Detailed Description
The following description of the embodiments of the present invention will be made clearly and fully with reference to the accompanying drawings, in which it is evident that the embodiments described are some, but not all embodiments of the invention. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
For ease of understanding, some of the following descriptions are directed to embodiments of the present invention:
load balancing (Load Balance): it is understood that the execution is split over multiple operating units, such as Web servers, file transfer protocol (File Transfer Protocol, FTP) servers, enterprise critical application servers, and other critical task servers, etc., to collectively complete a job task.
A Producer node, also referred to as a message Producer node, belongs to the originator of the service and is responsible for producing messages for provision to consumer nodes.
Consumer (Consumer) node: the message consumer node can also be called a message consumer node, belongs to a processing party of a service and is responsible for acquiring a message from a producer node and carrying out service logic processing, wherein the consumer node can directly acquire the message from the producer node through a synchronous interface and can also acquire the message from the producer node through a message middleware.
Message middleware: message queues may also be referred to as platform-independent data communication using efficient and reliable messaging mechanisms, and integration of distributed systems based on data communication. By providing a messaging and message queue model, communications of processes can be extended in a distributed environment.
Input Output (IO) intensive: the CPU performance of the system is much better than that of the hard disk and the memory, at this time, most of the system is operated by the read/write operation of the CPU in the same I/O (hard disk/memory), at this time, the load (Loading) of the CPU is not high, and in most of the cases, for the distributed system, the IO generally refers to the overhead of the network IO.
Point-to-point interaction: also referred to as single-node interactions, i.e., one producer node interacts with only one consumer node, illustratively, as shown in fig. 1, the producer node sends a message to the consumer node, which processes the message and returns a feedback message. It can be appreciated that in the single-node interaction mode, there is no load balancing problem.
Interaction between clusters: i.e. interactions between a plurality of producer nodes and a plurality of consumer nodes, illustratively, as shown in fig. 2, each producer node in the producer cluster may interact with a plurality of consumers in the consumer cluster, the producer node sends a message to the consumer node, and the consumer node processes the message and returns a feedback message.
The embodiment of the invention provides a message processing method which is applied to a first producer node, wherein communication connection is established between the first producer node and at least two consumer nodes. Referring to fig. 3, fig. 3 is a flowchart of a message processing method according to an embodiment of the present invention, as shown in fig. 3, including the following steps:
In this embodiment, a communication connection is established between a first producer node and at least two consumer nodes, that is, each consumer node of the at least two consumer nodes may receive a message to be consumed sent by the first producer node, and as illustrated in fig. 4, each producer node may deliver the message to be consumed to a plurality of consumer nodes. Wherein the first producer node may be any producer node.
The at least one consumer node may comprise some or all of the at least two consumer nodes. In practical applications, the first consumer node may send the message to be consumed to all consumer nodes in one message delivery, or may send the message to be consumed to only some consumer nodes. Further, it will be appreciated that the messages to be consumed sent by the first consumer node to the different consumer nodes are different, and illustratively, the first consumer node sends message a to be consumed to consumer node a, the first consumer node sends message B to consumer node B, and so on.
For example, as shown in fig. 4, after each consumer node finishes processing the message to be consumed, a feedback message for the message to be consumed may be sent to the first producer node, where the feedback message carries pressure related information of the consumer node. For example, if the first consumer node sends the message a to be consumed to the consumer node a, after the consumer node a completes processing the message a to be consumed, a feedback message for the message a to be consumed may be sent to the first consumer node, where the feedback message carries information related to the pressure of the consumer node a; if the first consumer node sends the message B to be consumed to the consumer node B, the consumer node B may send a feedback message for the message B to be consumed to the first consumer node after completing the processing of the message B to be consumed, where the feedback message carries information about the pressure of the consumer node B, and so on.
The pressure related information of the consumer node is used for representing the load pressure condition of the consumer node, that is, the pressure related information of the consumer node can be used for knowing the load pressure condition of the consumer node, for example, the load pressure is higher or the load pressure is lower. Illustratively, the pressure related information of the consumer node may include, but is not limited to, at least one of a pressure index value, a pressure evaluation value, and the like. The pressure index value may include one or more of disk occupancy rate, CPU occupancy rate, memory occupancy rate, downstream call response time, disk writing speed, thread pool size, and the like. The pressure evaluation value may be calculated based on one or more pressure index values, for example, a pressure evaluation value may be calculated based on the CPU occupancy and the memory occupancy, and the pressure evaluation value may be fed back to the producer node.
