This commit modifies the edge update index migration to avoid repetitive calls to Cursor.First(). Instead, we construct a set of all edge update keys to remove, and then do a second pass to remove each from the bucket. Additional log messages are included to notify users on progress, as some have reported long migration times.
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
