This commit splits FetchPaymentStatus and UpdatePaymentStatus, such that they each invoke helper methods that can be composed into different db txns. This enables us to improve performance on send/receive, as we can remove the exclusive lock from the control tower, and allow concurrent calls to utilize Batch more effectively.
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
