=============== Virtual Tables

Virtual tables expose system-level information in the familiar CQL or Alternator interfaces. Virtual tables are not backed by physical storage (sstables) and generate their content on-the-fly when queried.

ScyllaDB supports:

• Virtual tables for retrieving system-level information, such as the cluster status, version-related information, etc. The range of information they can expose partially overlaps with the information you can obtain via :doc:nodetool </operating-scylla/nodetool> (unlike nodetool, virtual tables permit remote access over CQL).
• The virtual table for querying and updating configuration over CQL (the system.config table).

See Virtual tables in the system keyspace <https://github.com/scylladb/scylla/blob/master/docs/dev/system_keyspace.md#virtual-tables-in-the-system-keyspace>_ for the list of available virtual tables.
