Subject [jira] [Commented] (IGNITE-9355) Document new system views (nodes, node attributes, baseline nodes, node metrics)
Date Fri, 12 Oct 2018 11:53:00 GMT

    [ https://issues.apache.org/jira/browse/IGNITE-9355?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16647812#comment-16647812

Artem Budnikov commented on IGNITE-9355:
----------------------------------------

[~pgarg]  

I added this table as a plain markdown snippet instead of using the built-in readme.io table,
the reason being I generated the table semi-automatically to save myself some time. Apparently,
readme.io renders markdown tables differently. I've corrected this now by adding custom css
in the appearance section of the dashboard. Now it looks consistently with other tables.

> 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.
