Can I let Ignite to do rebalance at a particular time?
When Ignite doing rebalance, sometimes it will affect other normal
processing.
Can I let Ignite only to do rebalance at a particular time if necessary,
such as at 0:00 every day?

what is the difference between
"CacheConfiguration.setRebalanceMode(CacheRebalanceMode.NONE)" and
"CacheConfiguration.setRebalanceDelay(-1)"?
I think both of them need to start rebalance manually by calling
IgniteCache.rebalance().
BTW, At the particular time, Can I know whether it need to do rebalance or
not? Because I just want to do rebalance if necessary.

Hi,
Totally agree wit that. And it should be possible to start re-balancing
from client node too.

I don't see the difference on how to start re-balancing: from Ignite API
or console, result will be the same.

Cross-posting to dev.
Guys,
Is there any reason for such implementation? Does it ever makes sense to
trigger rebalancing on only one node?
I think rebalance() method should broadcast automatically and do the job on
all nodes. Just in case, we can also add localRebalance() method. This will
be more intuitive and also more consistent with other APIs, like
loadCache/localLoadCache.

Thank you for your guidance.
I will try calling IgniteCache.rebalance() via compute broadcast task.
But I think it is more convenient to start rebalancing manually from
management console, is it right?

Hi,
Sorry, I confused you. For proper rebalance work you need to set rebalance
mode to SYNC or ASYNC, rebalance delay to -1 and call
IgniteCache.rebalance() on each node that participate in cache. The better
way to do this is via compute broadcast task.
Rebalance mode NONE disables rebalancing at all, that's why it doesn't work
for you.
Thanks!
-Dmitry.

I have tried CacheConfiguration.setRebalanceMode(CacheRebalanceMode.NONE),
and called IgniteCache.rebalance() later, but the data did not rebalance
between the nodes.
Is there any problem with my usage?

Hi,
Yes, you can set for caches that you want
CacheConfiguration.setRebalanceMode(CacheRebalanceMode.NONE), and call
IgniteCache.rebalance() when you need. To schedule rebalancing you may refer
IgniteScheduler [1].
