type CacheBackend ¶

type CacheBackend struct {
	as.Backend
	http.Handler
	// contains filtered or unexported fields
}

CacheBackend is both an accountserver Backend and a http.Handler that implements the replicated invalidation RPCs.

CacheBackend implements a simple in-memory cache of user objects (not resources yet), in order to reduce the database and processing load in presence of a heavily read-oriented workload. The cache is very simple, and any update to a user or its resources cause us to go back to the database backend.

User objects are kept in memory for a short while and periodically cleaned up. Memory usage thus depends on the load and is difficult to estimate in advance.
