-------------------------------
Assignee: Aleksandr Iushmanov
> FLIP-553 [Metrics] Robust OTel gRPC metric exporter
> ---------------------------------------------------
>
> Key: FLINK-38603
> URL: https://issues.apache.org/jira/browse/FLINK-38603
> Project: Flink
> Issue Type: New Feature
> Reporter: Aleksandr Iushmanov
> Assignee: Aleksandr Iushmanov
> Priority: Minor
>
> Jobs with large number of tasks and operator can result in significant
> payload size. Open Telemetry exporter gRPC calls can be rejected due to too
> large payload leading to loss of exported metric data in production
> environments. Existing implementation presents the following limitations:
> # While OTel exporter allows to enable gZip compression for requests, it is
> not available in Flink Configuration.
> # All metric data is exported in a single gRPC call, with no pagination
> which impacts complex enough jobs.
> # Metric attributes can be unexpectedly large, for example task_name
> attribute can contain hundreds of operator names inside and be present in
> multiple metrics having a significant impact on overall payload.
