Subject Re: Server stores cache data on-heap if client has near cache - IGNITE-4662
Date Tue, 27 Mar 2018 20:32:05 GMT
When client node performs get it stores information about itself on server node, so-called
'reader'.
If another node updates cache entry, server node uses 'reader' info(because it tracks client
info) to find client and update cache entry in client's near cache.

PS. obviously, there may be plenty 'reader' nodes