In some alternative embodiments, the first producer node may store the pressure-related information of each of the at least one consumer node, for example, in a local cache or a shared cache, where the shared cache may also be referred to as a distributed cache, and may be readable and writable by a plurality of producer nodes, when the pressure-related information of each of the at least one consumer node is received.
And 303, carrying out load balancing according to the pressure related information of part or all of the at least two consumer nodes.
For the above step 303, the first producer node may load balance directly based on the received pressure-related information of each of the at least one consumer node, or the first producer node may read the pressure-related information of each of the at least two consumer nodes from a cache (e.g., a local cache or a shared cache, etc.), and load balance based on the read pressure-related information of each of the at least two consumer nodes. The load balancing is performed according to the pressure related information of the consumer node, and for example, some messages to be consumed are allocated to the consumer node with higher load pressure, and some messages to be consumed are allocated to the consumer node with lower load pressure.
According to the message processing method provided by the embodiment of the invention, a first producer node sends a message to be consumed to at least one consumer node in at least two consumer nodes; receiving feedback messages sent by each consumer node of the at least one consumer node for the message to be consumed respectively, wherein each feedback message carries pressure related information of the corresponding consumer node; and carrying out load balancing according to the pressure related information of part or all of the at least two consumer nodes, wherein the load balancing effect can be improved due to the fact that the first consumer node carries out load balancing according to the actual pressure condition of each message consumer node, and in addition, the pressure related information of the message consumer node is carried by each consumer node in a feedback message aiming at the message to be consumed, so that the network resource cost of pressure related information feedback can be reduced. It should be further noted that, because the consumer node directly transmits the pressure-related information to the producer node, that is, other than the consumer node and the producer node, there is no interaction with other devices, so that the time delay of reporting the pressure-related information of the consumer node can be reduced, the pressure-related information of the consumer node acquired by the producer node can be ensured to more accurately reflect the current pressure condition of the consumer node, and further the effect of load balancing based on the pressure-related information of the consumer node can be improved,
Optionally, a communication connection is established between each consumer node of the at least two consumer nodes and at least two producer nodes, and the first producer node is any producer node of the at least two producer nodes;
after the receiving feedback messages sent by each consumer node of the at least one consumer node for the message to be consumed, respectively, the method further comprises:
storing pressure related information of each consumer node of the at least one consumer node in a shared cache, wherein the shared cache supports sharing between the at least two producer nodes;
the load balancing according to the pressure related information of some or all consumer nodes in the at least two consumer nodes comprises:
acquiring pressure related information of each consumer node in the at least two consumer nodes from the shared cache at intervals of a first preset time length;
and carrying out load balancing according to the pressure related information of each consumer node in the at least two consumer nodes.
The first preset duration may be set reasonably according to practical situations, for example, 1 minute, 5 minutes, or 10 minutes. In some alternative embodiments, the first preset duration may be set according to a service type, for example, for a service with a larger message amount, the first preset duration may be set smaller, and for a service with a smaller message amount, the first preset duration may be set larger.
Illustratively, as shown in FIG. 5, each producer node stores the consumer node's pressure-related information in the shared cache upon receiving the consumer node's pressure-related information returned by the consumer node. In addition, each producer node may read the latest pressure related information of each consumer node from the shared cache at intervals of a first preset duration, and perform load balancing based on the latest pressure related information of each consumer node.
In this embodiment, each producer node may store the received pressure related information of the consumer node in the shared cache, so that the shared cache may store the latest pressure related information of each consumer node, and each producer node may further obtain the latest pressure related information of each consumer node based on the shared cache to perform load balancing, so that the effect of load balancing of each consumer node may be improved.
In some alternative embodiments, the method further comprises:
and under the condition that the message to be consumed is not sent to the first consumer node within the second preset time period, receiving the pressure related information of the first consumer node sent by the first consumer node, wherein the first consumer node is any consumer node in the at least two consumer nodes.
In this embodiment, the second preset duration may be set reasonably according to practical situations, for example, 15 minutes, 30 minutes, 1 hour, etc.
In this embodiment, the consumer node may actively feed back the pressure related information of the message to be consumed to the producer node when the message to be consumed is not received for a longer period of time, so that the producer node may update the stored pressure related information of the consumer node based on the pressure related information actively fed back by the consumer node, so that the producer node may perform load balancing based on the latest pressure related information of each consumer node, so as to improve the load balancing effect.
