.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"\.
.SH RETURN VALUE
On success, an object is returned, containing:
.RS
.IP \[bu]

\fBgeneration\fR (u64, optional): The number of times this has been updated
.IP \[bu]
\fBhex\fR (hex, optional): The hex data which has been added to the datastore
.IP \[bu]
\fBstring\fR (string, optional): The data as a string, if it's valid utf-8
.RE
