fbdump

fbdump

fbdump is a tool to dump a bunch of Firebase Auth user records. Firebase provides firebase-tools that can export firebase users. However the tool is not suitable to export a lot of users about than 1 million. Because,

• Can not retry if aborted before completed
• Can output only one large file that is breakable by abort
• Will crash after export about tens of millions of users by stack overflow of recursive call.

fbdump keeps dumping state for retry when aborted and can start again from aborted point. Additionally, the tool splits exported user records to multiple files for avoiding to break a file by abort.