In some alternative embodiments, the pressure related information of the consumer node includes at least one of: the pressure index value and the pressure evaluation value of the consumer node;
Wherein the pressure evaluation value is determined according to a pressure index value of the consumer node.
In some alternative embodiments, the pressure index value may include, but is not limited to, at least one of: disk occupancy, CPU occupancy, memory occupancy, downstream call response time.
The pressure evaluation value may be directly used to evaluate the pressure of the consumer node, for example, the pressure evaluation value may be a pressure score value calculated according to at least one pressure index value, where the greater the pressure score value of the consumer node, the greater the load pressure of the consumer node, and the smaller the pressure score value of the consumer node, the smaller the load pressure of the consumer node.
In an embodiment, each consumer node may report at least one pressure index value, for example, a disk occupancy rate, a CPU occupancy rate, a memory occupancy rate, a downstream call response time, etc., to the producer node, so that the producer node may calculate a load balancing weight value or a load balancing score, etc., corresponding to each consumer node according to the at least one pressure index value reported by each consumer node, respectively, and may perform load balancing based on the load balancing weight value or the load balancing score, etc., corresponding to each consumer node. The method is beneficial to ensuring the consistency of the calculation modes of the load balancing weight values or the load balancing scores corresponding to the consumer nodes, and further improving the accuracy of load balancing.
In another embodiment, each consumer node may report the pressure evaluation value calculated based on at least one pressure index value to the producer node, so that the producer node may directly perform load balancing according to the pressure evaluation value of each consumer node, without performing additional calculation, so that not only the resource overhead of reporting the pressure related information by the consumer node may be reduced, but also the calculation resource of the producer node may be saved.
In some alternative embodiments, the load balancing according to the pressure related information of some or all consumer nodes of the at least two consumer nodes includes:
and carrying out load balancing according to the pressure related information of each consumer node in the at least two consumer nodes and the message response time corresponding to each consumer node, wherein the message response time is the time when the first producer node sends a message to be consumed to the first producer node receives a feedback message aiming at the message to be consumed.
In practical application, there may be a difference in network state between the producer node and each consumer node, and for a consumer node with a better network state, the message response time of the consumer node is often shorter, and at this time, the producer node often wants to send more messages to be consumed to the consumer node; for consumer nodes with poor network state, the message response time is longer, and the producer node wants to send fewer messages to be consumed to the consumer node, which is beneficial to improving the message pushing efficiency.
According to the embodiment, load balancing is performed by integrating the pressure related information and the message response time of each consumer node, for example, the producer node can perform weighted calculation on the pressure evaluation value and the message response time of the consumer node to obtain a load balancing score, and load balancing is performed based on the load balancing score, so that the load balancing effect among the consumer nodes can be ensured, and meanwhile, the message pushing efficiency is considered.
Fig. 6 is a flowchart of a message processing method according to another embodiment of the present invention, which is applied to a first consumer node, as shown in fig. 6, and includes the steps of:
In this embodiment, the first producer node may be any producer node, where a communication connection is established between the first producer node and at least two consumer nodes, that is, each of the at least two consumer nodes may receive a message to be consumed sent by the first producer node. The first consumer node may be any consumer node of the at least two consumer nodes.
The first consumer node may consume the message to be consumed may understand that the first consumer node performs related processing on the message to be consumed, for example, if the message to be consumed is an account query request message, the first consumer node may query related information of a corresponding account based on the account query request message.
The pressure related information of the consumer node is used for representing the load pressure condition of the consumer node, that is, the pressure related information of the consumer node can be used for knowing the load pressure condition of the consumer node, for example, the load pressure is higher or the load pressure is lower. Illustratively, the pressure related information of the consumer node may include, but is not limited to, at least one of a pressure index value, a pressure evaluation value, and the like. The pressure index value may include one or more of disk occupancy rate, CPU occupancy rate, memory occupancy rate, downstream call response time, disk writing speed, thread pool size, and the like. The pressure evaluation value may be calculated based on one or more pressure index values, for example, a pressure evaluation value may be calculated based on the CPU occupancy and the memory occupancy, and the pressure evaluation value may be fed back to the producer node.
For example, if the message to be consumed is an account query request message, the feedback message of the message to be consumed may include information about the corresponding account, and in addition, the feedback message may further carry information about the pressure of the first consumer node.
