Hi all, I went through the bookkeeper configuration file to see if there are any settings we should change their default values for most of the installations.
Here I would like to raise a discussion about two settings: - `journalRemoveFromPageCache`: this settings is false. but it should be enabled by default, because journal pages are okay to be removed from page cache after they are fsynced to disks. That is what Twitter/Yahoo is using on production. - `fileInfoCacheInitialCapacity`: this setting is related to `openFileLimit`. `openFileLimit` is 20000 by default. so change this value to 1/4 of openFileLimit, giving a good balance between initial capacity and the limit and also avoid resizing cache too many times if it eventually hits the limit. Here the proposed change: https://github.com/apache/bookkeeper/pull/1294 - Sijie
