database.yml的所有可能键都是什么

Question

我刚刚发现文件中reconnect: true可以配置选项database.yml.还有哪些其他可能的配置选项？所有选项都有完整的参考吗？

已知的关键示例:

default: &default
  adapter: mysql2
  encoding: utf8
  pool: 5
  username: foo
  password: bar
  reconnect: true
  socket: /var/sock/thing.sock

development:
  <<: *default
  database: app_development

我不认为有任何地方只是列出它们但我检查了ActiveRecord的ConnectionAdapaters.请记住,选项会更改您使用的数据库,但这是在MySQL连接适配器中列出的.
