The present invention relates to the technical field of distributed storage, and discloses a distributed data storage method, a retrieval method, a system and a readable storage medium. A target node receives the target data sent by a sensor, and searches in the first index table corresponding to the target node whether Include the target index item corresponding to K. If the target index item is included in the first index table, V is additionally stored in the target index item, and the target data source corresponding to the target data is generated, and the target data source and V are associated and stored. ; In the case that the target index is not included in the first index table, an index item K is created in the first index table, and the target data source and V are associated and stored in the index item K, which can solve the problem of existing distributed storage methods The cost is high, and it cannot flexibly meet the needs of different operations.
Description
technical field [0001] The present invention relates to the technical field of distributed storage, in particular to a distributed data storage method, a retrieval method, a system and a readable storage medium. Background technique [0002] With the continuous integration of informatization and industrialization, in the production process, more and more sensors are deployed to perceive the production process data. These production data are of great significance for judging the production status and delivery cycle. Therefore, the storage of these data can usually be pre-stored by a nearby storage device, and then the pre-stored data is processed and transmitted to the background. It can be seen that these sensory data play an important role in the traceability of the production process. Since the Internet of Things technology has changed the thinking of the traditional Internet, connecting things to things, and automatically sensing data by deploying sensors, storage is gen...
