Embodiments of the present disclosure provide an information processing method and an information processing apparatus, which may be applied to a blockchain client, and may implement processing of an operation request of a blockchain network for a specific service application through the following operations of the blockchain client. The information processing method may include a pre-storing process, a request receiving process, a request assembling process, and a processing process. In the pre-storing process, the block chain client pre-stores block chain configuration information of a block chain network to which the specified service application belongs. In the request receiving process, the blockchain client receives an operation request from a specified service application, wherein the operation request comprises dynamic parameters. And then, carrying out a request assembly process, and generating a request combination by the block chain client based on the dynamic parameters and the block chain configuration information, wherein the request combination comprises the specified node set information. In the processing process, when monitoring that the designated node set represented by the designated node set information is in an overload state, submitting the request combination to a message queue; and when the designated node set is monitored to be converted from the overload state to the normal state, acquiring a request combination from the message queue and sending the request combination to the designated node set for processing.
Fig. 1 schematically shows an exemplary system architecture 100 to which the information processing method and the information processing apparatus can be applied according to an embodiment of the present disclosure. It should be noted that fig. 1 is only an example of a system architecture to which the embodiments of the present disclosure may be applied to help those skilled in the art understand the technical content of the present disclosure, and does not mean that the embodiments of the present disclosure may not be applied to other devices, systems, environments or scenarios.
As shown in fig. 1, the system architecture 100 may include at least one Blockchain Network (Blockchain Network)110, at least one Blockchain client 120, and at least one service application 130. The block chain network 110 may include nodes 111-116, where the nodes 111-116 collectively maintain a block chain 117.
The block chain technology is a technology for signing transaction information and encrypting and transmitting the transaction information by adopting an asymmetric key, and the scheme is to verify the transaction, assemble blocks and form a block chain structure. The purpose of using block chain technology is to achieve a consensus mechanism, to prevent chain forking, and to achieve distributed network storage by using point-to-point data transmission means. The biggest features of blockchain technology come from its distributed, decentralized, encrypted data storage technology, and reliable underlying mechanisms that do not require third party trust authorities. The block chain network 110 and an excitation mechanism attached to the network form a decentralized self-organizing ecology, nodes in the network follow a uniform rule, data cannot be tampered, data is maintained in multiple nodes, a simple and clear consensus mechanism is achieved, and a trust system formed on the basis does not need to depend on a certain node or a third party and is trust for system rules.
The nodes 111-116 may be various computing nodes with the same or different computing capabilities, such as personal computers, web servers, database servers, and the like, without limitation. Any two of the nodes 111-116 can communicate with each other point-to-point.
It should be understood that the size and type of blockchain network, the number of nodes, the length of blockchain, the number of blocks, etc. in fig. 1 are merely illustrative. According to actual needs, there may be any size and type of blockchain network, any number of nodes, any length of blockchain, any number of blocks, etc., and this is not a limitation here.
With continued reference to fig. 1, according to an embodiment of the present disclosure, the blockchain network 110 may maintain and manage various service data, service functions, service logics, and the like in a predetermined service scenario, and the at least one service application 130 may implement various service functions based on the blockchain network 110. In this scenario, interaction between any service application 130 and a node in blockchain network 110 needs to be by means of blockchain client 120. Blockchain clients 120 are typically custom developed in a manner that provides a Software Development Kit (SDK), or custom developed using various protocols exposed to the outside of the node (e.g., HTTP/HTTPs protocols, GRPC/GRPCs protocols, etc.). Therefore, when the service application 130 needs to access a node on the blockchain network 110, it needs to call the blockchain client 120 to access the blockchain node based on configuration information such as an Application Programming Interface (API), a required channel, a contract, and the like.
In order to avoid uncontrollable situations such as downtime and the like caused by overload of requests, a flow control strategy is executed on a service application side in a processing mode. The flow control comprises a plurality of strategies or combinations of load balancing, access flow limiting, request forwarding, fusing degradation and the like. For example, load balancing builds on existing network architectures, which provides an inexpensive, efficient, transparent way to extend the bandwidth of network devices and servers, increase throughput, enhance network data processing capabilities, and increase network flexibility and availability. Access throttling, forwarding, fusing, etc. are flow control policies for the service interface.
