Abstract

The invention discloses a distributed data storage method, a server and a readable storage medium. The method comprises the following steps: selecting first N data fragments from a plurality of existing data fragments of a distributed storage system as sliding windows; When the new data is written in, judging whether the new data is compared with the data in the sliding window or not; If yes, abandoning writing of new data, and executing a sliding window adjustment operation at the same time to write the next new data according to the adjusted sliding window; Wherein the sliding window adjustment operation comprises the steps of obtaining a subordinate data fragment which has repeated data with new data which is abandoned to be written in from a sliding window, and dynamically adjusting the area size of the sliding window according to the subordinate data fragment so as to enable the subordinate data fragment to further comprise a data fragment. Therefore, before the new data is written next time, the data in the sliding window is adjusted into the data with higher local repeatability probability with the new data written next time according to the fragment where the repeated datais located, and the write-in query efficiency can be improved.

Description

technical field [0001] The invention relates to the field of data storage, in particular to a distributed data storage method, a server and a readable storage medium. Background technique [0002] With the development and deepening of information technology, the total amount of data in the network has shown explosive growth, and more and more data in the storage system requires a large amount of storage space to store relevant data in Internet services. Since the storage space of the distributed storage system can be expanded infinitely, it has been widely used in storing Internet business data. [0003] In a distributed storage system, when storing data with local repetitive characteristics in time, in order to prevent duplication of written data and waste of storage capacity, it is necessary to perform data processing on the data to be written in the process of data writing. Duplicate checking and then writing, but the efficiency is too low when using existing technology ...
