New Relic data retention minimums by telemetry type and subscription edition

Goal: Determine the minimum retention period for metrics, events, logs, and traces under a given New Relic subscription edition, and whether reducing ingest volume with drop filters also reduces retention-related charges for a low-traffic workload.

Retention is configurable per telemetry type, but the lowest allowable retention varies by data type and edition. It is uncertain whether ingest, retention, and seat billing update independently, and whether a shortened retention window appears in cost projections immediately or only after older data ages out. Drop filters may lower billable ingest while retention charges remain tied to the configured window.

What is the shortest retention period for each telemetry type across subscription editions?

Does a retention change update projected costs immediately, or only after data ages out?

Can drop filters reduce retention charges without changing the retention configuration?
