Restoring from a SQLite dump file
rqlite supports loading a cluster directly from a SQLite dump file. This is a fast and efficient manner to bootstrap a system from an existing SQLite database. An example restore is shown below. Please note that this functionality is currently experimental.
Example
The following example shows a trivial database being generated by sqlite3, dumped to a file, and then loaded into an rqlite node listening on localhost.
~ $ sqlite3 restore.sqlite
SQLite version 3.14.1 2016-08-11 18:53:32
Enter ".help" for usage hints.
sqlite> CREATE TABLE foo (id integer not null primary key, name text);
sqlite> INSERT INTO "foo" VALUES(1,'fiona');
sqlite>
~ $ echo '.dump' | sqlite3 restore.sqlite > restore.dump
~ $ curl -XPOST localhost:4001/db/load --data-binary @restore.dump
~ $ echo '.dump' | sqlite3 restore.sqlite > restore.dump
Let's connect to the node, and check that the data has been loaded correctly.
$ rqlite
127.0.0.1:4001> SELECT * FROM foo
