@prombot prombot released this Mar 24, 2020

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.