However, the above-described interaction process between the service application and the blockchain network relies on active control of the service application. For example, when a blockchain client accesses a blockchain node, a significant portion of the requests have a long waiting period during which the node processes data to complete uplink operations and returns the results to the blockchain client, which then returns the data to non-client services.
In many scenarios, it is not necessary to obtain results immediately for uplink operation of data, and asynchronous calls are used to improve the throughput of service applications. In the process, regardless of whether the blockchain client adopts clustered deployment or not, the final request pressure falls on the blockchain client, and even if the service application uses technical means such as load balancing and the like to control the blockchain client, whether the blockchain client which is currently requested can continuously receive and process new requests or not cannot be ensured, so that uncontrollable conditions such as downtime and the like of the blockchain client due to overload of the requests can be caused, and when the request data is not persistent, the request is lost, and further data uplink operation failure is caused.
In order to at least partially solve the problem that the blockchain client cannot automatically process the node request traffic in the above process, according to an embodiment of the present disclosure, an information processing method is provided, which may be applied to any blockchain client 120 shown in fig. 1, so as to improve the stability of the request and further improve the execution efficiency. The following description is made by way of example with reference to the accompanying drawings. It should be noted that the sequence numbers of the respective operations in the following methods are merely used as representations of the operations for description, and should not be construed as representing the execution order of the respective operations. The method need not be performed in the exact order shown, unless explicitly stated.
Fig. 2 schematically shows a flow chart of an information processing method according to an embodiment of the present disclosure, which may be applied to a blockchain client.
As shown in fig. 2, the information processing method may include operations S210 to S250.
In operation S210, blockchain configuration information specifying a blockchain network to which the service application belongs is pre-stored.
Illustratively, different service applications may be attributed to different blockchain networks, based on which different business logic may be implemented. The privacy of different service data can be ensured, and the data safety is ensured.
In operation S220, an operation request from a specified service application is received, the operation request including dynamic parameters.
The dynamic parameters are necessary parameters for executing the dynamic change of the operation request, and the data size is small.
In operation S230, a request combination is generated based on the dynamic parameter and the above block chain configuration information.
The request combination comprises appointed node set information, and the appointed node set information is used for representing the nodes of the appointed service application in the block chain network appointed in the current operation request.
In operation S240, when it is monitored that the designated node set characterized by the designated node set information is in an overload state, the request combination is submitted to a message queue.
For example, when there are a plurality of types of designated node sets, monitoring that a designated node set characterized by the designated node set information is in an overload state may refer to monitoring that at least one type of designated node set is in an overload state.
In operation S250, when it is monitored that the designated node set is changed from the overload state to the normal state, the request group is obtained from the message queue and sent to the designated node set for processing.
Illustratively, an overload problem occurs when the data volume load of a given node that needs to perform data processing is found to exceed the maximum load volume. At this time, in order to avoid uncontrollable problems such as downtime of the designated node and avoid loss of the unprocessed request combination, the request combination to be processed may be placed in a message queue. The request combination in the message queue can be processed according to the self load condition of the corresponding designated node, so that the load of the designated node is not continuously increased, and the condition that the request combination is lost is avoided. If the specified node set is monitored to be in the overload state for more than a preset time, namely the specified node set is determined to be continuously overloaded, the blockchain client can start to perform current limiting so as to control the data volume of the operation request. For example, when a new operation request is received, a prompt message is returned to the service application indicating that the traffic has reached the upper limit.
As will be appreciated by those skilled in the art, in the prior art, the blockchain configuration information is loaded on the service application side. And when the service application needs to interact with the block chain network, the service application dynamically generates a request combination based on the block chain configuration information and then sends the request combination to the block chain client for processing. In contrast, according to the information processing method of the embodiment of the present disclosure, the load balancing and the related flow control policy of the service application to the blockchain client are cancelled and all the load balancing and the related flow control policy are handed over to the blockchain client for processing. Blockchain configuration information specifying service applications is pre-stored at the blockchain client side. Therefore, when receiving the operation request from the specified service application, the corresponding request combination can be assembled and generated only by receiving the dynamic parameters with small data size, the block chain configuration information does not need to be assembled and sent by the specified service application, and the flexibility of the request between the service application and the block chain client is realized. In addition, according to the information processing method of the embodiment of the disclosure, after the request combination is assembled and generated by the block chain client, if it is monitored that the overload problem exists in the designated node in the block chain network designated by the request combination, the request combination can be submitted to the message queue, so that the request combination in the message queue can be adaptively processed according to the self load condition of the designated node. And then realize the flow control to the node in the block chain network under the condition of guaranteeing that the request combination will not be lost.
