Abstract

The invention relates to the technical field of data updating, and discloses a cold and hot data storage method and device and an electronic device. The method comprises the following steps: backing up hot data in a hot database to a cold database; wherein the hot database is used for storing hot data, and the cold database is used for storing cold data; wherein the hot data is data with the dataaccess frequency greater than or equal to the preset access frequency within the target time length, and the cold data is data with the data access frequency less than the preset access frequency within the target time length; judging whether target hot data converted into cold data exist in the hot database or not; and if the target hot data exists, deleting the target hot data from the hot database. According to the embodiment of the invention, the hot database with high real-time performance and high cost can store the hot data frequently accessed by the nodes, and the cold database with low real-time performance and low cost can store the cold data which are not frequently accessed, so that the storage cost is greatly saved, and the access utilization rate of the data is ensured to themaximum extent.

Description

technical field

[0001] The invention relates to the technical field of data update, in particular to a cold and hot data storage method and device, and electronic equipment. Background technique

[0002] With the development and continuous operation of the business, the business system of the enterprise often generates a large amount of data, which is stored in the database for users to access according to different business needs. At present, in order to cope with high-frequency data access, most enterprises use large-scale storage clusters with high real-time performance (such as MySQL, Cassandra, and MongoDB) to store data. However, due to the large amount of data, the access performance of the database is degraded. If more databases are built to match the increasing data size, the storage cost will be greatly increased. Contents of the invention

[0003] In order to solve the problem of high data storage cost in the related art, the present invention provides a cold a...
