Detailed Description
Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to like or similar elements or elements having like or similar functions throughout. The embodiments described below by referring to the drawings are illustrative and intended to explain the present invention and should not be construed as limiting the invention.
The following describes a blockchain data acquisition method and apparatus according to an embodiment of the present invention with reference to the accompanying drawings.
Aiming at the technical problem that the statistical requirement is difficult to meet due to the fact that the existing statistical mode depends on information recorded in a blockchain account book, the invention provides a novel multi-element storage mode of blockchain data, wherein the multi-element storage mode stores the statistical requirement, and the statistical requirement is met.
In addition, the data storage mode provided by the embodiment of the invention does not need to upgrade and reform the blockchain, reform the blockchain code and change the data compatibility of the data in the blockchain ledger.
Specifically, fig. 1 is a flowchart of a blockchain data acquisition method according to an embodiment of the present invention. The execution main body of the blockchain data acquisition method of the embodiment of the invention can be an independent third party data statistics platform, thereby being convenient for data statistics management and maintenance without modifying a blockchain system, as shown in fig. 1, and the blockchain data acquisition method comprises the following steps:
step 101, receiving standard data information converted according to a preset standard format sent by a target block chain system.
In this embodiment, the preset standard format may be a data format that is specified by the third party data statistics platform and is convenient to manage, and as a possible implementation manner, the standard format is a Binlog format, and the Binlog format is shown in fig. 2.
Of course, in order to facilitate the feedback data of each blockchain in the standard format, a standard format is also sent to each blockchain system in advance, where the standard format includes: a behavior description field, a behavior parameter field, a behavior result field, wherein the behavior description field includes content of an execution behavior, executor identification information of the execution behavior, etc., the behavior parameter field includes a specific parameter of the content of the execution, etc., and the execution result field generally includes whether an execution result is failure or success, etc.
Taking contract call corresponding data as an example, the corresponding standard format is: the caller name contract parameter contract execution output, where caller and contract name may be understood as behavior description fields, contract parameter may be understood as behavior parameter fields, and contract execution output may be understood as behavior result fields.
Wherein the behavior description field may be described in terms of simple discernable characters as shown in fig. 2, i.e., in terms of CI, where CI is the conteractinvoke field in fig. 2.
Step 102, obtaining index information pre-configured by the target block chain system.
It can be appreciated that, if the blockchain wants to perform data statistics on the corresponding platform, the blockchain needs to be configured in advance, so in the embodiment of the present invention, index information pre-configured by the target blockchain system needs to be acquired. Wherein the index information may include a statistical index to the standard data information.
In some possible embodiments, a correspondence between the blockchain type of the blockchain system and the index information may be pre-constructed, where the correspondence may be summarized according to empirical data, and then the correspondence is queried to obtain the corresponding index information.
In some possible embodiments, general index information preconfigured by the target blockchain system may be obtained, and a first processing period corresponding to the general index information, where the general index information may include behavior configuration and the like, and the first processing period may include how often corresponding data corresponding to the behavior configuration is counted.
Continuing with the example of a contract invocation scenario, the generic configuration may include a configuration of the contract execution behavior, specifically in the CI field, and a first processing cycle of the contract execution behavior of 1 minute.
In some possible examples, the index information corresponds to a field, and in this example, to further flexibly meet the statistical requirement, the preconfigured index information may further include: acquiring at least one keyword index corresponding to the universal index information and configured in advance by the target blockchain system, and a second processing period corresponding to each keyword index, wherein the at least one keyword index can be a processing index of a keyword of a part of fields corresponding to the universal index information, for example, the processing index of the keyword field comprises: statistics keywords, exclusion keywords, convergence fields (statistics index), etc.;
continuing with the contract call example, the keyword index may include a pair statistics field: the setting of the contract name may include setting of the statistical keyword a, may include setting of the exclusion keyword b, and may include a degree exclusion field: setting of contract names, etc.
And 103, analyzing the standard data information to obtain a target field corresponding to the index information, and judging whether the content of the target field is matched with the index information.
In this embodiment, the standard data information is analyzed to obtain the target field corresponding to the index information, and whether the content of the target field matches with the index information is determined, for example, whether the keyword field contains the keyword indicated in the index information or not is determined, so as to meet the corresponding screening statistical requirement.
For another example, when the target field is a contract name field, it is determined whether the contract name field is a contract name or the like corresponding to index information set in advance so as to satisfy aggregation or the like of data of all contracts corresponding to the contract name.
And 104, if the content of the target field is successfully matched with the index information, accumulating the data result corresponding to the index information in the current cache.
In this embodiment, if the content of the target field is successfully matched with the index information, the data results corresponding to the index information in the current buffer are accumulated, that is, the data results corresponding to all the index information are statistically accumulated, so as to generate a total accumulated processing result.
For example, if the target field is a contract name field and the corresponding index information is all contract data with the statistical contract name a, the accumulated statistics is performed on all contract data with the contract name field a.
As mentioned above, the index information has a corresponding processing period, in order to avoid memory overflow, the cache is cleaned according to the processing period, that is, whether a preset processing period corresponding to the index information is reached, for example, whether a second processing period corresponding to each keyword index is reached, etc., and if the processing period corresponding to the index information is reached, the data result corresponding to the index information in the current cache is cleared, so as to release the memory, where the accumulation of the data result in the processing period may be stored in the database corresponding to the blockchain system.
To make it clear to those skilled in the art how to acquire blockchain data in the present invention, a contract invoking scenario is specifically described below, where in the following embodiment, a preset standard format is described below as a binlog example:
in this example, the data acquisition of the blockchain may be performed by a specific data processing module, as shown in fig. 3, wherein with reference to fig. 3, the data receiving module receives standard data information in binlog format sent from the respective blockchain system over a network or otherwise. The data distribution module is used for distributing according to the pre-configured index information of the account book in the binlog and the level of the account book, the data statistics module is used for receiving the data distributed by the data distribution module and carrying out data statistics on target content meeting the index information, wherein the data listing module is used for listing the statistical result and storing the accumulated data result in the database so as to prevent the communication information from being lost (generally realized by the database). In this scenario, to facilitate the traceability of the blockchain system to the accumulated data results, the database also provides an SDK interface for clients used by each blockchain system.
When processing standard data information, referring to fig. 4, the specific process starts a timer first, monitors the standard data information converted according to a preset standard format sent by a target blockchain system in real time, performs data analysis on the obtained data, and determines whether the information belongs to data of a field corresponding to the preset standard format, so as to determine whether the obtained new data needs to be counted.
If the statistics are not needed, continuing to monitor. If statistics is needed, statistics information corresponding to index information in the cache (the data result corresponding to the index information mentioned above) is obtained, at this time, whether the customizer meets a preset time rule (namely, whether a preset processing period is reached) is judged, whether statistics is needed for internal data of new data is analyzed, namely, standard data information is analyzed to obtain a target field corresponding to the index information, whether the content of the target field is matched with the index information is judged, and if so, accumulation processing is carried out on the data result corresponding to the index information in the current cache. And meanwhile, monitoring whether a preset processing period corresponding to the index information is reached, if so, performing landing storage on the corresponding data result, and clearing the data result corresponding to the index information in the current cache.
In summary, the blockchain data acquisition method of the embodiment of the invention receives standard data information converted according to the preset standard format sent by the target blockchain system, further acquires index information pre-configured by the target blockchain system, analyzes the standard data information to acquire a target field corresponding to the index information, judges whether the content of the target field is matched with the index information, and finally, if the content of the target field is successfully matched with the index information, performs accumulation processing on a data result corresponding to the index information in the current cache.
