[GitHub] janl opened a new pull request #1203: Compaction Daemon & db-per-user

janl opened a new pull request #1203: Compaction Daemon & db-per-user
URL: https://github.com/apache/couchdb/pull/1203
 
 
   This PR addresses a number of issues with the Compaction Daemon when run under a db-per-user scenario:
   
   1. with many database and/or many view groups in one or more databases, checking whether a file should be compacted can create significant CPU load. This PR both:
      1. spaces the `check_interval` from 5 minutes to 60 minutes,
      2. and introduces a 3 second `snooze_period` between compacting any two files.
   2. when a view index is opened or closed, we send a `notice` level log line. In this scenario, this balloons the log file for no good benefit. The logs are not demoted to `debug`.
   
   - [x] code works
   - [x] no tests
   - [x] documented in `default.ini`
