Package proxycache registers the "proxycache" blobserver storage type, which uses a provided blobserver as a cache for a second origin blobserver.
If the provided maxCacheBytes is unspecified, the default is 512MB.
Example config:
"/cache/": {
"handler": "storage-proxycache",
"handlerArgs": {
"origin": "/cloud-blobs/",
"cache": "/local-ssd/",
"maxCacheBytes": 536870912
}
},

type Storage
type Storage struct {
// contains filtered or unexported fields
}
Storage implements the "proxycache" blob storage.
func New
func New(maxBytes int64, cache, origin blobserver.Storage) *Storage
New returns a proxycache blob storage that reads from cache, then origin, populating cache as needed, up to a total of maxBytes.