Fig. 3 schematically shows an example schematic diagram of pre-stored block chain configuration information according to an embodiment of the present disclosure.
As shown in fig. 3, the process of pre-storing the block chain configuration information of the block chain network to which the specified service application belongs may include: when the blockchain client 310 first starts, the blockchain client 310 sends a configuration request message to the specified service application 320. Blockchain client 310 then receives and stores the full amount of blockchain configuration information 301 from the specified service application 320. For example, the blockchain client 310 receives and can process more blockchain configuration information, which mainly includes, but is not limited to, for example, blockchain link point set information, blockchain packing node set information, blockchain channel set information, blockchain intelligent contract set information, and blockchain authentication authorization (CA) user set information. The block chain link point set information is used for representing all available block chain node sets in the block chain network. The blockchain packing node set information is used for representing the set of all blockchain packing nodes in the blockchain network. The blockchain channel set information is used to characterize the set of each channel in the blockchain network. Blockchain intelligent contract set information is used to characterize a set of various intelligent contracts deployed in a blockchain network. Blockchain authenticated authorized user set information is used to characterize a set of users that have undergone a data certificate issuance process. The block chain node and the block chain packing node are nodes with different authorities in the block chain network, for example, the block chain node is used for receiving data, and the block chain packing node is used for packing blocks.
With continued reference to fig. 3, the process of pre-storing the blockchain configuration information of the blockchain network to which the specified service application belongs may further include: each time the blockchain configuration information of the blockchain network is updated, the blockchain client 310 receives incremental blockchain configuration information from the specified service application 320, where the incremental blockchain configuration information refers to a portion of the blockchain configuration information that is changed. Then, based on the incremental blockchain configuration information, the full-amount blockchain configuration information is updated.
The above block chain configuration information may be assembled by matching different parameters in different requests, and is described as an example with reference to fig. 4. Fig. 4 schematically illustrates an example schematic diagram of request combining according to an embodiment of the disclosure.
For example, the operation request is an uplink request, and the dynamic parameter is a first dynamic parameter for the uplink request. Based on the dynamic parameters and the blockchain configuration information, the generated first request combination 401 may be as shown in fig. 4, and represent that the first designated blockchain node, the first designated packing node, the first designated channel, the first designated intelligent contract, and the first designated CA user combination are used when initiating the data uplink request. The generating of the request combination based on the dynamic parameters and the blockchain configuration information may include: based on a first dynamic parameter, selecting first appointed available node set information from the block chain node set information, selecting first appointed packing node set information from the block chain packing node set information, selecting first appointed channel set information from the block chain channel set information, selecting first appointed intelligent contract set information from the block chain intelligent contract set information, and selecting first appointed user set information from the block chain authentication authorized user set information. Then, the first designated available node set information, the first designated packing node set information, the first designated channel set information, the first designated intelligent contract set information and the first designated user set information constitute a first request combination for uplink requests.
For another example, the operation request includes an on-chain query request, and the dynamic parameter is a second dynamic parameter for the on-chain query request. Based on the dynamic parameters and blockchain configuration information, a generated second request combination 402 may be characterized as shown in fig. 4 as a second specified blockchain node, a second specified channel, a second specified smart contract, and a second specified CA user combination to be used when initiating the on-chain query request. The generating the request combination based on the dynamic parameter and the block chain configuration information includes: based on a second dynamic parameter, selecting second specified available node set information from the blockchain node set information, selecting second specified channel set information from the blockchain channel set information, selecting second specified intelligent contract set information from the blockchain intelligent contract set information, and selecting second specified user set information from the blockchain authentication authorized user set information. Then, a second request combination for the on-chain inquiry request is formed by the second specified available node set information, the second specified channel set information, the second specified intelligent contract set information and the second specified user set information.
For another example, the operation request includes a channel query request, and the dynamic parameter is a third dynamic parameter for the channel query request. Based on the dynamic parameters and the blockchain configuration information, the generated third request combination 403 may be as shown in fig. 4, which indicates that a third designated blockchain node, a third designated channel, and a third designated CA user combination are to be used when initiating query channel information. The generating the request combination based on the dynamic parameter and the block chain configuration information includes: and based on a third dynamic parameter, selecting third appointed available node set information from the blockchain node set information, selecting third appointed channel set information from the blockchain channel set information, and selecting third appointed user set information from the blockchain authentication authorized user set information. Then, a third request combination for the channel query request is formed by the third designated available node set information, the third designated channel set information, and the third designated user set information.
