The invention discloses a
client origin information associative
perception based
metadata pre-acquisition method and
system. The method comprises: collecting origin information log records in a kernel space of a
client, and transmitting the records to a
user space from the kernel space; selecting part of the collected origin information log records at the
client as associative training data of
metadata, and computing an associative
score between every two
metadata to obtain an original strong associative
list; when the client initiates a file access request and metadata of a file are not in a local metadata cache of the client, pre-acquiring multiple strongly associative metadata from the strong associative
list of the client, downloading corresponding metadata from a
metadata server, and updating the local metadata cache of the client; and according to added origin information log records, regularly updating the strong associative
list of the metadata. According to the method and the
system, the metadata
cache hit rate of the client is increased, and the frequency of access to the
metadata server is reduced, so that the performance of the
metadata server is improved.
