Starts the VoltDB database process. The voltdb command can also collect log files for analyzing possible system errors (see Section 7.3, “Collecting the Log Files” for details).

The voltdb command runs locally and does not require a running database.

Issues administrative commands to a running VoltDB database. You can use voltadmin to save and restore snapshots, pause and resume admin mode, and to shutdown the database, among other tasks.

The voltadmin command can be run remotely, performs cluster-wide operations and requires a running database to connect to.

Lets you issue SQL queries and invoke stored procedures interactively. The sqlcmd command is handy for testing database access without having to write a client application.

The sqlcmd command can be run remotely and requires a running database to connect to.

These utilities load data from external sources into an existing VoltDB database. They let you load data from CSV or text-based data files, JDBC data sources, or Apache Kafka streams. These commands can be run remotely and require a running database to connect to.

Converts native snapshot files to csv or tabbed text files. The snapshotconvert command is useful when exporting a snapshot in native format to text files for import into another data utility. (This utility is provided for legacy purposes. It is now possible to write snapshots directly to CSV format without post-processing, which is the recommended approach.)

The snapshotconvert command runs locally and does not require a running database.

Verifies that a set of native snapshot files are complete and valid.

The snapshotverify command runs locally and does not require a running database.
