Embodiment Construction

[0031] The technical solutions of the present invention will be further elaborated below in conjunction with the accompanying drawings and specific embodiments.

[0032] The present invention provides a method and system for real-time data storage. The system determines the number of memory-mapped blocks in a memory-mapped file according to preset configuration information, and then divides the memory-mapped file into blocks according to the determined number of memory-mapped blocks. , and then perform real-time data access operations in units of memory mapping blocks, so that the system can process multiple data requests in parallel. The specific operation process is as figure 1 As shown, it mainly includes the following steps:

[0033] Step 101, read configuration information from the database when the system starts.

[0034] The configuration information is pre-set by the user according to actual needs and stored in the database. When the system starts, the configuration ...

Abstract

The invention discloses a method for real-time data memory, comprising the following steps of: reading prearranged configuration information, determining the quantity of the memory mapping blocks according to the configuration information of the reading, partitioning the memory mapping file according to the quantity of the memory mapping blocks, and executing the real-time access operation of the data by taking the memory mapping block as a unit. The invention also discloses a system for real-time data memory; the way of accessing of memory mapping file by partition is adopted so that the system can process a plurality of data requests in parallel, thus improving the system performance; as the quantity of the partitions can be configured according to practical requirement, the proposal has good expansibility.

Description

technical field [0001] The invention relates to real-time data storage technology, in particular to a method and system for real-time data storage. Background technique [0002] With the integration of the information industry and the financial industry, the informationization level and service level of the financial industry have been greatly developed. At present, the data volume, data types and data complexity of the financial industry have reached a certain scale and degree. With the business innovation in the financial industry, a series of services such as real-time market quotations and mobile wallets have been developed, and these services are inseparable from the storage of real-time data. [0003] Most of the current real-time data storage solutions use memory-mapped file technology, specifically: first store data in a memory-mapped file, and each product (the basic unit of storage) has its own space in the memory-mapped file. When the space is occupied by data t...
