This commit partially reverts bf27d05a. To avoid creating multiple database transactions during a single path finding operation, we create an explicit transaction when the cached graph is instantiated. We cache the source node to avoid needing to look that up for every path finding session. The database transaction will be nil in case of the in-memory graph.
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
