Method Details

start

public void start()

Specified by:

start in interface Emitter

emit

public void emit(Event event)

Description copied from interface: Emitter

Emit an event. This method must not throw exceptions or block. If an implementation receives too many events and internal queues fill up, it should drop events rather than blocking or consuming excessive memory. If an implementation receives input it considers to be invalid, or has an internal problem, it should deal with that by logging a warning rather than throwing an exception. Implementations that log warnings should consider throttling warnings to avoid excessive logs, since a busy Druid cluster can emit a high volume of metric events.
