In this commit, we eliminate an extraneous copy in the `QueryPayments` method. Before this commit, we would copy each payment from the initial FetchPayments call into a new slice. However, pointers to payments are return from `FetchPayments`, so we can just maintain that same reference rather than copying again when we want to limit our response.
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
