In case the channeldb package is used as a library in external tools, it can be useful to allow read-only access to a DB. This allows such a tool to access a DB even if not all migrations were executed, which can be useful for recovery purposes. To make it possible to even start the DB with a read-only backend, we need to disable the automatic migration step.
channeldb
The channeldb implements the persistent storage engine for lnd and
generically a data storage layer for the required state within the Lightning
Network. The backing storage engine is
boltdb, an embedded pure-go key-value store
based off of LMDB.
The package implements an object-oriented storage model with queries and mutations flowing through a particular object instance rather than the database itself. The storage implemented by the objects includes: open channels, past commitment revocation states, the channel graph which includes authenticated node and channel announcements, outgoing payments, and invoices
