Increase the default number of compression jobs and prevent a "thundering herd" scenario #588

Closed sumerman closed 1 year ago

sumerman commented 1 year ago

Description

It seems like 1 metric compression job is almost never enough and our benchmarks show that 3 should be sufficient for thousands of metrics with 30min chunks.

In addition, this PR addresses a thundering herd scenario when reconfiguring maintenance jobs.
