func (*Context) SetTopologyRegistry

func (c *Context) SetTopologyRegistry(r TopologyRegistry)

type ContextGlobalVariables

type ContextGlobalVariables struct {
	// Logger is used to write log messages.
	Logger *logrus.Logger

	// LogDestination is a writer to which logs are written.
	LogDestination io.WriteCloser

	// Topologies is a registry which manages topologies to support multi

type TopologyRegistry

type TopologyRegistry interface {
	// Register registers a new topology. If the registry already has a
	// topology having the same name, this method fails and returns
	// os.ErrExist.
	Register(name string, tb *bql.TopologyBuilder) error
