Functions

func ReadMessage 

func ReadMessage(buf *[]byte, r ByteReadReader, msg proto.Message) error

Read a message from io.ByteReader by first reading a varint size, and then reading and decoding the message object. If buf is not big enough a new buffer will be allocated to replace buf.

func WriteMessage 

func WriteMessage(msg proto.Message, w io.Writer) error

Write the message to the io.Writer with a varint size header.

Types

type BeginBatch 

type BeginBatch struct {
	Name   string            `protobuf:"bytes,1,opt,name=name" json:"name,omitempty"`
	Group  string            `protobuf:"bytes,2,opt,name=group" json:"group,omitempty"`
	Tags   map[string]string `` /* 128-byte string literal not displayed */
	Size   int64             `protobuf:"varint,4,opt,name=size" json:"size,omitempty"`
	ByName bool              `protobuf:"varint,5,opt,name=byName" json:"byName,omitempty"`
}

Indicates the beginning of a batch. All subsequent points should be considered part of the batch until EndBatch arrives. This includes grouping. Batches of differing groups may not be interleaved.

All the meta data but tmax is provided, since tmax may not be known at the beginning of a batch.

Size is the number of points in the batch. If size is 0 then the batch has an undetermined size.

type Server added in v0.13.0 

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

Server provides an implementation for the core communication with UDFs. The Server provides only a partial implementation of udf.Interface as it is expected that setup and teardown will be necessary to create a Server. As such the Open and Close methods are not implemented.

Once a Server is created and started the owner can send points or batches to the UDF by writing them to the PointIn or BatchIn channels respectively, and according to the type of UDF created.

The Server may be Aborted at anytime for various reasons. It is the owner's responsibility via the abortCallback to stop writing to the *In channels since no more selects on the channels will be performed.

Calling Stop on the Server should only be done once the owner has stopped writing to the *In channel, at which point the remaining data will be processed and the UDF will be allowed to clean up.

Callling Info returns information about available options the UDF has.

Calling Init is required to process data. The behavior is undefined if you send points/batches to the Server without calling Init.

func NewServer added in v0.13.0

	in ByteReadReader,
	out io.WriteCloser,
