Types

type IndexProvider added in v0.34.0 

type IndexProvider interface {
	// NextIndex provides an index for the supplied MutateContext.
	NextIndex(ctx boltz.MutateContext) (uint64, error)

	// CurrentIndex provides the current index
	CurrentIndex() uint64
}

type InstantStrategy 

type InstantStrategy struct {
	InstantStrategyOptions

	*common.RouterDataModel
	// contains filtered or unexported fields
}

InstantStrategy assumes that on connect, the router requires and instant and full set of API Sessions. Send individual create, update, delete events for sessions after synchronization.

This strategy uses a series of queues and workers to managed synchronization state. The order of events is as follows:

  1. An edge router connects to the controller, triggering RouterConnected()
  2. A RouterSender is created encapsulating the Edge Router, Router, and Sync State
  3. The RouterSender is queued on the routerConnectedQueue channel which buffers up to options.MaxQueuedRouterConnects
  4. The routerConnectedQueue is read and the edge server hello is sent
  5. The controller waits for a client hello to be received via ReceiveClientHello message
  6. The client hello is used to identity the RouterSender associated with the client and is queued on the receivedClientHelloQueue channel which buffers up to options.MaxQueuedClientHellos
  7. A startSynchronizeWorker will pick up the RouterSender from the receivedClientHelloQueue and being to send data to the edge router via the RouterSender