In some optional embodiments, the first consumer node may carry, in each case of receiving one message to be consumed, pressure-related information of the first consumer node in a feedback message of the message to be consumed; alternatively, the first consumer node may carry the pressure-related information of the first consumer node in the feedback message of the last received message to be consumed only if the pressure-related information changes.
In practical applications, the first producer node may send a message to be consumed to a plurality of consumer nodes, and, for example, as shown in fig. 4, after each consumer node receives the message to be consumed and completes processing the message to be consumed, a feedback message for the message to be consumed may be sent to the first producer node, where the feedback message carries information related to the pressure of the consumer node. For example, after the consumer node a finishes processing the message a to be consumed, a feedback message for the message a to be consumed may be sent to the first consumer node, where the feedback message carries pressure related information of the consumer node a; after the consumer node B finishes processing the message B to be consumed, a feedback message for the message B to be consumed may be sent to the first consumer node, where the feedback message carries pressure related information of the consumer node B, and so on. Thus, the first producer node can perform load balancing based on the pressure related information of each consumer node, for example, less messages to be consumed are allocated to consumer nodes with higher load pressure, and more messages to be consumed are allocated to consumer nodes with lower load pressure.
According to the message processing method provided by the embodiment of the invention, the first consumer node receives the message to be consumed sent by the first producer node, consumes the message to be consumed, and carries the pressure related information of the first consumer node in the feedback message of the message to be consumed sent to the first producer node.
In some alternative embodiments, the method further comprises:
Transmitting pressure-related information of the first consumer node to the first producer node under the condition that a message to be consumed transmitted by the first producer node is not received within a second preset time period;
or alternatively
And under the condition that a message to be consumed sent by any producer node of at least two producer nodes is not received within a second preset time period, sending pressure related information of the first consumer node to the producer node of the at least two producer nodes, wherein communication connection is established between the first consumer node and the at least two producer nodes, and the at least two producer nodes comprise the first producer node.
In this embodiment, the second preset duration may be set reasonably according to practical situations, for example, 15 minutes, 30 minutes, 1 hour, etc.
In an embodiment, the first consumer node may actively report the pressure related information of the first consumer node to the producer node when the first consumer node does not receive the message to be consumed sent by a certain producer node within the second preset time period, so that each producer node may be guaranteed to directly obtain the latest pressure related information of the first consumer node.
In another embodiment, the first consumer node may actively report the pressure related information of the first consumer node to any one or more of the at least two producer nodes when the message to be consumed sent by any one of the at least two producer nodes is not received within the second preset time period, or may actively report the pressure related information of the first consumer node to a specific one of the at least two producer nodes, for example, may actively report the pressure related information of the first consumer node to a target producer node of the at least two producer nodes, where the message to be consumed received by the first consumer node last time is the message to be consumed sent by the target producer node, so that network resource overhead of reporting the pressure related message by the first consumer node may be saved when the first consumer node interacts with the at least two producer nodes.
In some alternative embodiments, the pressure related information of the consumer node includes at least one of: the pressure index value and the pressure evaluation value of the consumer node;
wherein the pressure evaluation value is determined according to a pressure index value of the consumer node.
In some alternative embodiments, the pressure index value comprises at least one of: disk occupancy, CPU occupancy, memory occupancy, downstream call response time.
The pressure evaluation value may be directly used to evaluate the pressure of the consumer node, for example, the pressure evaluation value may be a pressure score value calculated according to at least one pressure index value, where the greater the pressure score value of the consumer node, the greater the load pressure of the consumer node, and the smaller the pressure score value of the consumer node, the smaller the load pressure of the consumer node.
In an embodiment, each consumer node may report at least one pressure index value, for example, a disk occupancy rate, a CPU occupancy rate, a memory occupancy rate, a downstream call response time, etc., to the producer node, so that the producer node may calculate a load balancing weight value or a load balancing score, etc., corresponding to each consumer node according to the at least one pressure index value reported by each consumer node, respectively, and may perform load balancing based on the load balancing weight value or the load balancing score, etc., corresponding to each consumer node. The method is beneficial to ensuring the consistency of the calculation modes of the load balancing weight values or the load balancing scores corresponding to the consumer nodes, and further improving the accuracy of load balancing.
In another embodiment, each consumer node may report the pressure evaluation value calculated based on at least one pressure index value to the producer node, so that the producer node may directly perform load balancing according to the pressure evaluation value of each consumer node, without performing additional calculation, so that not only the resource overhead of reporting the pressure related information by the consumer node may be reduced, but also the calculation resource of the producer node may be saved.
