Functions

func Advance 

func Advance(s *Schedule) error

Advance advances the schedule to the next traffic fraction. A schedule can only be advanced if it's ready. See the Ready method.

func ChangeTimes 

func ChangeTimes(t *TargetFn, start time.Time) []time.Time

ChangeTimes returns the set of times at which the target function changes, assuming the target function is started at the provided time.

func Done 

func Done(s *Schedule) bool

Done returns whether the schedule has been fully applied.

func Fraction 

func Fraction(s *Schedule) float32

Fraction returns the current traffic fraction.

func IncrementAppliedDuration 

func IncrementAppliedDuration(s *Schedule, d time.Duration)

IncrementAppliedDuration increases the duration the current traffic fraction has been applied.

func Length 

func Length(t *TargetFn) time.Duration

Length returns the total length of the TargetFn.

func Ready 

func Ready(s *Schedule) bool

Ready returns whether the schedule is ready to be advanced. A schedule is ready to be advanced if the current traffic fraction has been applied for its specified duration.

Example usage: 

if Ready(schedule) {
    if err := Advance(schedule); err != nil {
        ...
    }
}

func Remaining 

func Remaining(s *Schedule) time.Duration

Remaining returns the remaining duration the current traffic fraction should be applied for.

func TargetFraction 

func TargetFraction(t *TargetFn, d time.Duration) float32

TargetFraction returns the target fraction at the given duration after a target function has started to be applied, assuming no delays.

type TargetFn 

type TargetFn struct {
	Fractions []*FractionSpec `protobuf:"bytes,1,rep,name=fractions,proto3" json:"fractions,omitempty"`
	// contains filtered or unexported fields
}

TargetFn is a target function that controls the traffic rollout for a given application version inside a deployment location (e.g., a cloud region).

Each entry F_i in TargetFn stores a traffic fraction that should be assigned to the application version, as well as the duration of that traffic assignment.

Traffic assignment starts with entry F_0. Once the traffic fraction in F_i has been applied for longer than the duration specified in F_i, the traffic fraction in the entry F_(i+1) is applied. This process continues until all entries in the array have been exhausted, at which point the traffic fraction of 1.0 is applied and the application version is considered "installed".

Note that the traffic fraction is considered "applied" the moment it is successfully assigned to the application version. Failed fraction assignments don't count toward the fraction duration; instead, the earlier fraction remains applied. This means that some traffic fractions may be applied for significantly longer than the specified duration (e.g., cluster becomes unreachable); the only guarantee we provide is that a given fraction will never be applied for less than a specified duration.

TrafficAllocation contains a traffic allocation. It is the finest granularity in terms of traffic assignment.

TrafficAssignment contains a traffic assignment keyed by hostname.

func CascadeTraffic 

func CascadeTraffic(targets []*CascadeTarget) (*TrafficAssignment, error)

CascadeTraffic assigns traffic to a set of targets. For every host, a traffic fraction of 1.0 is cascaded across the versions that export the host.

For example, imagine we version v1, v2, and v3 that export hosts [a, c], [a, b, c], and [b, c] respectively. v1, v2, and v3 have desired traffic fractions of 0.5, 0.4, and 0.4. We cascade traffic between the listeners as follows: 

v1 (0.5) | v2 (0.4) | v3 (0.4)
---------+----------+---------
 a (0.6) |  a (0.4) |
         |  b (0.6) |  b (0.4)
 c (0.2) |  c (0.4) |  c (0.4)

func MergeTrafficAssignments 

func MergeTrafficAssignments(components []*TrafficAssignment) *TrafficAssignment

MergeTrafficAssignments merges the traffic assignments for each hostname across multiple components.

A component can be an application or a location (e.g., a cloud region).

At a high-level, for a given hostname H it does the following:

  • all of H's traffic allocations in each component are appended together to form the set of allocations for H in the merged set.

  • if H appears in N components, the traffic allocations for H in each component are normalized by a factor of 1/N.

The above algorithm has the property that if the traffic allocations for H were adding up to 1.0 in the individual components, they will add up to 1.0 in the merged set as well.
