This commit modifies the nodeWithDist struct to use a route.Vertex instead of a *channeldb.LightningNode. This change, coupled with the new ForEachNodeChannel function, allows the findPath Djikstra's algorithm to cut down on database lookups since we no longer need to call the FetchOtherNode function.
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