In addition to the above, there are a plurality of request combinations covering the life cycle of the blockchain, such as creating a channel, joining a channel, installing a contract, instantiating a contract, upgrading a contract, discovering a node service, and creating a CA user. The process of assembling and generating the corresponding request combination is the same as the principle of the above example, and is not described herein again. In one embodiment of the present disclosure, the set required by the request combination may be generated in advance or dynamically generated by the service application, and in combination with the organizational object deploying the current blockchain node, the information of the set is clear even if dynamically generated.
In view of this, all possible combinations of requests are delivered to the blockchain client for assembly, rather than being handled by a non-client service, and the service application sends all known aggregation information to the blockchain client when starting up, and synchronously sends subsequent possible changes of the configuration aggregation information to the blockchain client, thereby ensuring that the blockchain client always retains the latest blockchain link point configuration information set. At this time, when the non-client service initiates any blockchain request, only the necessary parameters which are dynamically changed need to be provided, and the configuration information does not need to be assembled and sent, thereby realizing the flexibility of the request.
And when the blockchain client receives a request initiated by a non-client service, selecting an available node set and a packaging node set according to specific request content. The packing node provides a packing service node by using the node and the block link node. The two node sets are many-to-many and not necessarily equal in number. There may be situations where the node set is overloaded and the packing node set can continue to process traffic, or where the packing node set is overloaded and the node set can continue to process traffic. In this case, the requests of the two types of sets need to be subjected to flow control except load balancing according to different situations, so as to ensure that each request can be processed.
According to an embodiment of the present disclosure, the information on the set of designated nodes may include: specifying available node set information and/or specifying packed node set information. On the basis, the overload of the designated node set characterized by the designated node set information includes at least one of the following items: the designated block chain node set represented by the designated available node set information is overloaded; and overload occurs to the specified packing node set represented by the specified packing node set information.
It will be appreciated that to ensure that requests are processed, the combination of requests being flow controlled will be submitted to a message queue in the event of an overload condition in either of the above two categories, and that message queue services that may be used include, but are not limited to, for example, Kafka message queues, ActiveMQ, RibbitMQ, rocktmq, and the like, without limitation.
Fig. 5 schematically shows an example schematic diagram of an information processing method according to another embodiment of the present disclosure to illustrate an interaction process between the blockchain client 510 and the service application 520, and between the blockchain client 510 and the blockchain network. In this example, service application 520 is a non-client service 520. The blockchain network includes blockchain nodes 531 and blockchain packing nodes 532. A message middleware, i.e., a message queue 540, is also provided.
As shown in fig. 5, when the non-client service 520 is started, the basic information of the blockchain organization to which the current service belongs, i.e., the blockchain configuration information, is loaded from the relevant data provider such as a database or a local file. If the blockchain configuration information exists, the blockchain configuration information related to the current organization is loaded and sent to the blockchain client 510. At this time, if the blockchain client 510 is not started, the non-client service 520 sends the locally existing currently organization-related blockchain configuration information to the blockchain client 510 when receiving the request sent by the blockchain client 510 for the first time.
When the non-client service 520 monitors that the block chain configuration information related to the current organization is changed, the synchronization information is sent to the block chain client 510, and if the block chain client does not exist, the above loading of the block chain configuration information related to the current organization is repeated and the block chain configuration information is sent to the block chain client 510.
When non-client service 520 initiates a blockchain related operation request, the necessary dynamic parameter request is sent to blockchain client 510. The blockchain client 510 selects a designated available node set and a designated packed node set according to a request policy, and initiates a request for a node in a load balancing manner according to the current availability of the sets. And if any one of the appointed available node set and the appointed packing node set is overloaded, performing fusing processing on a newly received request, and forwarding the newly received request to a message queue service. If a persistent overload request is required, the blockchain client 510 is throttled to ensure stable operation of the blockchain client 510.
Based on the above embodiments, it can be understood that according to the embodiments of the present disclosure, the fault tolerance capability of the blockchain client can be improved, it is ensured that each request can be successfully consumed, and meanwhile, the high concurrency capability of the service is more accurately improved.
