Abstract

The invention discloses a financial data storage method and device based on HBase and a storage medium. The method comprises the following steps: calling a financial data file; generating a row key according to parameter values of a plurality of attributes included in the financial data file, the plurality of attributes including at least one of the following items: stock code, stock type, transaction date and transaction time; and importing financial data in the financial data file into an HBase storage system according to the row key. According to the method and the device, a large amount oftransaction data in the financial field are stored in the HBase storage system, so that the technical effects of reasonable storage of the financial data and rapid query and calculation of services are realized. Furthermore, the technical problem that in the prior art, due to the fact that financial data are stored in a relational database, a local disk or a data warehouse, reasonable storage, high-frequency query and rapid calculation of mass financial data cannot be achieved is solved.

Description

technical field [0001] The present application relates to the field of financial data storage, in particular to an HBase-based financial data storage method, device and storage medium. Background technique [0002] Financial data, involving stocks, options, futures in the financial field, and data records from the opening to the closing of each trading day, the data records are at the millisecond level, resulting in a relatively large historical base and daily increment of such data, such a massive amount of historical data And daily incremental data poses a huge challenge to the fast query and analysis of storage devices and services. At present, financial data is stored and processed mainly by relational database or directly stored on local disk. The storage and query calculation efficiency of this kind of storage method is low, and it cannot serve the quantitative analysis and trading business in the financial field with the characteristics of high frequency, real time, ...
