Class SegmentContextExecutors

java.lang.Object

com.amazonaws.xray.contexts.SegmentContextExecutors

public final class SegmentContextExecutors
extends java.lang.Object

Executors that will mount a segment before running a command. When switching threads, for example when instrumenting an asynchronous application, it is recommended to use one of these Executors to make sure callbacks have the trace segment available.

 DynamoDbAsyncClient client = DynamoDbAsyncClient.create();

 client.getItem(request).thenComposeAsync(response -> {
     // If we did not provide the segment context executor, this request would not be traced correctly.
     return client.getItem(request2);
 }, SegmentContextExecutors.newSegmentContextExecutor()); *
