Alexey,
Thank you for the response.

It is even better, there is nothing to do with expiration.
Ivan,
Sorry for a delay in reply. Yes, I was thinking about the same use-case,
and in this particular case an unexpected load on a 3rd-party database
manifests itself. I am not sure how expiration relates to the partition
ownership - once a partition moves to a renting state, all entries are
eager
As a reminder - we already have a ticket for a deprecation of
rebalanceDelay as well [1]

Ivan,
My opinion the ASYNC rebalancing is a best approach for off-loading 3-d
party store, and it provides consistency.
+1 for deprecation of NONE in the next release - ignore NONE and use ASYNC
instead
For those who require absence of rebalancing for some reason still be
possible to use rebalance
Alexey,
Thank you for explanation. I feel that I miss a couple bits to
understand the picture fully. I am thinking about a case which I tend
to call a Memcached use-case. There is a cache over underlying storage
with read-through and expiration and without any rebalancing at all.

Ivan,
In my understanding this mode does not work at all even in the presence of
ForceKeysRequest which is now supposed to fetch values from peers in case
of a miss. In this mode we 1) move partitions to OWNING state
unconditionally, and 2) choose an arbitrary OWNING node for force keys
request. T
+1 for deprecating/removing NONE mode.
Alexey, what do you think about the SYNC mode? In my experience, it does
not add much value as well. I would go as far as removing the
rebalancingMode parameter altogether (probably in 3.0).

Alexey, Igniters,
Could you please outline motivation answering following questions?
1. Does this mode generally work correctly today?
2. Can this mode be useful at all?
I can imagine that it might be useful in a transparent caching use
case (if I did not misunderstand).
