Subject Re: State of initially started cache with CacheRebalanceMode.SYNC ?
Date Mon, 13 Jun 2016 07:14:40 GMT
Hi Kristian,

This property means that a node that is being started and where a part of cache data is being
rebalanced won’t be considered for any cache related operations until the rebalancing has

In my understanding such a node won’t be considered for cache operations like put, get,
etc. until all the data is fully rebalanced on it. However this doesn’t prevent from getting
a cache reference on this node and ask for current cache size.
