The invention relates to the technical field of
cloud computing and distributed storage, and discloses a distributed
metadata management method and storage
system based on
cloud computing, and the method comprises the following steps: S1, collecting the
access frequency of a plurality of
metadata objects in a set time period; s2, performing weighting
processing on the
access frequency, and constructing access
heat distribution under multiple time scales; s3, obtaining the available
cache capacity of a plurality of cache nodes, and constructing cache resource
weight distribution; s4, assessing the access cost and migration cost between each
metadata object and each cache node; and S5, generating a scheduling strategy between the metadata object and the cache node based on a preset optimization target, wherein the optimization target is access cost minimization. According to the method, a heat, resource and cost joint modeling mechanism is constructed, and
optimal scheduling and feedback
adaptive control are combined, so that accurate decision, dynamic adjustment and migration cost
controllability of copy deployment are realized, and the performance and stability of distributed
metadata management are effectively improved.
