Functions ¶
func Compare ¶
func Compare(a, b ContextKey) int
Compare returns an integer comparing two strings lexicographically. The result will be 0 if a==b, -1 if a < b, and +1 if a > b.
Types ¶
type ContextKey ¶
type ContextKey [byteSize]byte
ContextKey is a non-cryptographic hash that allows to aggregate metrics from a same context together.
This implementation has been designed to remove all heap allocations from the intake to reduce GC pressure on high volumes.
It uses the 128bit murmur3 hash, that is already successfully used on other products. 128bit is probably overkill for avoiding collisions, but it's better to err on the safe side, as we do not have a collision mitigation mechanism.
func Generate ¶
func Generate(name, hostname string, tags []string) ContextKey
Generate returns the ContextKey hash for the given parameters. The tags array is sorted in place to avoid heap allocations.
func Parse ¶
func Parse(src string) (ContextKey, error)
Parse returns a ContextKey instanciated with the value decoded as hexa
func (ContextKey) IsZero ¶
func (k ContextKey) IsZero() bool
IsZero returns true if the key is at zero value
func (ContextKey) String ¶
func (k ContextKey) String() string
String returns the hexadecimal representation of the key
