Expand description

Writes changed_version to the on-disk database after the format is changed. (Or a new database is created.)

The database path is based on its kind, changed_version.major, and network.


This should only be called:

  • after each format upgrade is complete,
  • when creating a new database, or
  • when an older Zebra version opens a newer database.


This must only be called while RocksDB has an open database for config. Otherwise, multiple Zebra processes could write the version at the same time, corrupting the file.
