const DefaultProducerID = "propeller"

DefaultProducerID is used in older versions of propeller which hard code this producer id. See https://github.com/nebulaclouds/nebulapropeller/blob/eaf084934de5d630cd4c11aae15ecae780cc787e/pkg/controller/nodes/task/transformer.go#L114

const EqualExpression = "eq"

const ExecutionIDLength = 20

const ExecutionStringFormat = "a%s"

const MaxResponseStatusBytes = 32000

Variables

var ResourceTypeToEntity = map[core.ResourceType]Entity{
	core.ResourceType_LAUNCH_PLAN: LaunchPlan,
	core.ResourceType_TASK:        Task,
	core.ResourceType_WORKFLOW:    Workflow,
}

ResourceTypeToEntity maps a resource type to an entity suitable for use with Database filters

var RuntimeTypeKey = contextutils.Key("runtime_type")

var RuntimeVersionKey = contextutils.Key("runtime_version")

Types

type ArtifactType

type ArtifactType int

const (
	ArtifactTypeUndefined ArtifactType = iota
	ArtifactTypeI                      // inputs
	ArtifactTypeO                      // outputs
	ArtifactTypeD                      // deck
)

The suffixes in these constants are used to match against the tail end of the nebula url, to keep the nebula url simpler

func ArtifactTypeString

func ArtifactTypeValues() []ArtifactType

ArtifactTypeValues returns all values of the enum

func (ArtifactType) IsAArtifactType

func (i ArtifactType) IsAArtifactType() bool

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

func (ArtifactType) String
