-----------------------------------
Summary: Document manual cluster activation feature
Key: IGNITE-6682
URL: https://issues.apache.org/jira/browse/IGNITE-6682
Project: Ignite
Issue Type: Bug
Security Level: Public (Viewable by anyone)
Reporter: Denis Magda
Assignee: Prachi Garg
Once Ignite persistence is enabled, the cluster has to be activated manually
before any operation can be processed by it. That's needed to ensure that all
the nodes that have data on disk have joined the cluster after a restart and
that the topology is considered to be stable.
Some details can be found in this discussion:
* Usage section of this doc [1]. Look for a paragraph that starts with _"Next,
when Ignite sees that the persistence is enabled it moves the cluster from
active to inactive state making sure that applications cannot​ modify the data
until allowed."_
*

Document the manual cluster activation on a dedicated page [2] at least
considering the following:
* Overview. Why it's required? Move the paragraph from [1] and expand if
required.
* Show an exception that happens if you try to execute a SQL or key-value query
or run a computation against an activated cluster.
* Explain how to activate the cluster with:
* From command line with control.sh script.
* From web console.
* From source code with {{Ignite.activate()}} method.
* Add a callout that the automatic cluster activation is to be added in the
future. You may refer to this discussion [3].
