Detailed Description
Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the drawings are illustrative and intended to be illustrative of the invention and are not to be construed as limiting the invention.
The block chain data acquisition method and apparatus according to an embodiment of the present invention are described below with reference to the drawings.
In view of the above-mentioned technical problems in the background art, the present invention provides a new multivariate storage method for blockchain data, which stores data along with the statistical requirements of blockchain data, and meets the statistical requirements, in the prior art, the statistical method depends on information recorded in a blockchain ledger, thereby making the statistical requirements difficult to meet.
In addition, the data storage method provided by the embodiment of the invention does not need to upgrade and modify the blockchain, modify the blockchain code, and modify the data compatibility of the data in the blockchain account book.
Specifically, fig. 1 is a flowchart illustrating a method for acquiring block chain data according to an embodiment of the present invention. The execution main body of the block chain data acquisition method in the embodiment of the present invention may be an independent third-party data statistics platform, so that statistics management and maintenance of data are facilitated, and a block chain system does not need to be modified, as shown in fig. 1, the block chain data acquisition method includes the following steps:
In this embodiment, the preset standard format may be a data format which is convenient for management and is statistically specified by a third-party data statistics platform, and as a possible implementation manner, the preset standard format is a Binlog format, and the Binlog format is as shown in fig. 2.
Certainly, in order to facilitate each blockchain to adopt the standard format feedback data, a standard format is also sent to each blockchain system in advance, where the standard format includes: the system comprises a behavior description field, a behavior parameter field and a behavior result field, wherein the behavior description field comprises the content of an execution behavior, the executor identification information of the execution behavior and the like, the behavior parameter field comprises specific parameters of the content of the execution and the like, and the execution result field generally comprises the failure or success of the execution result and the like.
Taking the contract calling corresponding data as an example, the corresponding standard format is as follows: the method includes the steps of | caller | contract name | contract parameter | contract execution output |, wherein the caller and the contract name can be understood as a behavior description field, the contract parameter can be understood as a behavior parameter field, and the contract execution output can be understood as a behavior result field.
The behavior description field may be described by using simple recognizable characters as shown in fig. 2, i.e. by using CI, where CI is the contectinvoke field in fig. 2.
It can be understood that, if the blockchain wants to perform data statistics on the corresponding platform, it needs to be configured in advance, and therefore, in the embodiment of the present invention, index information pre-configured by the target blockchain system also needs to be obtained. The index information may include a statistical index of the standard data information.
In some possible embodiments, a corresponding relationship between the type of the block chain system and the index information may be pre-constructed, and the corresponding relationship may be summarized according to empirical data, and then the corresponding relationship is queried to obtain the corresponding index information.
In some possible embodiments, general index information pre-configured 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 a behavior configuration and the like, and the first processing period may include data corresponding to how often the corresponding behavior configuration is counted.
Continuing with the contract invocation scenario as an example, the general configuration may include a configuration of the contract execution behavior, specifically configured in the CI field, and configuring the first processing period of the contract execution behavior to be 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 general 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 may be a processing index of a keyword in a partial field corresponding to the general index information, and for example, the processing index of the keyword field includes: statistics of keywords, exclusion of keywords, convergence fields (statistical indexes), and the like;
continuing with the contract invocation example, the keyword indicators may include a pair statistics field: the contract name setting may include setting of a statistical keyword a, may include setting of an exclusion keyword b, and may include a degree exclusion field: the 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 a target field corresponding to the index information, and whether the content of the target field matches the index information is determined, for example, whether a keyword field includes a keyword indicated in the index information is determined, so as to meet the corresponding requirement of the screening statistics.
For another example, when the target field is a contract name field, it is determined whether the contract name field is a contract name corresponding to preset index information, so as to satisfy aggregation 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 cache are accumulated, that is, the data results corresponding to all the index information are subjected to statistical accumulation processing, and the like, 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 a statistical contract name a, the cumulative statistics is performed on all contract data with a contract name field a.
As mentioned above, the index information has a corresponding processing cycle, and in order to avoid memory overflow, the cache is cleared according to the processing cycle, that is, whether a preset processing cycle corresponding to the index information is reached is detected, for example, whether a second processing cycle corresponding to each keyword index is reached, and if the processing cycle corresponding to the index information is reached, the data result corresponding to the index information in the current cache is cleared to release the memory, wherein the accumulation of the data result in the processing cycle may be stored in the database corresponding to the block chain system.
In order to make it clear for those skilled in the art how to acquire the blockchain data in the present invention, a contract invocation scenario is specifically described below, where in the following embodiment, a predetermined standard format is binlog as an example, and the following description is provided:
in this example, as shown in fig. 3, the data acquisition of the block chain may be performed by a specific data processing module, wherein, referring to fig. 3, the data receiving module receives the standard data information in binlog format transmitted from each block chain system through a network or other means. 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 the target content meeting the index information, the data destaging module is used for destaging the statistical result and storing the accumulated data result in the database so as to prevent communication information from being lost (usually realized by adopting the database). In this scenario, in order to facilitate tracing of the accumulated data result by the blockchain system, the database also provides an SDK interface for the client used by each blockchain system.
When standard data information is processed, referring to fig. 4 in a specific process, a timer is started, standard data information which is transmitted by a target block chain system and converted according to a preset standard format is monitored in real time, data analysis is performed on the obtained data, whether the information belongs to data of a field corresponding to the preset standard format is judged, and whether the obtained new data needs to be counted is determined.
If no statistics are needed, monitoring is continued. If the statistics is needed, the statistical information corresponding to the index information in the cache (the data result corresponding to the mentioned index information) is obtained, at this time, whether the customizer meets a preset time rule (that is, whether a preset processing period is reached) is judged, whether the data in the new data needs to be counted is analyzed, that is, the 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 the content of the target field is matched with the index information, the data result corresponding to the index information in the current cache is subjected to accumulation processing. And meanwhile, monitoring whether a preset processing period corresponding to the index information is reached, if the processing period corresponding to the index information is reached, performing disk-dropping storage on the corresponding data result, and clearing the data result corresponding to the index information in the current cache.
