subscription group is matched with the features of the to-be-matched messages in the unconsumed queue in a message matching order to obtain each successfully matched target message, and each target message is removed from the unconsumed queue to obtain the target remaining messages;

[0073] The matching progress of each conditional subscription group is updated; the first preset condition is that the target remaining message is empty.

[0074] Specifically, Figure 2 is one of the schematic diagrams of the conditional subscription group matching message provided by the present invention, Figure 3 This is the second schematic diagram of the conditional subscription group matching message provided by the present invention. Figure 4 This is the third schematic diagram of the conditional subscription group matching message provided by the present invention. Figure 5 This is a fourth schematic diagram of a conditional subscription group matching message provided by the present invention, such as Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the first cycle process is executed until the first preset condition is met:

[0075] The first cycle process includes:

[0076] Based on the maximum number of matching messages and the matching progress of each conditional subscription group, each conditional subscription group is matched with the features of the to-be-matched messages in the unconsumed queue in the message matching order to obtain each successfully matched target message, and each target message is removed from the unconsumed queue to obtain the target remaining message. Here, the first preset condition is that the target remaining message is empty.

[0077] For example, the conditional subscription groups are g1, g2, and g3, and the message IDs of the unconsumed queue are 1, 2, 3, 4, 5, 6, 7, 8, 9, and 10. Among them, the conditional subscription group that can be satisfied by message ID1 in the unconsumed queue is g1, the conditional subscription group that can be satisfied by message ID3 in the unconsumed queue is g2, the conditional subscription groups that can be satisfied by message ID4 in the unconsumed queue are g1 and g3, the conditional subscription group that can be satisfied by message ID5 in the unconsumed queue is g2, the conditional subscription group that can be satisfied by message ID6 in the unconsumed queue is g1, the conditional subscription group that can be satisfied by message ID8 in the unconsumed queue is g3, and there is no conditional subscription group that can be satisfied by other messages in the unconsumed queue.

[0078] It should be noted that at the beginning, the matching progress of the conditional subscription groups g1, g2 and g3, that is, the cursors are all at the front of the unconsumed queue, and the maximum number of matching messages each time = 4.

[0079] The specific message matching process is as follows:

[0080] Based on the maximum number of matching messages and the matching progress of each conditional subscription group, the first conditional subscription group is matched with the features of the to-be-matched messages in the unconsumed queue to obtain the first target message that successfully matches, and the first target message is removed from the unconsumed queue to obtain the first remaining message;

[0081] Based on the maximum number of matching messages, the intermediate conditional subscription group is matched with the features of the first remaining message in sequence to obtain a second target message that successfully matches, and the second target message is removed from the first remaining message to obtain a second remaining message; the intermediate conditional subscription group is a conditional subscription group between the first conditional subscription group and the last conditional subscription group;

[0082] Based on the maximum number of matching messages, the last condition subscription group is matched with the second remaining message to obtain the last target message that matches successfully, and the last target message is removed from the second remaining message to obtain the target remaining message.

[0083] Here, three conditional subscription groups are used as an example. The message matching order starts with conditional subscription groups g1, g2, and g3. The first conditional subscription group is g1, the middle conditional subscription group is g2, and the last conditional subscription group is g3.

[0084] Then, a match is performed from the first conditional subscription group g1 to obtain the first target messages 1 and 4 that are successfully matched, and the first target messages 1 and 4 are removed from the unconsumed queue to obtain the first remaining messages 2, 3, 5, 6, 7, 8, 9 and 10.

[0085] After the first conditional subscription group g1 is matched, the intermediate conditional subscription group g2 is matched with the features of the first remaining message to obtain the second target messages 3 and 5 that are successfully matched, and the target messages 3 and 5 are removed from the first remaining message to obtain the second remaining messages 2, 6, 7, 8, 9 and 10.

[0086] If there are multiple intermediate condition subscription groups, the intermediate condition subscription groups are matched with the features of the first remaining message in sequence to obtain a successfully matched second target message, which will not be described in detail here.

[0087] After the matching of the middle condition subscription group g2 is completed, the last condition subscription group g3 is matched with the characteristics of the second remaining message to obtain the last target message 8 that successfully matches, and the last target message 8 is removed from the unconsumed queue to obtain the target remaining messages 2, 6, 7, 9 and 10.

[0088] Based on the above embodiment, based on the maximum number of matching messages and the matching progress of each conditional subscription group, each conditional subscription group is matched with the features of the to-be-matched messages in the unconsumed queue in a message matching order to obtain each successfully matched target message, and each target message is removed from the unconsumed queue to obtain the target remaining message, including:

[0089] The second cycle is executed until the second preset condition is met:

[0090] The second cycle process includes:

[0091] Updating the message matching order of each conditional subscription group;

[0092] Updating the matching progress of each conditional subscription group;

[0093] Based on the maximum number of matching messages and the matching progress of each conditional subscription group, each conditional subscription group is matched with the features of the to-be-matched messages in the unconsumed queue in the message matching order to obtain each successfully matched target message, and each target message is removed from the unconsumed queue to obtain the target remaining messages;

[0094] The second preset condition is that the message matching traversal of each conditional subscription group is completed.

