Recover / restore database after lost power?

[martinboehm]

This is by design, you will have to delete the database folder and start again.

By default, Blockbook performs the initial import in bulk import mode, which for performance reasons does not store all the data immediately to the database. The database is therefore in an inconsistent state and does not survive hard reset of the server.

If you are in an environment, where power outages may be frequent, you can run Blockbook with parameter -workers=1, which disables the bulk import mode. As a consequence, the initial import is about twice as slow but the DB should be consistent even in the case of hard reset and also the memory requirements are a lot lower.
