["Fil Karnicki (Jira)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/FLINK-22390?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17505354#comment-17505354 ] 

Fil Karnicki commented on FLINK-22390:
--------------------------------------

I guess this should be renamed to Support for OpenTelemetry.

_>> The OpenTracing project is {*}deprecated{*}. Please use [OpenTelemetry|https://opentelemetry.io/], which provides [backwards compatibility|https://github.com/open-telemetry/opentelemetry-specification/blob/main/specification/compatibility/opentracing.md] with OpenTracing._

>                 URL: https://issues.apache.org/jira/browse/FLINK-22390
>             Project: Flink
>          Issue Type: New Feature
>          Components: Stateful Functions
>            Reporter: Konstantin Knauf
>            Priority: Minor
>
> OpenTracing for Stateful Functions could help particularly with topology analysis and performance analysis. 
> A few questions come to mind: 
> * would we instrument both the functions as well as the runtime, or only the runtime? 
> * what tracing implementation to use?
