Hi Howard, Your timing is…. Interesting given we are focusing on getting 3.0 shipped and are in the final throws of that.
Let's revisit this in May or June once the dust has settled from 3.0, any immediate bug fixes we might need, and give people a little bit of time to unwind after the crunch. -ash > On 14 Apr 2025, at 16:22, Howard Yoo <howard...@gmail.com> wrote: > > Hi Airflow community members, > > Apache Airflow has been moving steadily from conventional statsd based > telemetry into OpenTelemetry (opentelemetry.io), which has gained > popularity and support for the last few years.
