Class: ActiveRecord::ConnectionAdapters::ConnectionPool::Reaper

Overview

Every #frequency seconds, the reaper will call #reap and #flush on #pool. A reaper instantiated with a zero frequency will never reap the connection pool.

Configure the frequency by setting reaping_frequency in your database yaml file (default 60 seconds).
