             Summary: StatsdSink supports TCP mode
                 Key: SPARK-48298
                 URL: https://issues.apache.org/jira/browse/SPARK-48298
             Project: Spark
          Issue Type: New Feature
          Components: Spark Core
    Affects Versions: 4.0.0
            Reporter: Eric Yang


Currently, the StatsdSink in Spark supports UDP mode only, which is the default 
mode of StatsD. However, in real production environments, we often find that a 
more reliable transmission of metrics is needed to avoid metrics lose in 
high-traffic systems.

 

TCP mode is already supported by Statsd: 
[https://github.com/statsd/statsd/blob/master/docs/server.md]

Prometheus' statsd_exporter: [https://github.com/prometheus/statsd_exporter] 

and also many other Statsd-based metrics proxy/receiver.
