<@U04BDJK3LMV> 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.

I see. <@U01HWQ1RTC2> Do we have the steps to configure otel collector sampling documented somewhere

<@U04BDJK3LMV> 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 should also consider setting up s3 as cold storage <https://signoz.io/docs/userguide/retention-period/#configuring-cold-storage---amazon-s3>

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/>

Thanks for the Support <@U02CL7HGYDD> ^ <@U01HWQ1RTC2>; Will have a look into these.
