Improvements

• Enabled the following instrumentation by default
  • Java Executor Service (#295)
    • Caveat: you still need to manually toggle it in your custom instrumentation.
      ((TraceScope) scope).setAsyncPropagation(true);
    • Some frameworks (servlets and jms message listeners) have this flag toggled automatically (#316)
• Dynamically rename services via configuration (#314)
  • Useful for making databases have distinct names across different services.
  • Configure mapping as follows:
    • System property: dd.service.mapping=mysql:my-service-db,cassandra:my-service-cassandra
    • Environment variable: DD_SERVICE_MAPPING=mysql:my-service-db,cassandra:my-service-cassandra
• Automatically set service name based on servlet context (war file name) if not already configured or configured, but empty. (#320)
• Improved instrumentation for AWS client: (#299)
  • This includes a change to the resource name.
• Automatically detect non-Datadog @Trace annotations (#311)
  • List of annotations can be replaced (or disabled with an empty list) using the following setting:
    • System property: dd.trace.annotations=com.some.Trace;io.other.Trace
    • Environment variable: DD_TRACE_ANNOTATIONS=com.some.Trace;io.other.Trace
• Configure additional methods to be traced without code change: (#311)
  • System property: dd.trace.methods=package.ClassName[method1,method2,...];AnonymousClass$1[call]
  • Environment variable: DD_TRACE_METHODS=package.ClassName[method1,method2];AnonymousClass$1[call]
• Automatically set a configured header value as a span tag (#317)
  • System property: dd.trace.header.tags=CASE-insensitive-Header:my-tag-name,User-ID:userId
  • Environment variable: DD_TRACE_HEADER_TAGS=CASE-insensitive-Header:my-tag-name,User-ID:userId
• Improve naming for @Trace generated spans on methods inside anonymous classes: now includes more class name. (#303)
• Upgraded to Byte Buddy 1.8.8 (#293)
• Remove guava dependency for dd-trace-ot (#307)

New Instrumentation (disabled by default)

• Hystrix (#306)
  • System property: dd.integration.hystrix.enabled=true
  • Environment variable: DD_INTEGRATION_HYSTRIX_ENABLED=true

• Minor Kafka instrumentation change to reduce chance of breaking (#297)
• Prevent nested JDBC spans (#302)
