Functions ¶
func InitContext ¶
InitContext adds a cache metrics struct to the context to allow keeping track of cache calls during a request
func RecordCacheDelete ¶
RecordCacheDelete records a deletion from the cache
func RecordCacheHit ¶
RecordCacheHit records a cache hit
func RecordCacheMiss ¶
RecordCacheMiss records a cache miss
func RecordCacheStore ¶
RecordCacheStore records store data in the cache
func RecordMultiGet ¶
RecordMultiGet records getting multiple objects from the cache
Types ¶
type CacheMetrics ¶
type CacheMetrics struct {
Calls int
Hits int
Misses int
Deletions int
GetLatencies time.Duration
StoreLatencies time.Duration
DeletionLatencies time.Duration
}
CacheMetrics keeps track of cache calls during a request We don't take a lock to access these fields as we perform read only once per request at the end, effectively single threaded
func GetMetrics ¶
func GetMetrics(ctx context.Context) (*CacheMetrics, error)
GetMetrics returns the cache metrics structure from the context, errors out if it is not there.
func (*CacheMetrics) GetTotalDuration ¶
func (m *CacheMetrics) GetTotalDuration() time.Duration
GetTotalDuration returns the sum of the time spend calling the cache
func (*CacheMetrics) HadCalls ¶
func (m *CacheMetrics) HadCalls() bool
HadCalls returns true if there were any cache calls
