Subject [jira] [Commented] (IGNITE-9355) Document new system views (nodes, node attributes, baseline nodes, node metrics)
Date Tue, 13 Nov 2018 17:40:00 GMT

Denis Magda commented on IGNITE-9355:
-------------------------------------

[~Artem Budnikov], thanks for applying the changes. I just came across ODBC/JDBC session management
page and know think it would be better if that and the views page would be under a single
section like "Management and Monitoring". What do you think?

> 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)
>  # System view NODE_METRICS - node metrics. Columns - see \{{org.apache.ignite.internal.processors.query.h2.sys.view.SqlSystemViewNodeMetrics}}
class
>  # Explain limitations: views cannot be joined with user tables; it is not allowed to
create other objects (tables, indexes) in "IGNITE" schema.
