---------------------------------------

             Summary: Document 3 new system views (nodes, node attributes, baseline nodes)
                 Key: IGNITE-9355
                 URL: https://issues.apache.org/jira/browse/IGNITE-9355
             Project: Ignite
          Issue Type: Task
          Components: documentation, sql
            Reporter: Vladimir Ozerov
             Fix For: 2.7


We need to document three new SQL system views.
 # Explain users that new system SQL schema appeared, named "IGNITE", where all views are
stored
 # System view NODES - list of current nodes in topology. Columns: ID, CONSISTENT_ID, VERSION,
IS_LOCAL, IS_CLIENT, IS_DAEMON, NODE_ORDER, ADDRESSES, HOSTNAMES
 # System view NODE_ATTRIBUTES - attributes for all nodes. Columns: NODE_ID, NAME, VALUE
 # System view BASELINE_NODES - list of baseline topology nodes. Columns: CONSISTENT_ID, ONLINE
(whether node is up and running at the moment)
 # Explain limitations: views cannot be joined with user tables; it is not allowed to create
other objects (tables, indexes) in "IGNITE" schema.
