zipkin.reporter

Class AsyncReporter<S>

java.lang.Object

zipkin.reporter.AsyncReporter<S>

Type Parameters:

S - type of the span, usually Span

All Implemented Interfaces:

Closeable, Flushable, AutoCloseable, zipkin.Component, Reporter<S>

public abstract class AsyncReporter<S>
extends Object
implements Reporter<S>, Flushable, zipkin.Component

As spans are reported, they are encoded and added to a pending queue. The task of sending spans happens on a separate thread which calls flush(). By doing so, callers are protected from latency or exceptions possible when exporting spans out of process.

Spans are bundled into messages based on size in bytes or a timeout, whichever happens first.
