Types ¶
type RedisDirectory ¶
type RedisDirectory struct {
Inner identity.Directory
ErrTTL time.Duration
HitTTL time.Duration
// contains filtered or unexported fields
}
Uses redis as a cache for identity lookups.
Includes an in-process LRU cache as well (provided by the redis client library), for hot key (identities).
func NewRedisDirectory ¶
func NewRedisDirectory(inner identity.Directory, redisURL string, hitTTL, errTTL time.Duration, lruSize int) (*RedisDirectory, error)
Creates a new caching `identity.Directory` wrapper around an existing directory, using Redis and in-process LRU for caching.
`redisURL` contains all the redis connection config options. `hitTTL` and `errTTL` define how long successful and errored identity metadata should be cached (respectively). errTTL is expected to be shorted than hitTTL. `lruSize` is the size of the in-process cache, for each of the handle and identity caches. 10000 is a reasonable default.
func (*RedisDirectory) Lookup ¶
func (d *RedisDirectory) Lookup(ctx context.Context, a syntax.AtIdentifier) (*identity.Identity, error)
func (*RedisDirectory) LookupHandle ¶
func (*RedisDirectory) Purge ¶
func (d *RedisDirectory) Purge(ctx context.Context, a syntax.AtIdentifier) error
