+| Read\_from\_Head | For new discovered files on start \(without a database offset/position\), read the content from the head of the file, not tail. Be cautious: enabling this setting may cause duplicate logs on restarts when using `DB`, as Fluent Bit will ignore offsets. Therefore, it is recommended to keep this disabled in production environments.                                                                                                                                                                                                                                                                                                                                                                       | False |
