Enable kotlin_coroutine integration by default #8848

mcculls · 2025-05-19T16:50:26Z

Motivation

The Kotlin coroutines integration is now considered stable enough to enable by default.

Doing so avoids an extra configuration step for users of Kotlin coroutines.

If necessary the integration can be disabled with this JVM option:

-Ddd.integration.kotlin_coroutine.enabled=false

or by setting this environment variable:

DD_INTEGRATION_KOTLIN_COROUTINE_ENABLED=false

Note: using @Trace or DD_TRACE_METHODS on functions using Kotlin Coroutines currently result in separate spans for the function, before and after suspend points.

tested 1.49.0 with coroutines enabled

Looks like this issue holds true
#7755

traces don't correlate when above coroutines 1.8.1. On 1.8.1 it works fine.
