Functions

func CreateConsumerGroups

func CreateConsumerGroups(ctx context.Context, client *redis.Client, opts *cli.RedisStreamsOptions) error

func Dynamic

func Dynamic(opts *cli.Options) error

Dynamic starts up a new GRPC client connected to the dProxy service and receives a stream of outbound replay messages which are then written to the message bus.

func NewClient

func NewClient(opts *cli.Options) (*redis.Client, error)

func NewStreamsClient

func NewStreamsClient(opts *cli.Options) (*redis.Client, error)

func Read

func Read(opts *cli.Options, md *desc.MessageDescriptor) error

func Relay

func Relay(opts *cli.Options, relayCh chan interface{}, shutdownCtx context.Context) (relay.IRelayBackend, error)

Relay sets up a new RedisStreams relayer

func Write

func Write(opts *cli.Options, md *desc.MessageDescriptor) error

Write is the entry point function for performing write operations in RedisStreams.

This is where we verify that the passed args and flags combo makes sense, attempt to establish a connection, parse protobuf before finally attempting to perform the write.

Types

type RedisStreams

type RedisStreams struct {
	Options *cli.Options
	Client  *redis.Client
	MsgDesc *desc.MessageDescriptor
	Context context.Context
	// contains filtered or unexported fields
}

func (*RedisStreams) Read

func (r *RedisStreams) Read() error

func (*RedisStreams) Write

func (r *RedisStreams) Write(value []byte) error

type Relayer

type Relayer struct {
	Client  *redis.Client
	Options *cli.Options
	RelayCh chan interface{}

	Looper      *director.FreeLooper
	ShutdownCtx context.Context
	// contains filtered or unexported fields
}

func (*Relayer) Relay

func (r *Relayer) Relay() error

Relay reads messages from RedisStreams and sends them to RelayCh which is then read by relay.Run()
