Detailed Description
The core of the application is to provide a block chain data storage method, a block chain data storage device, a server and a computer readable storage medium, wherein a corresponding sequence number is obtained by calculating a block file, and then the block file is directly written in as the file name of a directory area and is directly written in a cluster address of a storage space with the same size as the block file, so that the condition that a plurality of cluster addresses are written in a linked list for storage is avoided, the data writing efficiency is improved, and the storage performance of storage relation data is simpler and improved.
In order to make the objects, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are some embodiments of the present application, but not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
In the related art, the blockchain storage technology essentially uses each blockchain storage system as the minimum storage unit to manage, and uses the characteristics of blockchains and distributed storage to achieve the functions of confidentiality, data fault-tolerant backup and the like at a protocol layer or a software application layer. However, no compatible storage system can perform more adaptive storage operation on the blockchain, which reduces the storage performance of blockchain data in the storage system and limits the performance of blockchain data in the storage system.
Therefore, the block chain data storage method provided by the application obtains the corresponding serial number by calculating the block file, and then directly writes the serial number as the file name of the directory area, and directly writes the serial number into the cluster address of the storage space with the same size as the block file, thereby avoiding writing a plurality of cluster addresses into a chain table for storage, improving the data writing efficiency, simplifying the storage relation data and improving the storage performance. Therefore, when the block file is read, the cluster address can be directly determined from the directory area through the serial number of the block file, and corresponding data can be directly acquired according to the cluster address.
A method for storing block chain data provided by the present application is described below by an embodiment.
Referring to fig. 1, fig. 1 is a flowchart illustrating a method for storing block chain data according to an embodiment of the present disclosure.
In this embodiment, the method may include:
s101, calculating a unique serial number of a block file to obtain a serial number;
this step is intended to perform unique sequence number calculation processing on the block file to obtain a sequence number.
The unique serial number calculation processing performed in this step may adopt any one of calculation methods provided in the related art, and may adopt a hash value calculation method, which is not specifically limited herein.
In this embodiment, the blockchain file is mainly stored as the blockchain file. In order to determine the blockchain file or the blockfile in the storage system or the storage structure, a unique serial number calculation process may be performed on the blockfile to obtain a serial number. And recording the sequence number in a corresponding position so as to determine a corresponding block file according to the sequence number.
The block file may be a single blockchain file, or may be a plurality of blockchain files obtained by decomposing a blockchain file when the blockchain file is large. As can be seen, in this embodiment, how to acquire the blockchain file may be determined according to the size of the blockchain file, and an acquisition mode may be selected according to an actual application situation, which is not specifically limited herein.
Further, in order to improve the storage performance and the storage reliability of the blockchain file, before this step, the method may further include:
and decomposing the block chain file according to the performance of the storage system to obtain a plurality of block files.
The performance of the storage system may be a bandwidth of the storage system, a size of a storage space corresponding to each cluster address in the storage system, or a size of a remaining space of each storage unit in the storage system. It is to be understood that the performance of the storage system used in the embodiments of the present application is not exclusive and is not limited herein.
Optionally, this step may include:
and calculating the block file according to a Hash algorithm to obtain a sequence number.
It can be seen that the present alternative scheme mainly explains how to perform the unique serial number calculation. In the alternative scheme, a hash algorithm is mainly adopted to perform corresponding calculation to obtain the sequence number.
S102, writing the serial number corresponding to the block file into a directory area as a file name in the directory area, and writing the serial number into a corresponding cluster address; the size of a storage space corresponding to the cluster address is the same as the size of the block file;
on the basis of S101, this step is intended to write the serial number corresponding to the block file as the file name in the directory area into the directory area, and write the corresponding cluster address. The size of the storage space corresponding to the cluster address may be the same as the size of the block file, or may be larger than the size of the block file. That is, when the block file is written into the data area, the block file can be directly written into the storage space corresponding to one cluster address, instead of writing the block file into the storage spaces corresponding to a plurality of cluster addresses respectively. That is, one cluster address corresponds to one block file, and data in the data area can be determined only by finding one cluster address, but data in the data area can be determined without finding a plurality of cluster addresses.
