Bowen Li created FLINK-8553:
-------------------------------

             Summary: switch flink-metrics-datadog to async mode
                 Key: FLINK-8553
                 URL: https://issues.apache.org/jira/browse/FLINK-8553
             Project: Flink
          Issue Type: Improvement
          Components: Metrics
    Affects Versions: 1.4.0
            Reporter: Bowen Li
            Assignee: Bowen Li
             Fix For: 1.5.0


Even though currently flink-metrics-datadog is designed as `fire-and-forget`, it's still using sync calls which may block or slow down core. Need to switch it to async mode.
