    Description

      To minimize the impact of query sampling on user workloads, writes to the config.sampledQueries and config.sampleQueriesDiff collections should be deprioritized the same way that writes by the TTL monitor and range deleter are. Here is an example how the deprioritizing is done for the range deleter.
