Functions

func Cancel added in v1.7.5

func Cancel(ctx context.Context, pipelineRcName string, etcdClient *etcd.Client,
	etcdPrefix string, jobID string, dataFilter []string) error

Cancel cancels a set of datums running on workers. pipelineRcName is the name of the pipeline's RC and can be gotten with ppsutil.PipelineRcName.

func Conns added in v1.7.5

func Conns(ctx context.Context, pipelineRcName string, etcdClient *etcd.Client, etcdPrefix string) ([]*grpc.ClientConn, error)

Conns returns a slice of connections to worker servers. pipelineRcName is the name of the pipeline's RC and can be gotten with ppsutil.PipelineRcName. You can also pass "" for pipelineRcName to get all clients for all workers.

func HashDatum

func HashDatum(pipelineName string, pipelineSalt string, data []*Input) string

HashDatum computes and returns the hash of datum + pipeline, with a pipeline-specific prefix.

func HashDatum15

func HashDatum15(pipelineInfo *pps.PipelineInfo, data []*Input) (string, error)

HashDatum15 computes and returns the hash of datum + pipeline for version <= 1.5.0, with a pipeline-specific prefix.

func MatchDatum

func MatchDatum(filter []string, data []*pps.InputFile) bool

MatchDatum checks if a datum matches a filter. To match each string in filter must correspond match at least 1 datum's Path or Hash. Order of filter and data is irrelevant.

func RegisterWorkerServer

func RegisterWorkerServer(s *grpc.Server, srv WorkerServer)

func Status added in v1.7.5

func Status(ctx context.Context, pipelineRcName string, etcdClient *etcd.Client, etcdPrefix string) ([]*pps.WorkerStatus, error)

Status returns the statuses of workers referenced by pipelineRcName. pipelineRcName is the name of the pipeline's RC and can be gotten with ppsutil.PipelineRcName. You can also pass "" for pipelineRcName to get all clients for all workers.