[0095] Specifically, after the first round of message matching is completed, the message matching order of each conditional subscription group is updated, and the order of the first conditional subscription group in each conditional subscription group in the message matching order is moved to the end, and the order of the remaining conditional subscription groups in each conditional subscription group remains unchanged, that is, the matching order of each conditional subscription group is updated to g2, g3, and g1. That is, conditional subscription group g2 is used as the first conditional subscription group, conditional subscription group g3 is used as the middle conditional subscription group, and conditional subscription group g1 is used as the last conditional subscription group.

[0096] Update the matching progress of each conditional subscription group. Specifically, update the matching progress of conditional subscription group g1, that is, the g1 cursor points to 5 in the unconsumed queue, the matching progress of conditional subscription group g2, that is, the g2 cursor points to 7 in the unconsumed queue, and the matching progress of conditional subscription group g3, that is, the g3 cursor points to 9 in the unconsumed queue.

[0097] After updating the message matching order of each conditional subscription group and the matching progress of each conditional subscription group, each conditional subscription group can be matched with the features of the to-be-matched messages in the unconsumed queue according to the message matching order based on the maximum number of matching messages and the matching progress of each conditional subscription group to obtain each successfully matched target message, and each target message is removed from the unconsumed queue to obtain the target remaining messages;

[0098] The second preset condition is that the message matching traversal of each conditional subscription group is completed.

[0099] That is, conditional subscription group g2 is used as the first conditional subscription group, conditional subscription group g3 is used as the middle conditional subscription group, and conditional subscription group g1 is used as the last conditional subscription group, and the steps of matching the conditional subscription group with the features of the to-be-matched messages 2, 6, 7, 9, and 10 in the unconsumed queue are re-executed, which will not be repeated here. In addition, each conditional subscription group can also be 2 or 1, and the steps of matching the conditional subscription group with the features of the to-be-matched messages in the unconsumed queue in the message matching order are similar to the above description, which will not be repeated here.

[0100] It should be noted that, in addition, each subscriber can also be matched with each member consumer Consumer, but this method is less efficient.

[0101] It can be understood that the method provided by the embodiment of the present invention accurately caches message features in memory according to the matching progress; groups consumers subscribed to the same conditions to reduce the number of matches between messages and conditions; multiple conditional subscription groups are used to match messages, and after the conditional subscription group matches the message, it is evenly distributed to the member consumers in the group, thereby ensuring balanced distribution of messages between member consumers with different subscription conditions and the same subscription conditions.

[0102] The message matching device for point-to-point conditional subscription between a client and a message middleware provided by the present invention is described below. The message matching device for point-to-point conditional subscription between a client and a message middleware described below and the message matching method for point-to-point conditional subscription between a client and a message middleware described above can be referred to each other.

[0103] Based on any of the above embodiments, the present invention provides a message matching device for point-to-point conditional subscription between a client and a message middleware, Figure 6 It is a structural diagram of a message matching device for peer-to-peer conditional subscription between a client and a message middleware provided by the present invention, such as Figure 6 As shown, applied to message middleware, the device includes:

[0106] The distribution unit 630 is used to distribute the target messages to the member consumers in the conditional subscription groups in response to the distribution operation of the server.

[0107] The device provided by the embodiment of the present invention, on the one hand, compared with some message middleware that relies on the full cache of messages, when the message cache is too large, it makes it impossible to match the message characteristics with the subscription conditions. The method provides an accurate index cache of the message characteristics according to the matching progress, and uses less memory; on the other hand, when there are multiple subscriptions with the same subscription conditions, after the conditional subscriptions are grouped, the message characteristics are matched with each subscription condition only once, and the number of matches is greatly reduced. Furthermore, balanced distribution of messages can be guaranteed between member consumers with different subscription conditions and the same subscription conditions.

[0108] Based on any of the above embodiments, the message matching unit 620 is specifically configured to:

[0118] Based on the maximum number of matching messages and the matching progress of each conditional subscription group, each conditional subscription group is matched with the features of the to-be-matched messages in the unconsumed queue in the message matching order to obtain each successfully matched target message, and each target message is removed from the unconsumed queue to obtain the target remaining messages;

[0119] The second preset condition is that the message matching traversal of each conditional subscription group is completed.

[0120] Based on any of the above embodiments, the first cycle process is specifically used for:
