This commit implements an easy optimization by using bolt db’s Batch method when writing payment details to disk. The AddPaymnent method can be concurrently called by thousands of grouting due to the way the payment dispatch pipeline is architected. With this commit, we shave of a significant amount of running time when users are sending thousands of payments a second as what would’ve been thousands of writes can now be coalesced into one or two writes!
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
