Abstract

The embodiment of the invention discloses a data processing method and device, electronic equipment, a system and a storage medium, and the data processing method comprises the steps: creating a query task, and determining whether the query task contains split key information or not; when the query task contains the split key information, sending the query task to a first server, so that the first server executes the query task according to a routing rule corresponding to the split key information; and when the query task does not contain the split key information, sending the query task to the second server, so that the second server executes the query task according to a reverse index, and the reverse index is established by the second server according to data synchronized from the first server. In the embodiment of the invention, when the query task does not contain the split key information, the reverse index in the second server can be utilized to assist the query, so that full-table scanning is avoided, the query speed is increased, and the query efficiency is improved.

Description

technical field [0001] Embodiments of the present invention relate to computer technology, and in particular, to a data processing method, device, electronic equipment, system, and storage medium. Background technique [0002] In a distributed storage system, in order to deal with the problem of excessive data volume, data is usually stored in sub-databases and tables according to the split key. In the process of realizing the present invention, the inventor found that, for the data stored in the distributed storage system, when querying, if the query request carries the split key, the fast query can be realized according to the split key, and if the query request If there is no split key in the table, a full table scan is required, which is time-consuming and the query efficiency is relatively low. Contents of the invention [0003] Embodiments of the present invention provide a data processing method, device, electronic equipment, system, and storage medium, which can i...
