Problems solved by technology

[0007] However, the problem with the above-mentioned solution 1 is that if a certain storage server becomes abnormal and becomes very slow, the read requests for the data copies on this storage server will be affected, which will greatly affect the delay of read requests;
[0008] The problem with solution 2 is that, assuming that the number of data copies is N, for a client read request, the proxy server will send N requests to the storage server cluster, which increases the read request pressure by N times, greatly Increased pressure on storage servers

Abstract

The invention discloses a data reading method, device and system of a distributed table system, electronic equipment and a computer readable storage medium. The method comprises the following steps: receiving a reading request sent by a client; responding to the reading request to obtain a storage server list where the data copy corresponding to the reading request is located; sending a reading request to a first storage server in the storage server list; and starting a delay task while sending the reading request so as to send the reading request to a second storage server in the storage server list after a predetermined delay time. According to the invention, the influence on the read request delay of the whole cluster due to the slow speed of a certain storage server can be avoided.

Description

technical field [0001] The present invention relates to the technical field of distributed table systems, in particular to a data reading method, device and system of a distributed table system. Background technique [0002] With the rapid increase of Internet data scale, distributed storage system came into being. Distributed storage systems can be classified into distributed file systems, distributed object storage, block storage, and distributed table systems according to their functions. In a distributed table system, in order to ensure data security and tolerate bad disks and server downtime, multiple copies are generally used to store data. In the multiple copies of the distributed table system, one of the data copies is the master and the other data copies are the slaves. The distributed table system relies on the master-slave relationship of the data copies to maintain the consistency of the data between the copies. [0003] Usually, when reading data, first the da...
