I see tail based sampling is work in progress, is upfront sampling supported? Looking for ways to limit ingested traces.

@Vignesh Rajkumar Yes upfront sampling should be possible. Just curious, what are your main use cases for limiting ingested traces

We have a 500GB EBS storage configured for Signoz instance. The space ran out in matter of hours. We'd like to trace 1 of every 10 request the instrumented application gets.

@Vignesh Rajkumar you can use https://github.com/open-telemetry/opentelemetry-collector-contrib/tree/main/processor/probabilisticsamplerprocessor at k8s-infra-chart. After that, all the data received and APM metrics will be sampled by that ratio
you can also disable
TIMESTAMP_SORT_FEATURE
and
DURATION_SORT_FEATURE
if you don't use them. It should help in reducing size to almost half. https://signoz.io/docs/operate/feature-flags/
