Overview

\n

Upon completion of data source creation, to accelerate the access, users can create cache pre-load rules to bind the data source to bucket directories or their subdirectories, caching the data into the instance data source for accelerated access.

\n

When the instance capacity is full, cache data follows the least recently used (LRU) release strategy. To prevent the release of actively accessed cached data during pre-loading, create cache release rules to proactively release cached data from specified directories that no longer require accelerated access, thereby ensuring available instance capacity.

\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n
Rule typeType overview
Cache pre-loadUpon creation of a cache pre-load rule, users can trigger a cache pre-load task to cache data from the bound bucket directory or its subdirectories of the data source into the RapidFS instance
Cache releaseUpon creation of a cache release rule, it is possible to trigger a cache release task to remove cached data from the bound bucket directory or its subdirectories in the data source

RapidFSh instanceRequiredDrop-down options for RapidFS instances already created within the same region
Data sourceRequiredDropdown options, selected RapidFS instance and created data source
Trigger methodRequiredCache pre-load/cache release: Cache pre-load is used to load data under specified directories in the data source in advance, while cache release actively removes cached data from specified directories
PathOptionalThe relative path of the data source directory, defaulted as the directory of data source
