Embodiment 1

[0031] figure 1 It is a flowchart of a table implementation method based on a key-value pair storage system provided by Embodiment 1 of the present invention. This embodiment can be applied to how to convert table data into a key-value pair storage system, so that the application layer can It is especially applicable to the scenario of how to implement the management of tabular data on the basis of the underlying storage system of the blockchain, including the key-value pair storage system.

[0032] The following embodiments will be described by taking the conversion of table data in the blockchain system into key-value pairs as an example. Among them, the so-called table is a data structure with rows and columns, and a typical example is an excel table. A table may include at least one row of row data, and the row data includes the specific values ​​of each column according to each column set in the table.

[0033] The method can be implemented by a table implementation dev...

Abstract

The embodiment of the invention discloses a table implementation method and device based on a key value pair storage system, equipment and a medium. The method comprises the steps of obtaining a formdata processing request transmitted by an application layer; determining a key identifier of row data to be processed according to the table data processing request with the key identifier being a numerical value of at least one column in the row data to be processed, and a column corresponding to the key identifier being a key identifier column of the row data; and determining a corresponding rowdata key value pair according to the key identifier, and processing numerical values in the row data key value pair according to the table data processing request, the key domain of the row data keyvalue pair being used for storing the key identifier, and the value domain of the row data key value pair being used for storing the numerical values of row data. By adopting the technical scheme provided by the embodiment of the invention, the data management mode of the table can be realized on the basis of the key value pair storage system of the block chain.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of data storage, and in particular, to a method, device, device and medium for implementing a table based on a key-value pair storage system. Background technique [0002] There are many underlying data storage technologies used in the current blockchain system, and one of the more widely used ones is the Key Value (KV) storage system. Under the control of the application layer of the blockchain system, the KV storage system supports access processing such as data reading and writing of the blockchain system. [0003] In the KV storage system, many key-value pairs are used to store various data that the blockchain system needs to store. However, limited by the data storage structure of the KV storage system, it cannot provide effective support for the increasingly rich storage requirements of the application layer. Typically, people are more accustomed to using tables to manage da...
