Embodiment Construction
[0039] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments, but the following embodiments in no way limit the present invention.
[0040] Such as Figure 1-5 As shown, the NoSQL-based massive aviation logistics small file storage structure includes a data cache area, a data active area and a data permanent area; wherein the data active area is located between the data buffer area and the data permanent area;
[0041] The data cache area is located in the node memory of each data node, and the Redis memory database is used as a cache, and a self-built cluster is built between the Redis databases of each data node, which is used to store the index of small files and the cache data prefetch mechanism document;
[0042] The data active area belongs to the data storage area of the data node of HDFS, and is used to store file data in the active area;
[0043] The data permanent area belongs to the data stor...
