Constants

const (
	Execution          = "e"
	LaunchPlan         = "l"
	NodeExecution      = "ne"
	NodeExecutionEvent = "nee"
	Task               = "t"
	TaskExecution      = "te"
	Workflow           = "w"
)

const AllowedExecutionIDStartCharStr = "abcdefghijklmnopqrstuvwxyz"

In kubernetes, resource names must comply with this regex: '[a-z]([-a-z0-9]*[a-z0-9])?'

const AllowedExecutionIDStr = "abcdefghijklmnopqrstuvwxyz1234567890"

const EqualExpression = "eq"

const ExecutionIDLength = 10

Variables

var AllowedExecutionIDChars = []rune(AllowedExecutionIDStr)

var AllowedExecutionIDStartChars = []rune(AllowedExecutionIDStartCharStr)

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")
