README

We will replace redhub epoll model in future with https://github.com/pawelgaczynski/gain

seeking to make this the fastest redis server in golang in the world.

REDHUB

RedHub

GoDoc FOSSA Status

High-performance Redis-Server multi-threaded framework, based on RawEpoll model.

  • Ultra high performance
  • Fully multi-threaded support
  • Low CPU resource consumption
  • Compatible with redis protocol
  • Create a Redis compatible server with RawEpoll model in Go

Installing

go get -u github.com/IceFireDB/redhub

Example

Here is a simple framework usage example,support the following redis commands:

  • SET key value
  • GET key
  • DEL key
  • PING
  • QUIT

You can run this example in terminal:

go run example/server.go

Functions

func ListendAndServe 

func ListendAndServe(addr string, options Options, rh *redHub) error

func NewRedex 

func NewRedex(
	onOpened func(c *Conn) (out []byte, action Action),
	onClosed func(c *Conn, err error) (action Action),
	handler func(cmd resp.Command, out []byte) ([]byte, Action),
) *redHub

Types

type Action 

type Action int
const (
	// None indicates that no action should occur following an event.
	None Action = iota

	// Close closes the connection.
	Close

	// Shutdown shutdowns the server.
	Shutdown
)

type Conn 

type Conn struct {
	gnet.Conn
}

type Options 

type Options struct {
	// Multicore indicates whether the server will be effectively created with multi-cores, if so,
	// then you must take care with synchronizing memory between all event callbacks, otherwise,
	// it will run the server with single thread. The number of threads in the server will be automatically
	// assigned to the value of logical CPUs usable by the current process.
	Multicore bool

	// LockOSThread is used to determine whether each I/O event-loop is associated to an OS thread, it is useful when you
	// need some kind of mechanisms like thread local storage, or invoke certain C libraries (such as graphics lib: GLib)
	// that require thread-level manipulation via cgo, or want all I/O event-loops to actually run in parallel for a
	// potential higher performance.
	LockOSThread bool

	// ReadBufferCap is the maximum number of bytes that can be read from the client when the readable event comes.
	// The default value is 64KB, it can be reduced to avoid starving subsequent client connections.
	//
	// Note that ReadBufferCap will be always converted to the least power of two integer value greater than
	// or equal to its real amount.
	ReadBufferCap int

	// LB represents the load-balancing algorithm used when assigning new connections.
	LB gnet.LoadBalancing

	// NumEventLoop is set up to start the given number of event-loop goroutine.
	// Note: Setting up NumEventLoop will override Multicore.
	NumEventLoop int

	// ReusePort indicates whether to set up the SO_REUSEPORT socket option.
	ReusePort bool

	// Ticker indicates whether the ticker has been set up.
	Ticker bool

	// TCPKeepAlive sets up a duration for (SO_KEEPALIVE) socket option.
	TCPKeepAlive time.Duration

	// TCPNoDelay controls whether the operating system should delay
	// packet transmission in hopes of sending fewer packets (Nagle's algorithm).
	//
	// The default is true (no delay), meaning that data is sent
	// as soon as possible after a Write.
	TCPNoDelay gnet.TCPSocketOpt

	// SocketRecvBuffer sets the maximum socket receive buffer in bytes.
	SocketRecvBuffer int

	// SocketSendBuffer sets the maximum socket send buffer in bytes.
	SocketSendBuffer int

	// ICodec encodes and decodes TCP stream.
	Codec gnet.ICodec
