Types

type Buffer 

type Buffer interface {
	// Add adds message to the buffer and returns a reference counted message.
	Add(m Message) (*RefCountedMessage, error)

	// Init initializes the buffer.
	Init()

	// Close stops the buffer from accepting new requests immediately.
	// If the CloseType is WaitForConsumption, then it will block until all the messages have been consumed.
	// If the CloseType is DropEverything, then it will simply drop all the messages buffered and return.
	Close(ct CloseType)
}

Buffer buffers all the messages in the producer.

type CloseType 

type CloseType int

CloseType decides how the producer should be closed. 

const (
	// WaitForConsumption blocks the close call until all the messages have been consumed.
	WaitForConsumption CloseType = iota
	// DropEverything will close the producer and drop all the messages that have not been consumed.
	DropEverything
)

type FilterFunc 

type FilterFunc func(m Message) bool

FilterFunc can filter message.

type FinalizeReason 

type FinalizeReason int

FinalizeReason defines the reason why the message is being finalized by Producer. 

const (
	// Consumed means the message has been fully consumed.
	Consumed FinalizeReason = iota

	// Dropped means the message has been dropped.
	Dropped
)

type Message 

type Message interface {
	// Shard returns the shard of the message.
	Shard() uint32

	// Bytes returns the bytes of the message.
	Bytes() []byte

	// Size returns the size of the bytes of the message.
	Size() int

	// Finalize will be called by producer to indicate the end of its lifecycle.
	Finalize(FinalizeReason)
}

Message contains the data that will be produced by the producer. It should only be finalized by the producer.