Wherein, the size of the storage space corresponding to the cluster address is the same as the size of the block file. The block file may be divided into the same size as the storage space corresponding to the cluster address, or the storage space corresponding to the cluster address may be set to a larger value, and then the block file may be divided into the same size files for storage. The size of the storage space corresponding to the cluster address may also be set to a value equal to the size of the block file.
Optionally, this embodiment may further include:
step 1, acquiring a file size value of a block file;
and step 2, setting the storage space value corresponding to each cluster address in the data area as a block file size value.
It can be seen that the present alternative scheme mainly explains how to set the size of the storage space corresponding to the cluster. In the related art, the size of the storage space corresponding to a general cluster address is fixed, and there is no way to change the storage space, so when a block file is stored in a data area, a plurality of storage spaces corresponding to virtual addresses need to be used, which causes redundant steps in the using process. Therefore, in the present embodiment, the storage space value corresponding to the cluster address is set to the same size as the tile file.
S103, writing the block file into a storage space corresponding to the cluster address in the data area.
On the basis of S102, this step is intended to write the block file into the storage space corresponding to the cluster address in the data area. Therefore, in this step, only the block file needs to be written into the storage space corresponding to one cluster address.
Further, in order to improve efficiency in the data reading process and reduce the address lookup time, this embodiment may further include:
step 1, when a serial number of a block file to be read is received, searching a corresponding cluster address in a directory area according to the serial number of the block file to be read;
and step 2, acquiring the block file to be read from the data area according to the cluster address.
It can be seen that the present alternative is mainly described how to read the tile file. In this alternative, the serial number of the block file to be read is received first, then the corresponding cluster address is found directly in the directory area according to the serial number of the block file to be read, and finally the corresponding block file is obtained according to the cluster address.
In summary, in the embodiment, the block file is calculated to obtain the corresponding sequence number, and then the corresponding sequence number is directly written as the file name of the directory area, and the cluster address of the storage space with the same size as the block file is directly written, so that writing of multiple cluster addresses into a linked list for storage is avoided, the efficiency of data writing is improved, and the storage performance is improved by making the storage relation data simpler. Therefore, when the block file is read, the cluster address can be directly determined from the directory area through the serial number of the block file, and corresponding data can be directly acquired according to the cluster address.
A method for storing block chain data provided by the present application is described below with reference to an embodiment.
In this embodiment, first, in order to optimize the clusters of the data area, the size of the clusters is set to the size of the block file, so that the use search time is reduced. Secondly, in order to simplify the directory structure in the storage system, the directory structure and the mapping to the data area are simplified. Specifically, the block file sequence number in the directory area represents the file name of each block file, and the address recorded in the directory area corresponds to the cluster address of the block file in the hard disk data area.
Based on this, the process of writing the blockchain file and the process of reading the blockchain file in the method comprise the following steps:
writing a block chain file: the block chain file is decomposed into a plurality of block files, the serial numbers of the blocks and the contents of the block files are received, the serial numbers of the block files are used as file names to be written into a directory area, then the data area cluster addresses corresponding to the block files are written into, and finally the contents of the block files are written into a storage space corresponding to the cluster addresses in the data area.
Reading a block chain file: when the CID which needs to be read is received, the corresponding block content can be obtained from the hard disk data area and returned only by searching the corresponding cluster address in the directory area.
Therefore, in the embodiment, the corresponding sequence number can be obtained by calculating the block file, and then the corresponding sequence number is directly written as the file name of the directory area, and the cluster address of the storage space with the same size as the block file is directly written, so that the situation that a plurality of cluster addresses are written into a linked list for storage is avoided, the data writing efficiency is improved, and the storage performance is improved by enabling the storage relation data to be simpler. Therefore, when the block file is read, the cluster address can be directly determined from the directory area through the serial number of the block file, and corresponding data can be directly acquired according to the cluster address.
In the following, the blockchain data storage device provided by the embodiment of the present application is introduced, and the blockchain data storage device described below and the blockchain data storage method described above may be referred to correspondingly.
