Functions

func CalculateOriginalIndex

func CalculateOriginalIndex(childIdx int, toCache *bitarray.BitSet) int

CalculateOriginalIndex computes the original index of a sub-task.

func InitializeExternalResources

func InitializeExternalResources(ctx context.Context, tCtx core.TaskExecutionContext, state *State,
	generateSubTaskID func(core.TaskExecutionContext, int) string) ([]*core.ExternalResource, error)

InitializeExternalResources constructs an ExternalResource array where each element describes the initial state of the subtask. This involves labeling all cached subtasks as successful with a cache hit and initializing others to undefined state.

func InvertBitSet

func InvertBitSet(input *bitarray.BitSet, limit uint) *bitarray.BitSet

func MapArrayStateToPluginPhase

func MapArrayStateToPluginPhase(_ context.Context, state *State, logLinks []*idlCore.TaskLog, externalResources []*core.ExternalResource) (core.PhaseInfo, error)

Any state of the plugin needs to map to a core.PhaseInfo (which in turn will map to Admin events) so that the rest of the Flyte platform can understand what's happening. That is, each possible state that our plugin state machine returns should map to a unique (core.Phase, core.PhaseInfo.version). Info fields will always be nil, because we're going to send log links individually. This simplifies our state handling as we don't have to keep an ever growing list of log links (our batch jobs can be 5000 sub-tasks, keeping all the log links takes up a lot of space).

func NewPhasesCompactArray

func NewPhasesCompactArray(count uint) bitarray.CompactArray

func ToArrayJob

func ToArrayJob(structObj *structpb.Struct, taskTypeVersion int32) (*idlPlugins.ArrayJob, error)

Types

type Phase

type Phase uint8
const (
	PhaseStart Phase = iota
	PhasePreLaunch
	PhaseLaunch
	PhaseWaitingForResources
	PhaseCheckingSubTaskExecutions
	PhaseAssembleFinalOutput
	PhaseWriteToDiscovery
	PhaseWriteToDiscoveryThenFail
	PhaseSuccess
	PhaseAssembleFinalError
	PhaseRetryableFailure
	PhasePermanentFailure
)

func PhaseString

func PhaseString(s string) (Phase, error)

PhaseString retrieves an enum value from the enum constants string name. Throws an error if the param is not part of the enum.

func PhaseValues

func PhaseValues() []Phase

PhaseValues returns all values of the enum

func SummaryToPhase

func SummaryToPhase(ctx context.Context, minSuccesses int64, summary arraystatus.ArraySummary) Phase

func (Phase) IsAPhase

func (i Phase) IsAPhase() bool

IsAPhase returns "true" if the value is listed in the enum definition. "false" otherwise

func (Phase) String

func (i Phase) String() string
