Constants

const RawEventField = "rawEvent"

Regardless of DB implementation for Registry, it requires the ETL spec to use RawEventField as the key for storing each spec.

Types

type Config

type Config struct {

	// Specifies which mode to use (in-memory, custom, etc)
	StorageMode admin.RegStorageMode

	// RegSpec is only used when StorageMode is set to admin.RegStorageCustom and contains
	// the spec registration spec to use. It is currently only needed by clients to Registry
	// during initialization of StreamRegistry.
	RegSpec []byte

	// Specifies which environment string to match against stream specs using the OpsPerEnv
	// part of the spec. If empty it is disregarded.
	Env string
}

type StreamRegistry

type StreamRegistry struct {
	// contains filtered or unexported fields
}

StreamRegistry implements both the Registry and the Executor interfaces so that it can serve both as the bootstrap/CRUD Registry service for the supervisor, and as the continuous spec registration service via GEIST REST API, ingesting specs in an ETL Stream with arbitrary Sinks/Loaders.

func NewStreamRegistry

func NewStreamRegistry(config Config, executor igeist.Executor, notifyChan entity.NotifyChan, logging bool) *StreamRegistry

func (*StreamRegistry) Delete

func (r *StreamRegistry) Delete(ctx context.Context, id string) error

func (*StreamRegistry) Exists

func (r *StreamRegistry) Exists(id string) bool

func (*StreamRegistry) ExistsWithSameOrHigherVersion

func (r *StreamRegistry) ExistsWithSameOrHigherVersion(specBytes []byte) (bool, error)

func (*StreamRegistry) Fetch

func (r *StreamRegistry) Fetch(ctx context.Context) error

func (*StreamRegistry) Get

func (r *StreamRegistry) Get(ctx context.Context, id string) (igeist.Spec, error)

func (*StreamRegistry) GetAll

func (r *StreamRegistry) GetAll(ctx context.Context) (map[string]igeist.Spec, error)

func (*StreamRegistry) Metrics

func (r *StreamRegistry) Metrics() entity.Metrics

func (*StreamRegistry) ProcessEvent

func (r *StreamRegistry) ProcessEvent(ctx context.Context, events []entity.Event) entity.EventProcessingResult

func (*StreamRegistry) Put

func (r *StreamRegistry) Put(ctx context.Context, id string, spec igeist.Spec) (err error)

The StreamRegistry implementation of Registry.Put() only caches the spec in-memory, since the actual persistence of specs are done with its Stream Executor implementation inside ProcessEvent(), which in turn relies on the assigned Loader to store the spec. It is currently only used internally from StreamRegistry's ProcessEvent function as part of Supervisor managed updated of new specs, thus no mutex needed on specs map.

func (*StreamRegistry) SetAdminStream

func (r *StreamRegistry) SetAdminStream(stream igeist.Stream)

func (*StreamRegistry) Shutdown

func (*StreamRegistry) StreamId

func (r *StreamRegistry) StreamId() string

func (*StreamRegistry) Validate

func (r *StreamRegistry) Validate(specBytes []byte) (igeist.Spec, error)
