Constants

View Source 
const Shards = 100

Shards is the sharding level for the Invocations table. Column Invocations.ShardId is a value in range [0, Shards).

Variables

This section is empty.

Functions

func CurrentMaxShard 

func CurrentMaxShard(ctx context.Context) (int, error)

CurrentMaxShard reads the highest shard id in the Invocations table. This may differ from the constant above when it has changed recently.

func InclusionKey 

func InclusionKey(including, included ID) spanner.Key

InclusionKey returns a spanner key for an Inclusion row.

func QueryRealms 

func QueryRealms(ctx context.Context, ids IDSet) (realms map[ID]string, err error)

QueryRealms returns the invocations' realms where available from the Invocations table. Makes a single RPC.

func Read 

func Read(ctx context.Context, id ID) (*pb.Invocation, error)

Read reads one invocation from Spanner. If the invocation does not exist, the returned error is annotated with NotFound GRPC code.

func ReadBatch 

func ReadBatch(ctx context.Context, ids IDSet) (map[ID]*pb.Invocation, error)

ReadBatch reads multiple invocations from Spanner. If any of them are not found, returns an error.

func ReadColumns 

func ReadColumns(ctx context.Context, id ID, ptrMap map[string]any) error

ReadColumns reads the specified columns from an invocation Spanner row. If the invocation does not exist, the returned error is annotated with NotFound GRPC code. For ptrMap see ReadRow comment in span/util.go.

func ReadRealm 

func ReadRealm(ctx context.Context, id ID) (string, error)

ReadRealm returns the invocation's realm.

func ReadRealms 

func ReadRealms(ctx context.Context, ids IDSet) (realms map[ID]string, err error)

ReadRealms returns the invocations' realms. Returns a NotFound error if unable to get the realm for any of the requested invocations. Makes a single RPC.

func ReadState 

func ReadState(ctx context.Context, id ID) (pb.Invocation_State, error)

ReadState returns the invocation's state.

func ReadStateBatch 

func ReadStateBatch(ctx context.Context, ids IDSet) (map[ID]pb.Invocation_State, error)

ReadStateBatch reads the states of multiple invocations.

func ReadSubmitted 

func ReadSubmitted(ctx context.Context, id ID) (bool, error)

ReadSubmitted returns the invocation's submitted status.

func TokenToMap 

func TokenToMap(token string, dest map[string]any, keys ...string) error

TokenToMap parses a page token to a map. The first component of the token is expected to be an invocation ID. Convenient to initialize Spanner statement parameters. Expects the token to be either empty or have len(keys) components. If the token is empty, sets map values to "".

Types

type ExportInfo 

type ExportInfo struct {
	// Whether the invocation is in FINALIZED or FINALIZING state.
	IsInvocationFinal bool
	// The realm of the invocation.
	Realm string
	// IsSourcesSpecFinalEffective whether the source information is immutable.
	// This is true if either IsSourceSpecFinal is set on the invocation, or
	// the invocation is in FINALIZING or FINALIZED state.
	IsSourceSpecFinalEffective bool
	// IsInheritingSources contains whether the invocation is inheriting sources
	// from its parent (including) invocation.
	IsInheritingSources bool
	// Sources are the concrete sources specific on the invocation (if any).
	Sources *pb.Sources
}

ExportInfo captures information pertinent to exporting an invocation and propogating export roots.

func ReadExportInfo 

func ReadExportInfo(ctx context.Context, invID ID) (ExportInfo, error)

ReadExportInfo reads information pertinent to exporting an invocation.

type FinalizedNotificationInfo 

type FinalizedNotificationInfo struct {
	// The realm of the invocation.
	Realm string
	// Whether this invocation is a root of the invocation graph for export purposes.
	IsExportRoot bool
	// When the invocation was created.
	CreateTime *timestamppb.Timestamp
}

FinalizedNotificationInfo captures information for sending an invocation finalized notification.

func ReadFinalizedNotificationInfo 

func ReadFinalizedNotificationInfo(ctx context.Context, invID ID) (FinalizedNotificationInfo, error)

ReadFinalizedNotificationInfo reads information for sending an invocation finalized notification.

type IDSet 

type IDSet map[ID]struct{}

IDSet is an unordered set of invocation ids.

func MustParseNames 

func MustParseNames(names []string) IDSet
