The handler function has this signature.

Sample handler:
```go
    handler :=  func(ctx context.Context, payload []byte, in <-chan []byte, out chan<- []byte) *RemoteErr {
        fmt.Println("Got request with initial payload", p, "from", GetCaller(ctx context.Context))
        fmt.Println("Subroute:", GetSubroute(ctx))
        for {
            select {

// Batch represents an ordered batch
type Batch[I any] struct {
	items  []I
	limit  uint32
	store  Store[I]
	quitCh chan struct{}

	sync.Mutex
}

// BatchConfig represents the batch config
type BatchConfig[I any] struct {
	Limit         uint32
	Store         Store[I]
	CommitTimeout time.Duration
	Log           logger

	es := &expiryState{
