Hello Mohammad. I reproduce your use case of Visor Console.
Now Console for command "cache -a" shows in the size column sum of primary key size and backup key size. In your case that is (15000 primary keys + 15000 backup keys) / 4 nodes = 7500. Created issue to divide cache size on primary and backup sizes: https://issues.apache.org/jira/browse/IGNITE-4356. -- View this message in context: http://apache-ignite-users.70518.x6.nabble.com/Cache-size-in-Partitioned-mode-as-seen-in-visor-tp9298p9363.html Sent from the Apache Ignite Users mailing list archive at Nabble.com.
