Abstract

The invention relates to a data storage method, a data retrieval method, electronic equipment and a storage medium. The data storage method comprises the steps of receiving a first data storage request, wherein the first data storage request is used for storing to-be-stored data in a first storage engine; if it is determined that the to-be-stored data has a routing key based on the first data storage request, obtaining a routing key value of the to-be-stored data; determining a partition of a first storage engine corresponding to the to-be-stored data according to the routing key value of theto-be-stored data; and storing the to-be-stored data in a partition of a first storage engine corresponding to the to-be-stored data. According to the method and the device, the data with the same routing key value can be stored in the same partition of the first storage engine, so that when data retrieval is carried out through the first storage engine, the data volume needing to be retrieved canbe greatly reduced, the retrieval efficiency of the first storage engine is improved, and calculation resources can be saved.

Description

technical field [0001] The present disclosure relates to the field of computer technology, and in particular to a data storage and retrieval method, electronic equipment and a storage medium. Background technique [0002] Table Store (TableStore) is a high-performance, low-cost, easy-to-expand and fully managed semi-structured data storage platform based on shared storage, which supports efficient computing and analysis of Internet and Internet of Things data. Table Store is a distributed multi-model database that supports multiple data models (including wide rows, messages, time series, space-time, graphs, and documents) to meet the needs of different application scenarios. [0003] Distributed databases need to partition data to take advantage of distributed computing power. The partition of distributed database is usually divided into range (Range) partition and hash (Hash) partition. Among them, the range partition uses the range of the column value as the division con...
