Prometheus v2.17.0-rc.1 Release Notes
Release Date: 2020-03-16 // about 4 years ago-
🚀 This release implements isolation in TSDB. API queries and recording rules are
👀 guaranteed to only see full scrapes and full recording rules. This comes with a
certain overhead in resource usage. Depending on the situation, there might be
🚤 some increase in memory usage, CPU usage, or query latency.- 👍 [FEATURE] TSDB: Support isolation #6841
