Database
--------
c-lightning state is persisted in `lightning-dir`. It is a sqlite database
stored in the `lightningd.sqlite3` file, typically under `~/.lightning`. You can
run queries against this file like so:
$ sqlite3 ~/.lightning/lightningd.sqlite3 "SELECT HEX(prev_out_tx), prev_out_index, status FROM outputs"
Or you can launch into the sqlite3 repl and check things out from there:
$ sqlite3 ~/.lightning/lightningd.sqlite3
SQLite version 3.21.0 2017-10-24 18:55:49
Enter ".help" for usage hints.
sqlite> .tables
channel_configs invoices peers vars
channel_htlcs outputs shachain_known version
channels payments shachains
sqlite> .schema outputs
...
Some data is stored as raw bytes, use `HEX(column)` to pretty print these.
Make sure that clightning is not running when you query the database, as some
queries may lock the database and cause crashes.
