Functions

func EnsureNoNestedPipelines

func EnsureNoNestedPipelines(pipelinePaths []string) error

Types

type Issue

type Issue struct {
	Task        *pipeline.Asset
	Description string
	Context     []string
}

func EnsureAthenaSQLTypeTasksHasDatabaseAndS3FilePath

func EnsureAthenaSQLTypeTasksHasDatabaseAndS3FilePath(p *pipeline.Pipeline) ([]*Issue, error)

func EnsureDependencyExists

func EnsureDependencyExists(p *pipeline.Pipeline) ([]*Issue, error)

func EnsureMaterializationValuesAreValid

func EnsureMaterializationValuesAreValid(p *pipeline.Pipeline) ([]*Issue, error)

func EnsureOnlyAcceptedTaskTypesAreThere

func EnsureOnlyAcceptedTaskTypesAreThere(p *pipeline.Pipeline) ([]*Issue, error)

func EnsurePipelineHasNoCycles

func EnsurePipelineHasNoCycles(p *pipeline.Pipeline) ([]*Issue, error)

EnsurePipelineHasNoCycles ensures that the pipeline is a DAG, and contains no cycles. Since the pipelines are directed graphs, strongly connected components mean cycles, therefore they would be considered invalid for our pipelines. Strong connectivity wouldn't work for tasks that depend on themselves, therefore there's a specific check for that.

func EnsurePipelineNameIsValid

func EnsurePipelineNameIsValid(pipeline *pipeline.Pipeline) ([]*Issue, error)

func EnsurePipelineScheduleIsValidCron

func EnsurePipelineScheduleIsValidCron(p *pipeline.Pipeline) ([]*Issue, error)

func EnsureSlackFieldInPipelineIsValid

func EnsureSlackFieldInPipelineIsValid(p *pipeline.Pipeline) ([]*Issue, error)

func EnsureSnowflakeSensorHasQueryParameter

func EnsureSnowflakeSensorHasQueryParameter(p *pipeline.Pipeline) ([]*Issue, error)
