.SH NAME
|
|
lightning-datastore - Command for storing (plugin) data
|
|
.SH SYNOPSIS
|
|
|
|
\fBdatastore\fR \fIkey\fR [\fIstring\fR] [\fIhex\fR] [\fImode\fR] [\fIgeneration\fR]
|
|
|
|
.SH DESCRIPTION
|
|
|
|
The \fBdatastore\fR RPC command allows plugins to store data in the
|
|
c-lightning database, for later retrieval\.
|
|
|
|
|
|
\fIkey\fR is an array of values (though a single value is treated as a
|
|
one-element array), to form a heirarchy\. Using the first element of
|
|
the key as the plugin name (e\.g\. \fB[ "summary" ]\fR) is recommended\.
|
|
A key can either have children or a value, never both: parents are
|
|
created and removed automatically\.
|
|
|
|
|
|
\fImode\fR is one of "must-create" (default, fails it it already exists),
|
|
"must-replace" (fails it it doesn't already exist),
|
|
"create-or-replace" (never fails), "must-append" (must already exist,
|
|
append this to what's already there) or "create-or-append" (append if
|
|
anything is there, otherwise create)\.
|
|
|
|
|
|
\fIgeneration\fR, if specified, means that the update will fail if the
|
|
previously-existing data is not exactly that generation\. This allows
|
|
for simple atomicity\. This is only legal with \fImode\fR "must-replace"
|
|
or "must-append"\.
