To further separate the channel graph from the channel state, we refactor the AddrsForNode method to use the graphs's public methods instead of directly accessing any buckets. This makes sure that we can have the channel state cached with just its buckets while not using a kvdb level cache for the graph. At the same time we refactor the graph's test to also be less dependent upon the channel state DB.
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
