Class TraceProcessingDisruptor

java.lang.Object

datadog.trace.common.writer.ddagent.TraceProcessingDisruptor

All Implemented Interfaces:

Closeable, AutoCloseable

public class TraceProcessingDisruptor
extends Object

Disruptor that takes completed traces and applies processing to them. Upon completion, the serialized trace is published to BatchWritingDisruptor.

publishing to the buffer will not block the calling thread, but instead will return false if the buffer is full. This is to avoid impacting an application thread.
