First embodiment
Referring to fig. 3, fig. 3 is a flowchart of a data sharing method according to a first embodiment of the present invention, where the method is applied to a data sharing platform. The flow shown in fig. 3 will be described in detail from the perspective of the data provider, and it should be noted that the data provider can also be used as the data acquisition end in the next flow. The method comprises the following steps:
step S110: and when the data providing end acquires the data sharing request, preprocessing the data to be shared to obtain the log information corresponding to the shared data.
Referring to fig. 4, the data provider may include: DB server, PD server and KV server connected with each other.
The DB Server (database Server) is responsible for receiving SQL request initiated by a user to process SQL related logic, and the request represents that data to be shared is shared. The PD Server finds the KV address storing the data to be shared in the KV Server, interacts with the KV Server to acquire the data, and returns the final result.
The DB Server is stateless, does not store data, can be expanded infinitely horizontally, and can provide a uniform access address for the outside through the load balancing component.
The PD Server is a management module of the whole cluster, and is mainly responsible for three tasks: storing meta-information of the cluster (such as which KV node a certain key is stored in); scheduling and load balancing (such as data migration) are carried out on the KV nodes; a globally unique and incremented transaction ID is assigned.
The KV Server is responsible for data storage, and is a Key-Value storage engine which is distributed and provides transactions when viewed from the outside. The basic unit for storing data is a Region, each Region stores a segment of Key Range data, each KV Server is responsible for data of a plurality of regions, and a Range protocol is used for copying the data, so that the consistency and disaster tolerance of the data are ensured. The copy is managed by taking Region as a unit, and a plurality of regions on different nodes form a raw Group which are mutually copies.
By the above architecture, the problems of low data access and low operation performance when the traditional database (such as Oracle, MySQL, SQL Server and the like) stores extremely large data volume (such as more than one billion rows of data per table) can be solved. Meanwhile, the theoretical data storage scale is only limited by the size of the disk, when the disk is not enough, only the disk needs to be simply added, the PDServer can automatically schedule data to the newly added disk, and the performance of data operation (such as query insertion update and the like) cannot be obviously reduced.
In the embodiment of the invention, the DB Server is used as an analysis layer to perform protocol conversion between the PD Server and the KV Server, so that the PD Server and the KV Server can be compatible.
And the PD server calculates the KV address of the shared data in the KV server and then interacts with the KV server to acquire the log information.
Wherein the log information includes but is not limited to: and storing the ID of the database of the data to be shared, a binary log (binlog) generated by the database, log generation time, product information of the database and version information of the database.
Step S120: and the data providing end synchronizes the log information to the block chain through the block chain network interface, so that the block chain network interface synchronizes the log information to the data acquisition end from the block chain when acquiring a data downloading request of the data acquisition end.
After the data providing end obtains the log information, the log information can be obtained through a daemon process (Pump) deployed on the DB server, and then the log information is written into the card-card cluster in real time. And then sequentially synchronizing the log information to the block chain according to the sequence of the writing time. Because the card cluster is a distributed cluster, data can be stored in multiple copies for backup, and therefore log information can be prevented from being lost.
The data providing end can obtain a public key and a private key which are matched with each other and are issued by an authentication server CA of the block chain, then the log information is signed by the private key and then is sent to the block chain, and therefore the data obtaining end can obtain the log information through the public key.
The block chain can comprise endorsement nodes, sorting nodes and accounting nodes, the data providing end can submit the log information signed by a private key to the endorsement nodes (Endorser), the Endorser returns the endorsement information to the data providing end after receiving the log information, then the data providing end submits the endorsement information to the sorting nodes (Orderer), the Orderer sorts and packs the log information into the blocks, then the Orderer sends the log information to the accounting nodes (Committer), and the Committer stores the log information into the Ledger (block chain).
Each node maintains an account book copy of the log information. The consistency of the log information is maintained by Orderer, and the Orderer does not save the log information. And synchronously copying the log information of each node based on the channel. Different nodes are organized and managed based on managers, and nodes in the same manager have the same authority. The identity of the administrator is identified by a certificate issued by the CA server.
When the data acquisition end is connected to different nodes on the block chain, as long as the data is successfully synchronized on the connected nodes, the data acquisition end can acquire all log information required to be synchronized by traversing the whole account book and locally finish restoration, so that the purpose of data sharing is achieved.
In the data sharing method provided by the first embodiment of the present invention, when acquiring a data sharing request, a data providing end preprocesses data to be shared to obtain log information corresponding to the shared data; and the data providing end synchronizes the log information to the block chain through the block chain network interface, so that the block chain network interface synchronizes the log information to the data acquisition end from the block chain when acquiring a data downloading request of the data acquisition end. The log information of the database in the whole process is used as data shared by the block chain, the data chaining in the database and the data in the block chain are led into the database through the block chain network interface, and the reliability of the data is guaranteed while the data sharing is realized.
