Remove the ignite node from cluster.

[takumi <bl...@a01.itscom.net>]

I am trying to create a highly scalability system.
When the system becomes low load, I scale-in system.
At this time, I want to remove the node correctly from ignite cluster.
In order to transfer the data and backup of that node to another node
automatically, how should I do?

I think that at first, you should stop Ignite node using Ignition.stop and
then remove the node from Baseline topology using
https://apacheignite.readme.io/docs/cluster-activation#section--remove-nodes-from-the-topology-
to invoke rebalancing. Also, you need to remove nodes one by one.

Thank you for reply.

If I remove ignite instance from the cluster, just kill Java process which
is the ignite instance？
I want to know the correct way to shutdown.

In addition, if scaled-in is occured, when should I update the baseline
topology?
I want to know when must I updates baseline topology and when it re-balance.

Hi,

I think the safest way to do it is to remove nodes on by one from the
cluster and wait till rebalance finished after each node(of course, if you
have backups). But you should remember, that in case of huge amount of
data, rebalance could take some time, which could be significant when you
want to scale-out again.
